G.S. 15-180 provides that an appeal to this Court from a judgment in a criminal action “shall be perfected and the case for the Supreme Court settled, as provided in civil actions.” G.S. 1-282 provides that upon an appeal from a judgment in a civil action a copy of the appellant’s statement of the case on appeal “shall be served on the respondent within fifteen days from the entry of the appeal taken * * * Provided, that the judge trying the case shall have the power, in the exercise of his discretion, to enlarge the time in *303which to serve statement of case on appeal and exceptions thereto or counter statement of case.”
[1-3] By the terms of the statute, only the judge who tried the case can extend the time for serving the statement of the case on appeal and this Court has held that, having granted one extension, he may not grant another after the expiration of the term at which the judgment was entered. Machine Co. v. Dixon, 260 N.C. 732, 133 S.E. 2d 659. Normally, the effect of failure to serve the appellant’s statement of the case on appeal within the time fixed by the statute, or within the period of such authorized extension by the trial judge, is that upon such appeal the Supreme Court is limited to a consideration of the record proper and if no errors appear on the face thereof, the judgment will be affirmed. Machine Co. v. Dixon, supra; Twiford v. Harrison, 260 N.C. 217, 132 S.E. 2d 321. “It is the duty of appellant to see that the record is properly made up and transmitted to the court.” State v. Stubbs, 265 N.C. 420, 144 S.E. 2d 262.
 The record shows that on the day the judgment was pronounced in the superior court the defendant gave notice of appeal to this Court and the presiding judge then extended the time allowed by the statute for the service of the appellant’s statement of the case on appeal to 60 days. The two subsequent orders by the judge presiding at the trial, entered after the expiration of the term at which the judgment was pronounced, undertaking further to extend the time for the service of the appellant’s statement of the case on appeal and a subsequent order entered by a different judge, undertaking further to extend the time for the service of the statement of the case on appeal, were nullities.
[5-7] After an appeal is taken, the court from which it is taken has no authority with reference to the appellate procedure except that specifically conferred upon it by the statute. See Machine Co. v. Dixon, supra. Further extensions of time may be obtained only by petitions for certiorari directed to the court to which the appeal has been taken. No such petition was filed by the defendant with this Court. However, in the exercise of our discretion and in view of the imposition of the death penalty in the superior court, we, upon our own motion, treat the appeal as a petition for certiorari, allow the same and consider all assignments of error upon their merits as if the case on appeal had been served within the time properly allowed therefor.
Jurors Challenged Because Of Views Concerning Capital Punishment
 The record discloses no error in the rulings of the trial judge *304upon challenges for cause by the State to prospective jurors as the result of their stated views on the subject of capital punishment.
 Prior to the decision of the Supreme Court of the United States in Witherspoon v. Illinois, 391 U.S. 510, 88 S. Ct. 1770, 20 L. Ed. 2d 776, it was well established that, under the law of this State, it was not error to allow challenges for cause by the State to prospective jurors who stated they had “conscientious scruples against the infliction of the death penalty” in a case where such penalty might be inflicted pursuant to a verdict of guilty. State v. Spence (first hearing), 271 N.C. 23, 155 S.E. 2d 802; State v. Bumper (first hearing), 270 N.C. 521, 155 S.E. 2d 173; State v. Childs, 269 N.C. 307, 152 S.E. 2d 453. See also State v. Peele, 274 N.C. 106, 161 S.E. 2d 568. In State v. Vick, 132 N.C. 995, 43 S.E. 626, the Court quoted with approval the following statement in 17 A. and E. Enc. 1134:
“Though no such ground for challenge is to be found stated in the English cases, in the United States, since the early part of the nineteenth century, the fact that one has conscientious scruples against the infliction of capital punishment has been regarded as disqualifications furnishing ground for challenge by the prosecution, on a trial for an offense which may be punished by death.”
The law of this State, as distinguished from the Constitution of the United States, has not been changed in this respect since those decisions were rendered.
 The Constitution of the United States, as interpreted by the Supreme Court of the United States in the Witherspoon case, supra, is, of course, controlling insofar as it conflicts with the law of this State and we so recognized in State v. Spence (hearing on remand), 274 N.C. 536, 164 S.E. 2d 593. There we allowed a new trial because the record contained a stipulation that 79 of 150 veniremen were successfully challenged for cause “because of their stated opposition to capital punishment,” this being contrary to the Witherspoon decision. The question now before us is whether the Constitution of the United States, as interpreted in the Witherspoon case, is violated by the allowance of the State’s challenges for cause shown in the present record.
 The majority opinion in the Witherspoon case sharply defines the line drawn by that decision by both positive and negative statements. The Court affirmatively stated its holding as follows:
“Specifically, we hold that a sentence of death cannot be *305carried out if the jury that imposed or recommended it was chosen by excluding veniremen for cause simply because they voiced general objections to the death penalty or expressed conscientious or religious scruples against its infliction.” (Emphasis added.)
Speaking negatively, the Court said:
“The issue before us is a narrow one. It does not involve the right of the prosecution to challenge for cause those prospective jurors who state that their reservations about capital punishment would prevent them from making an impartial decision as to the defendant’s guilt. Nor does it involve the State’s assertion of a right to exclude from the jury in a capital case those who say that they could never vote to impose the death penalty or that they would refuse even to consider its imposition in the case before them. For the State of Illinois did not stop there, but authorized the prosecution to exclude as well all who said they were opposed to capital punishment and all who indicated that they had conscientious scruples against inflicting it.” (Emphasis added.)
Again, in Footnote 21, the Court said:
“We repeat, however, that nothing we say today bears upon the power of a State to execute a defendant sentenced to death by a jury from which the only veniremen who were in fact excluded for cause were those who made unmistakably clear (1) that they would automatically vote against the imposition of capital punishment without regard to any evidence that might be developed at the trial of the case before them, or (2) that their attitude toward the death penalty would prevent them from making an impartial decision as to the defendant’s guilt”
 Prospective juror Corum stated specifically that his feeling against capital punishment was so strong that in no event could he ever bring out a verdict of guilty if he knew the penalty would be death.
Prospective juror Thompson stated that even if the evidence should convince him beyond a reasonable doubt of the guilt of the defendant he would have “moral or religious scruples against bringing in a verdict of guilty in this particular case” if he “knew that the death penalty would be invoked.” Prospective juror Best stated that even though, after hearing all of the evidence, he was satisfied beyond a reasonable doubt that the defendant is guilty he would have “religious or moral scruples” which would prevent him “from *306bringing out a verdict of ‘guilty’ ” if he knew the sentence would be death.
[11, 12] It is true that, at the time of the trial of this defendant in the superior court, G.S. 14-17 provided that the punishment for murder in the first degree would be imprisonment for life if, at the time of rendering its verdict in open court, the jury should so recommend, and, under the decisions of this Court, it was the duty of the trial judge in a capital case to instruct the jury that it might, in its unbridled discretion, render its verdict of guilty with such recommendation, which would then be binding upon the court in the matter of sentence. State v. Carter, 243 N.C. 106, 89 S.E. 2d 789; State v. McMillan, 233 N.C. 630, 65 S.E. 2d 212. The jury actually selected to try the defendant in the present case was so instructed. Since the verdict of a jury must be unanimous, it necessarily follows that if only one juror had refused to consent to a verdict of guilty of murder in the first degree without a recommendation that the punishment be imprisonment for life, the death sentence could not be imposed upon the defendant. Consequently, prospective jurors Corum, Thompson and Best could each have served upon the jury in the present case and rendered a verdict of guilty without violating his stated moral or religious scruples against the death penalty.
 It does not follow, however, that the sustaining of the State’s challenges to these prospective jurors violated the rule of the Witherspoon case, supra. It is perfectly clear from their answers in the record, upon voir dire examination, that each of these prospective jurors, before hearing any of the evidence, had already made up his mind that he would not return a verdict pursuant to which the defendant might lawfully be executed, whatever the evidence might be. In the language of the majority opinion in the Witherspoon case, these jurors made it clear that “they could never vote to impose the death penalty” and “they would refuse even to consider its imposition in the case before them,” and “they would automatically vote against the imposition of capital punishment without regard to any evidence that might be developed at the trial of the case before them.”
 The State, as well as the defendant, is entitled to a jury which will give it a fair and impartial verdict upon every issue properly presented by the evidence, including the question of whether, upon the evidence, the defendant, believed by them beyond any reasonable doubt to be guilty of first degree murder, should be executed or should be imprisoned for life. The decision in Witherspoon v. Illinois, supra, does not deprive the State of this right. *307 Irving v. Breazeale, 400 F. 2d 231, 236; Williams v. Dutton, 400 F. 2d 797, 805; United States v. Valentine, 288 F. Supp. 957, 966; State v. Mathis, 52 N.J. 238, 245 A. 2d 20, 23, 26; State v. Smith, (Wash.), 446 P. 2d 571. As the Supreme Court of the United States said in Swain v. Alabama, 380 U.S. 202, 85 S. Ct. 824, 13 L. Ed. 2d 759:
“The function of the challenge is not only to eliminate extremes of partiality on both sides, but to assure the parties that the jurors before whom they try the case will decide on the basis of the evidence before them, and not otherwise. * * *
Although historically the incidence of the prosecutor’s challenge has differed from that of the accused, the view in this country has been that the system should guarantee ‘not- only freedom from any bias against the accused, but also from any prejudice against his prosecution. Between him and the State the scales are to be evenly held.’ Hayes v. Missouri, 120 U.S. 68, 70.”
[15, 16] Following the recital of the voir dire examinations of the above prospective jurors and the rulings of the court sustaining the challenges of the State to them, the record contains the following statement:
“There were 50 prospective jurors called to the stand before a jury was seated in this case and every juror called to the stand was asked the similar questions as set out above concerning capital punishment.”
There is nothing in this statement to show any error entitling the defendant to a new trial. It shows only that 36 prospective jurors were excused, 14, including two alternate jurors, having been selected. The record does not show how many of the 36 were challenged by the defendant or how many were challenged by the State or how many were challenged by either party peremptorily. Of those challenged successfully for óause, with the exception of the three named above, the record does not show that the challenge was based upon the answer of a single prospective juror to any question with reference to capital punishment. Indeed, the record does not show the answer of any juror to any question upon this subject other than the three prospective jurors above mentioned. The statement that “the similar questions as set out above concerning capital punishment” were asked each juror discloses no error, first because it does not show sufficiently the content of any question since those asked the prospective jurors Corum, Thompson, and Best were not identical, and second because there was certainly no error in allowing any ques*308tion identical to that propounded to any one of those three prospective jurors. Even if a prospective juror’s answer to such a question were not sufficient to support a challenge for cause, it would certainly be proper to ask the question in order to permit the intelligent use of the peremptory challenges allowed by law to the State. See Swain v. Alabama, supra.
We, therefore, conclude that there is nothing in this record indicating any merit in the contention of the defendant that he has been denied any right under the Constitution of the United States, or under the law of this State, in the sustaining of any challenge for cause by the State by reason of the prospective juror’s statement of his views on the subject of capital punishment.
Jurors Excused Because Of Unwillingness To Take Oath
 The court’s action in excusing, in its discretion and upon its own motion, three prospective jurors who refused to take the customary oath, is not ground for granting the defendant a new trial.
According to the record, only one of these prospective jurors expressed a willingness to affirm rather than swear. The record indicates that no question was propounded to any of them. They were not challenged. They were excused by the court. The record discloses no other information about any of them or concerning the reason for the court’s action. The record does not state that they were excused because of their objection to taking an oath. While the record shows an exception by the defendant to each of these actions of the court, it does not show any objection thereto interposed at the time. In oral argument in this Court, counsel for the defendant stated frankly that no such objection was then interposed, the exceptions having been entered in preparation of the statement of the case on appeal.
[17-19] The desire of a prospective juror to affirm rather than take an oath is not, of itself, cause for challenge in this State. See: G.S. 9-14; G.S. 11-11. On the other hand, nothing else appearing, even the erroneous allowance of an improper challenge for cause does not entitle the adverse party to a new trial, so long as only those who are competent and qualified to serve are actually empaneled upon the jury which tried his case. This is especially true where, as here, the adverse party did not exhaust his peremptory challenges. See: State v. Vann, 162 N.C. 534, 77 S.E. 295; State v. Cunningham, 72 N.C. 469, 474. The defendant is not entitled to a jury of his selection or choice but only to a jury selected pursuant to law and without unconstitutional discrimination against a class or substantial *309group of the community from which the jury panel is drawn. He has no “vested right to a particular juror.” State v. Vann, supra.
 It has long been established in this State that it is the right and duty of the court to see that a competent, fair and impartial jury is empaneled and, to that end, the court-, in its discretion, may excuse a prospective juror without a challenge by either party. State v. Vann, supra; State v. Vick, supra; State v. Boon, 80 N.C. 461; State v. Jones, 80 N.C. 415. It is immaterial that this is done as the result of information voluntarily disclosed by the prospective juror without questioning. State v. Vick, supra.
 We must bear in mind that the trial judge had these prospective jurors before him and thus had an opportunity to observe their apparent qualifications, an advantage which a virtually empty record does not afford us. With nothing in the record to guide us, we cannot say that there was not in the appearance or manner of these three prospective jurors sufficient indication of their lack of qualification to serve as jurors in a case of this serious and important nature. But even if we might have reached a different conclusion in this respect from that reached by the trial judge, it has been settled in this State since as long ago as State v. Ward, 9 N.C. 443, that an irregularity in forming a jury is waived by silence of a party at the time of the court’s action. There, Henderson, J., later C.J., said, “He shall not by consent of this kind, take a double chance” on acquittal by the jury so selected or a new trial because of such irregularity in the selection. See also State v. Boon, supra. For a recent recognition of the discretion of the trial judge in excusing a prospective juror without a challenge, see State v. Spence (first hearing), 271 N.C. 23, 32, 155 S.E. 2d 802.
 The defendant does not contend that this action of the trial judge was a systematic exclusion from the jury of members of a class to which the defendant himself belongs. His contention is that the court excluded from the jury a class of persons, i.e., those who have scruples against taking an oath, and thereby deprived the defendant of a jury drawn from a fair cross section of the community. See Witherspoon v. Illinois, supra; Hernandez v. Texas, 347 U.S. 475, 74 S. Ct. 667, 98 L. Ed. 866; Thiel v. Southern Pacific Co., 328 U.S. 217, 66 S. Ct. 984, 90 L. Ed. 1181; Smith v. Texas, 311 U.S. 128, 61 S. Ct. 164, 85 L. Ed. 84.
There is nothing in the record to indicate that persons who have conscientious scruples against taking an oath that they will properly perform their duties as jurors constitute any substantial proportion of the prospective jurors in Wayne County and we know of *310nothing which would so indicate. Nor does the record show, or circumstances known to us indicate, that jurors with such scruples would be less inclined than others to convict or to impose the death penalty. Such scruples are not limited to members of a single religious denomination or sect. It may well be that such a person would be a strict constructionist of the more retributive provisions of the Mosaic law. In any event, the defendant, having the same opportunity as the trial judge to observe these three prospective jurors in the courtroom, did not object to their being excused from the jury until after the verdict was rendered.
 Hernandez v. Texas, supra, establishes that a defendant complaining of group discrimination in the selection of the jury which tried him has the burden of proving that persons excluded from the jury are members of a separate class in the county from which the jury comes. Swain v. Alabama, supra, states that the first step to be taken by such a defendant is to establish that the persons excluded belong to an “identifiable group in the community which may be the subject of prejudice.” That is, the ultimate question in such a situation is whether the jury selected represented a fair cross section of the entire community. The burden is upon the defendant to establish that it did not. Swain v. Alabama, supra; Hernandez v. Texas, supra. The record before us does not lead to this conclusion.
Introduction Of Photographs, Clothing, Etc.
[24, 32, 33] The court did not err in the admission, over objection, of the clothing and washcloth found upon the body of the deceased child, the shovel obtained by the officers from the residence of the defendant with his permission or the photographs used by the witnesses of the State to illustrate their testimony concerning the location and appearance of the place where the child’s body was found buried and the condition of the body. It is not contended that the articles of clothing and the washcloth were not properly authenticated and identified or that the photographs are in any respect inaccurate portrayals of what they purport to represent or were not properly taken and authenticated.
 In State v. Speller, 230 N.C. 345, 53 S.E. 2d 294, this Court held there was no error in admitting into evidence garments worn by the alleged victim of a rape and murder, which garments bore tears and stains corroborative of the State’s theory of the case. In State v. Vann, supra, it was held that there was no error in permitting articles found at the place of a homicide to be exhibited to the jury, these being competent to identify the body, or to establish a fact *311relevant to the State’s theory of the case or to enable the jury to realize more completely the cogency and force of the testimony of witnesses. Thus, clothing worn by the alleged victim of a felonious homicide may properly be introduced in evidence to show the location of a wound upon the person of the deceased. State v. Fleming, 202 N.C. 512, 163 S.E. 453. See also: State v. Bass, 249 N.C. 209, 105 S.E. 2d 645; State v. Petry, 226 N.C. 78, 36 S.E. 2d 653.
 In the present case, the jury was properly instructed that the photographs in question were allowed in evidence for the sole purpose of illustrating the testimony of witnesses and not as substantive evidence. See: State v. Norris, 242 N.C. 47, 86 S.E. 2d 916; State v. Perry, 212 N.C. 533, 193 S.E. 727. The fact that a photograph depicts a horrible, gruesome and revolting scene, indicating a vicious, calculated act of cruelty, malice or lust, does not render the photograph incompetent in evidence, when properly authenticated as a correct portrayal of conditions observed by and related by the witness who uses the photograph to illustrate his testimony. State v. Porth, 269 N.C. 329, 153 S.E. 2d 10; State v. Rogers, 233 N.C. 390, 64 S.E. 2d 572, 28 A.L.R. 2d 1104; State v. Gardner, 228 N.C. 567, 46 S.E. 2d 824; Stansbury, North Carolina Evidence, 2d Ed., § 34. For a collection of authorities to the same effect from other jurisdictions, see Annot., 73 A.L.R. 2d 769.
[26-28] “Ordinarily, photographs are competent to be used by a witness to explain or illustrate anything it is competent for him to describe in words.” State v. Gardner, supra. The fact that the photographs are in color does not affect their admissibility. State v. Hill, 272 N.C. 439, 158 S.E. 2d 329; People v. Moore, 48 Cal. 2d 541, 310 P. 2d 969; Commonwealth v. Makarewicz, 333 Mass. 575, 132 N.E. 2d 294; Annot., supra, p. 811. Thus, in a prosecution for homicide, photographs showing the condition of the body when found, the location where found and the surrounding conditions at the time the body was found are not rendered incompetent by their portrayal of the gruesome spectacle and horrifying events which the witness testifies they accurately portray. State v. Stanley, 227 N.C. 650, 44 S.E. 2d 196; State v. Cade, 215 N.C. 393, 2 S.E. 2d 7.
[29-31] It is not necessary that the photograph be taken by the witness, if the witness testifies that it correctly represents what the witness observed. State v. Stanley, supra; Stansbury, North Carolina Evidence, 2d Ed., § 34. A photograph of the body of the deceased is not inadmissible by reason of the fact that it was taken after the body had been moved from the place where originally found and carried to the morgue or other place for examination. *312 State v. Gardner, supra; State v. Miller, 219 N.C. 514, 14 S.E. 2d 522. Obviously, the fact that the photograph was taken and portrays the condition of the body at some time after the homicide occurred does not, of itself, make the photograph incompetent. State v. Hill, supra; State v. Lentz, 270 N.C. 122, 153 S.E. 2d 864; State v. Porth, supra; Stansbury, North Carolina Evidence, 2d Ed., § 34.
 The photographs in question, meeting the test of relevancy and being properly authenticated, were properly admitted in evidence for the limited purpose stated by the trial judge, and, consequently, there was no error in permitting the jury to see them. State v. Mays, 225 N.C. 486, 35 S.E. 2d 494.
 The shovel taken by the officers from the defendant’s home, with his permission, immediately after the child’s body was removed from the place where the defendant had admitted he buried it, was clearly competent for admission in evidence. The defendant’s statement to the officers was that he had dug the shallow grave with “his shovel” which he then returned to the place behind his house where the officers found it covered with dirt of the same type as that of the soil in the child’s burial place.
Evidence Tending To Show Another Crime
 There was no error in allowing the pathologist, properly qualified as an expert witness, to testify as to the conditions he observed upon the child’s body and his conclusion therefrom that she had been raped, nor was it error to permit this witness to use the properly authenticated photographs of the body to illustrate his testimony.
[34, 35] The defendant contends that this was error because it was testimony tending to show the commission of a criminal offense (rape) other than that of murder for which the defendant was on trial. While it is well established that evidence of other crimes, having no bearing upon the crime for which the defendant is on trial, may not be introduced prior to his taking the stand as a witness in his own behalf, it is equally well settled that all facts, relevant to the proof of the defendant’s having committed the offense with which he is charged, may be shown by evidence, otherwise competent, even though that evidence necessarily indicates the commission by him of another criminal offense. State v. Christopher, 258 N.C. 249, 128 S.E. 2d 667; State v. McClain, 240 N.C. 171, 81 S.E. 2d 364; State v. Harris, 223 N.C. 697, 28 S.E. 2d 232; Stansbury, North Carolina Evidence, 2d Ed., § 91. Thus, such evidence of other offenses is competent to show “the crime charged was committed for the purpose of concealing another crime,” State v. Beam, 184 N.C. 730, 115 *313S.E. 176, or to show “a motive on the part of the accused to commit the crime charged,” State v. McClain, supra, or to show the quo animo, intent, design, guilty knowledge, or scienter, or to make out the res gestee, or to exhibit a chain of circumstances in respect of the matter on trial, when such crimes are so connected with the offense charged as to throw light upon one or more of these questions. State v. Christopher, supra; State v. Harris, supra; Stansbury, North Carolina Evidence, 2d Ed., §§ 91 and 92.
In State v. Westmoreland, 181 N.C. 590, 107 S.E. 438, in sustaining a death sentence for murder in the first degree, this Court, speaking through Walker, J., said. “There are authorities for the position that any unseemly conduct toward the corpse of the person slain, or any indignity offered it by the slayer, and also concealment of the body, are evidence of expressed malice, and of premeditation and deliberation in the slaying, depending, of course, upon the peculiar circumstances of the case.”
 It was entirely proper in the present instance to permit the State to offer this evidence, including the photographs, to establish the motive, premeditation, deliberation and malice on the part of the defendant for and in the murder with which he was charged by the State.
Testimony 4s To Insanity
 There was no error in permitting the psychiatrist, duly qualified as an expert witness, who examined the defendant, pursuant to the order of the court, some three and a half months after the alleged offense, to testify that upon the basis of his observation of the defendant he was of the opinion that the defendant “knew right from wrong” on the date the offense was alleged to have been committed.
This witness was duly qualified as an expert witness in the field of psychiatry and testified to his observation of and examination of the defendant over a substantial period of confinement of the defendant for that purpose in the State hospital. He was called by the State to rebut the testimony of the defendant’s mother that, in her opinion, the defendant was not capable of distinguishing between, right and wrong in relation to the charge of murder on the date the-offense was alleged to have occurred, her testimony being upon the-basis of her observation of the defendant prior to and after that, date.
[37, 38] In this State, the test of insanity as a defense to an alleged criminal offense is the capacity of the defendant to distinguish *314between right and wrong at the time of and in respect of the matter under investigation. State v. Spence (first hearing), 271 N.C. 23, 155 S.E. 2d 802; State v. Matthews, 226 N.C. 639, 39 S.E. 2d 819. Evidence tending to show the mental condition of the accused, both before and after the commission of the act, is competent provided it bears such relation to the defendant’s condition of mind at the time of the alleged crime as to be worthy of consideration in respect thereto. State v. Duncan, 244 N.C. 374, 93 S.E. 2d 421. Obviously, it would not be practicable to limit expert testimony upon this subject to witnesses who had the defendant under observation at the instant the act in question was committed.
 In State v. Matthews, supra, it is said that a witness may not testify as to his opinion concerning the mental capacity of the defendant to commit the specific crime with which he is charged. The State’s expert witness in the present case did not so testify. He testified that in his opinion, based upon his subsequent examination of the defendant, the defendant knew “right from wrong” on the day of the alleged offense. The witness, being an expert in the field of psychiatry, was competent to relate to the jury such opinion though he did not observe the defendant on the precise date of the alleged offense.
 It is to be noted that two other witnesses, the only ones who were in the defendant’s company and who did observe him on that day, one when he left her home with the child at 6 p.m., and the other when he entered the restaurant and reported the child missing at approximately 9:45 p.m., each testified that he appeared to be and acted “normal.” His own witnesses, with the exception of his mother, testified that they observed no evidences of insanity. The burden rests upon the defendant to establish this defense “to the satisfaction of the jury.” State v. Harris, 223 N.C. 697, 28 S.E. 2d 232.
Comment By Trial Judge
 The defendant assigns as error the comment of the trial judge in response to the defendant’s objection to a statement by the solicitor in the latter’s argument to the jury. The statement by the solicitor was, “his [the defendant’s] mother said she didn’t remember whether she was charged with killing her first husband or not.” When the defendant’s counsel objected, the court replied, “I remember distinctly that she said it.” The defendant is not entitled to a new trial on this account.
The narrative summary of the testimony of the defendant’s mother set forth in the record before us does not contain this alleged *315statement by her. She did testify: “I have been married twice. I did not kill my second husband but I was convicted and served time for his murder.” There was testimony by another witness that her first husband (the father of the defendant) “committed suicide when (the defendant) was only four months old.” In reviewing the evidence in his charge to the jury, as he was required to do by the statute, the trial judge again stated that the defendant’s mother testified “she was convicted of murdering her second husband, that she did not recall and does not remember whether she was charged with killing her first husband, the father of the defendant.” To this statement the defendant did not object and he made no attempt to call its alleged inaccuracy to the attention of the court.
 It is not required that the appellant set forth in his statement of the case on appeal the evidence in its entirety. On the contrary, G.S. 1-282 states that the case on appeal shall be “a concise statement of the case,” and it is common practice to omit portions of the testimony deemed by the parties of no consequence upon the appeal. Our examination of the entire charge of the court discloses that there were a number of instances in which evidence summarized therein by the judge for the benefit of the jury is not otherwise reflected in the record before us. These indicate that in the preparation of the statement of the case on appeal the appellant did not undertake to set out the evidence in its entirety.
 The court correctly instructed the jury that it was to recall all of the testimony and to be guided by its recollection and not by the court’s summary of the evidence. While it is error for the court to express an opinion to the jury reflecting upon the credibility of a witness, State v. Auston, 223 N.C. 203, 25 S.E. 2d 613, we think it a strained construction of the remark of the court in this instance to call it an expression of opinion by the court as to the credibility of the witness. If it was, it is obvious that the statement was not prejudicial error since the witness had admitted her conviction of the murder of the second husband. It is inconceivable that this statement by the court, even if inaccurate, affected the verdict of the jury. It does not justify awarding a new trial to the defendant. The point is not stressed by the defendant in his brief.
Validity Of The Death Sentence
 The defendant does not, in his assignments of error or in his-brief, question the validity of the judgment imposing the death sentence, as such. Nevertheless, his appeal is, itself, an exception to the judgment and thus brings before us for review all matters! *316appearing on the face of the record proper, including the sufficiency of the verdict to support the imposition of the death sentence. 1 Strong, North Carolina Index 2d, Appeal and Error, § 26, and cases there cited. We, therefore, turn to the question of whether the verdict of guilty of murder in the first degree, without more, authorized the superior court to enter its judgment sentencing the defendant to death by asphyxiation.
In State v. Peele, supra, we said that the decision of the Supreme Court of the United States in United States v. Jackson, 390 U.S. 570, 88 S. Ct. 1209, 20 L. Ed. 2d 138, “is not authority for holding the death penalty in North Carolina may not be imposed under any circumstances for the crime of rape.” Bobbitt and Sharp, JJ., concurring in result, were of the opinion that the Peele case did not present for this Court’s determination whether the Jackson case “invalidates the death penalty under present North Carolina statutes.”
In State v. Spence (hearing on remand), 274 N.C. 536, 164 S.E. 2d 593, we said, “This Court has already held, in State v. Peele, supra, that United States v. Jackson, * * * is not authority for holding capital punishment is abolished altogether in North Carolina.” Bobbitt and Sharp, JJ., dissented from so much of the decision in the Spence case as directed a new trial, their view being “the death penalty provisions of our present statutes, when considered in the light of Jackson, are invalid.”
Whether or not the question of the effect of United States v. Jackson, supra, upon G.S. 14-17 was before us in either State v. Peele, supra, or in State v. Spence, supra, it is before us in the present case. We reaffirm the views expressed upon this question in the majority opinions of this Court in State v. Peele, supra, and State v. Spence, supra.
G.S. 14-17 provides:
“Murder in the first and second degree defined; punishment. — A murder which shall be perpetrated by means of poison, lying in wait, imprisonment, starving, torture, or by any other kind of willful, deliberate and premeditated killing, or which shall be committed in the perpetration or attempt to perpetrate any arson, rape, robbery, burglary or other felony, shall be deemed to be murder in the first degree and shall be punished with death; Provided, if at the time of rendering its verdict in open court, the jury shall so recommend, the punishment shall be imprisonment for life in the State’s prison, and the Court shall so instruct the jury. * * *”
*317The proviso was added by an amendment enacted in 1949, the remainder of the statute having been enacted in 1893.
G.S. 15-162.1 was enacted in 1953. Though subsequently repealed by Chapter 117 of the Session Laws of 1969, it was in effect at the time of the defendant’s trial below. It provided that any person, charged in a bill of indictment with murder in the first degree, might, after arraignment, tender in writing, signed by himself and his counsel, a plea of guilty of such crime, and the State, with the approval of the court, might accept such plea or reject it, in which latter event the trial should proceed upon a plea of not guilty and the tender of the plea of guilty would have no legal significance. G.S. 15-162.1 then provided:
“(b) In the event such plea is accepted, the tender and acceptance thereof shall have the effect of a jury verdict of guilty of the crime charged with recommendation by the jury in open court that the punishment shall be imprisonment for life in the State’s prison; and thereupon, the court shall pronounce judgment that the defendant be imprisoned for life in the State’s prison.”
 It is to be noted that G.S. 14-17, providing for the sentence to be imposed upon a verdict returned by the jury, and G.S. 15-162.1, providing for the sentence to be imposed upon an accepted plea of guilty, were separate and distinct statutes, G.S. 14-17 having been in full effect long before G.S. 15-162.1 was enacted. It cannot, therefore, be doubted that they were always separate and distinct legislative provisions, that G.S. 14-17 is capable of standing alone as it did for several years and that the validity of G.S. 14-17 cannot be affected adversely by the invalidity, if any, of G.S. 15-162.1. The repeal of G.S. 15.162.1, leaving G.S. 14-17 intact, shows the 1969 Legislature’s intent for G.S. 14-17 to stand alone.
In United States v. Jackson, supra, the Supreme Court of the United States reversed a judgment of the District Court which had dismissed an indictment for violation of the Federal Kidnapping Act, 18 U.S.C. § 1201. That Act provided:
“Whoever knowingly transports in interstate * * * commerce, any person who has been unlawfully * * ® kidnaped * * * and held for ransom * * * shall be punished (1) by death if the kidnaped person has not been liberated unharmed, and if the verdict of the jury shall so recommend, or (2) by imprisonment for any term of years or for life, if the death penalty is not imposed.”
*318As the Supreme Court of the United States observed in its opinion in the Jackson case, the Federal Kidnapping Act, as originally enacted by Congress in 1932, contained no provision for the infliction of capital punishment. An amendment, enacted in 1934, inserted the provision authorizing the death penalty to be imposed under specific circumstances, “if the verdict of the jury shall so recommend.” The decision of the Jackson case was that the amendment of 1934 was unconstitutional for the reason that it imposed “an impermissible burden upon the exercise of” the defendant’s constitutional right to demand a jury trial.
Prior to the adoption of the 1934 amendment, one accused of violating the Federal Kidnapping Act could exercise his constitutional right to demand a jury trial without risk of the death penalty if the jury found him guilty. Under the 1934 amendment, he could not. For this reason, the Court held the 1934 amendment authorizing the jury to fix the penalty at death was unconstitutional, not because the death penalty, per se, is unconstitutional but because the 1934 amendment discouraged the exercise of the defendant’s constitutional right to a trial by jury. The Court then said that the original Federal Kidnapping Act, which contained no provision discouraging the exercise of the right to a jury trial, could and should stand as a separate, divisible statutory enactment apart from the 1934 amendment. Consequently, the Court struck from the act the 1934 amendment, leaving the act in its original form, and held the indictment valid.
[44, 45] The legislative history of G.S. 14-17 and G.S. 15-162.1 bears no similarity whatever to the legislative history of the Federal Kidnapping Act. If there was anything in these two statutes which discouraged the defendant from demanding a jury trial, it was found in G.S. 15-162.1, the later of the two separate and distinct statutes. The constitutionality of G.S. 15-162.1, while in effect, is not presently before us and we express no opinion with reference to its then validity. If, however, that statute is subsequently held invalid upon the ground suggested in United States v. Jackson, supra, or otherwise, such decision will not and cannot affect the validity of G.S. 14-17, a wholly separate, independent, previously existing and surviving statute. Thus, the decision in United States v. Jackson, supra, did not, at the time of the judgment in this case, and does not now forbid the courts of this State to impose the sentence of death pursuant to a verdict of the jury in accordance with G.S. 14-17.
 United States v. Jackson, supra, arose on a motion to dismiss the indictment. The present case comes before us after the de*319fendant has pleaded to the indictment. In the Jackson case, it was not known how the defendant might wish to plead. In this case, the defendant pleaded not guilty and was tried by a jury. Whatever the effect of G.S. 15-162.1 might have been upon other defendants charged with first degree murder, its being in the statute book at the time of this defendant’s arraignment and trial did not discourage him from exercising his constitutional right to a trial by jury.
 There remains for decision the question of whether the imposition of the death penalty for first degree murder is unconstitutional per se. The Supreme Court of the United States has not so declared. We find nothing in the Constitution of the United States which leads us to such a conclusion.
 The imposition of the death penalty upon a conviction of murder is expressly authorized by Article XI, § 2, of the Constitution of North Carolina, adopted in 1868. G.S. 14-17 was enacted pursuant to that constitutional provision. The history of this provision in our State Constitution is of major significance in the determination of the effect of the Fourteenth Amendment to the Constitution of the United States upon the authority of North Carolina to impose the death penalty. This provision reads as follows:
“Death punishment. — The object of punishments being not only to satisfy Justice, but also to reform the offender, and thus prevent crime, murder, arson, burglary, and rape, and these only, may be punishable with death, if the General Assembly shall so enact.”
Prior to the Constitution of 1868, there was no reference to the death penalty in the Constitution of North Carolina. The death penalty was, nevertheless, imposed in many cases in this State from the winning of our independence down to 1868, just as it was imposed during that period by the courts of the other states of the Union, under the provisions of statutes enacted in recognition of the power of the Legislature of a state to fix, in its discretion, a punishment for crime, unless forbidden to do so by a constitutional provision.
It is a matter of well known history that the Constitution of 1868 was adopted by this State in order to meet conditions imposed by the Federal Congress upon the right of this State to send its lawful representatives to the Congress following the Civil War. See: Woodrow Wilson, History of the American People, Vol. V, pp. 37, 44, 46; Hamilton, Reconstruction In North Carolina, pp. 187, 215, 217, 288. It was adopted contemporaneously with the ratification of *320the Fourteenth Amendment to the Constitution of the United States. Obviously, the entire Constitution of North Carolina of 1868 was examined with care by the very Congress which proposed the Fourteenth Amendment to the states and was approved by that Congress. See Hamilton, op. cit., p. 288.
 In the light of this constitutional history, it is inconceivable that the Congress which submitted the Fourteenth Amendment, or the states which ratified it, regarded anything therein as prohibiting a state to impose the death penalty upon conviction of first degree murder. The widespread and frequent imposition of the death penalty by the courts of the several states in the one hundred years which have elapsed since the adoption of the Fourteenth Amendment, and the acquiescence therein by the Supreme Court of the United States in cases innumerable, clearly refute the suggestion that the Fourteenth Amendment prevents the State of North Carolina from sentencing this defendant to death pursuant to G.S. 14-17.
The constitutionality of a state statute cannot be determined by taking a Gallup poll of the opinion of the public with reference to the efficacy or the morality of a statute authorizing the imposition of the death penalty, even if it be assumed that the question can be framed so as to be understood by all of those reached by the takers of the “straw vote.” The power of a sovereign state of this Union to enact legislation is to be determined by the courts, not by public opinion polls or by writings in sociological journals or treatises. It is the duty of this Court to determine whether the State of North Carolina has that power in the light of the history of the constitutional provisions said to forbid its exercise and in the light of the long line of judicial interpretations of those constitutional provisions. Our determination is not to be guided by tabulations of answers to public opinion polls, said to have been received by the poll takers from unknown members of the public, not shown to have been advertent to either the language of such constitutional provisions, their history or their interpretation by the courts-of this country.
 It is not for this Court, or any other court, to determine whether the provision imposing the death penalty for the commission of first degree murder is or is not a wise policy for a state concerned with the protection of its people from such acts. It is not for us, or any other court, to determine whether a statute providing for the death penalty is a more effective deterrent to first degree murder than some other penal provision would be. It is for the Legislature of North Carolina to make that decision. It has done so in the enactment of G.S. 14-17 and, within recent days, has reaffirmed that *321policy determination by its rejection of a proposal to abolish the provision for the imposition of the death penalty. The sole question before us, in this connection, is whether there is any provision of the State or Federal Constitution which prevents the Legislature of North Carolina from adopting such policy and enacting a statute to carry it into effect. We find no such provision in either Constitution.
Review Of The Record Ex Mero Motu
 It has long been the rule of this Court that “in capital cases the Supreme Court will review the record and take cognizance of prejudicial error ex mero motu.” See State v. Oakes, 249 N.C. 282, 106 S.E. 2d 206. We have reviewed the entire record in this case, without limitation to the assignments of error made by the defendant.
The defendant has been represented throughout this proceeding with diligence and skill by two able attorneys, experienced in the practice of criminal law in the courts of Wayne County and in this Court. They were appointed to represent him, without expense to him, several months prior to the calling of his case for trial. He has been given, free of expense to him, expert psychiatric examination to determine his mental competency to plead to the charge brought against him. Without expense to him, the record of his trial and the brief of his able counsel have been prepared and made available to this Court for review. We have carefully considered every part of that record and the earnest arguments of his counsel. The State of North Carolina has afforded him a fair trial in accordance with its established procedures applicable to all such cases.
The evidence is ample to support the finding that the defendant, a sane man, with malice aforethought and with premeditation and deliberation, killed his four year old stepdaughter, Kathy Carr, that, after first grievously injuring her in a manner she could not understand, he took a shovel, placed it and the bleeding child, who had been taught to love and trust him, in his car, drove 18 miles to a lonely area, left the little child in the car, went into the woods, dug her grave, returned to the car and, taking her little hand in his, led her through the dark woods to the hole he had dug, there smothered her to death with his hands, threw her body into the hole and covered it in such a manner that only the defendant and God would know her resting place.
The jury has, upon this evidence, under full and correct instructions of the trial judge as to the law, found him guilty of first degree murder and has concluded that he should be executed in the manner *322provided by law. The statute of this State authorized the jury to return such verdict and required the judge, thereupon, to enter the judgment contained in the record. We find no error of law in the trial which would justify us in granting the defendant a new trial or in vacating or modifying the judgment.
