Briefly stated, the defendant Board through Wright contracted with the electricians to rebuild a part of its electric line for the lump sum of $30.00. The electricians agreed to undertake and complete the job if the defendant would furnish a truck and two helpers. After some discussion about trimming some trees to clear the wires, at the suggestion of Lovett, the poles were shortened so as to clear the wires without cutting the trees. After deceased was killed the work was temporarily stopped, and defendant notified the other electricians it wanted the job completed. They, and not the defendant, obtained other help and completed the job. Defendant paid in a lump sum by check.
What was the relationship created by this contract? Were the electricians, including the deceased, employees or independent contractors? This is the decisive question.
*15While the Commission concluded that the electricians were employees, this is not controlling. There is no substantial controversy as to the facts. This being true, the relationship created by the contract is a question of law, and the conclusion of the Commission is reviewable. Thomas v. Gas Co., 218 N. C., 429, 11 S. E. (2d), 297; Beach v. McLean, 219 N. C., 521, 14 S. E. (2d), 515.
The distinction between “servant” or “employee” and “independent contractor” has been frequently discussed and defined by this and other courts as well as by textwriters. Young v. Lumber Co., 147 N. C., 26, 60 S. E., 654; Gay v. R. R., 148 N. C., 336, 62 S. E., 436; Denny v. Burlington, 155 N. C., 33, 70 S. E., 1085; Beal v. Fiber Co., 154 N. C., 147, 69 S. E., 834; Johnson v. R. R., 157 N. C., 382, 72 S. E., 1057; Harmon v. Contracting Co., 159 N. C., 22, 74 S. E., 632; Embler v. Lumber Co., 167 N. C., 457, 83 S. E., 740; Simmons v. Lumber Co., 174 N. C., 220, 93 S. E., 736; Cole v. Durham, 176 N. C., 289, 97 S. E., 33; Greer v. Construction Co., 190 N. C., 632, 130 S. E., 739; Aderholt v. Condon, 189 N. C., 748, 128 S. E., 337; Drake v. Asheville, 194 N. C., 6, 138 S. E., 343; Lumber Co. v. Motor Co., 192 N. C., 377, 135 S. E., 115; Bryson v. Lumber Co., 204 N. C., 664, 169 S. E., 276; Construction Co. v. Holding Corporation, 207 N. C., 1, 175 S. E., 843; Beach v. McLean, supra; Vogh v. Geer, 171 N. C., 672, 88 S. E., 874; Re Murray, 75 A. L. R., 720; Gulf Refining Co. v. Brown, 116 A. L. R., 449; Anno. 19 A. L. R., 226, 1172, and 20 A. L. R., 686; 14 R. C. L., 65; 27 Am. Jur., 479; Henry v. Mondillo, 142 A., 230.
It appears from these authorities that the retention by the employer of the right to control and direct the manner in which the details of the work are to be executed and what the laborers shall do as the work progresses is decisive, and when this appears it is universally held that the relationship of master and servant or employer and employee is created.
Conversely, when one who, exercising an independent employment, contracts to do a piece of work according to his own judgment and methods, and without being subject to his employer except as to the result of the work, and who has the right to employ and direct the action of the workmen, independently of such employer and freed from any superior authority in him to say how the specified work shall be done or what laborers shall do as it progresses, is clearly an independent contractor.
The vital test is to be found in the fact that the employer has or has not retained the right of control or superintendence over the contractor or employee as to details.
Many cases are plainly on one side of the equation and may be readily classified as showing the relation of master and servant. Others are just as plainly to be deemed cases of independent contract.
*16But men are prone to assume the existence of one fact because of the existence of another. And so, oftentimes, the facts are not so definite or the terms of the contract are not so concise and clear as to permit ready and categorical classification without consideration of other circumstances which tend to show into which class the particular case should fall.
What, then, are the elements which ordinarily earmark a contract as one creating the relationship of employer and independent contractor? The cited cases and the authorities generally give weight and emphasis, amongst others, to the following:
The person employed (a) is engaged in an independent business, calling, or occupation; (b) is to have the independent use of his special skill, knowledge, or training in the execution of the work; (c) is doing a specified piece of work at a fixed price or for a lump sum or upon a quantitative basis; (d) is not subject to discharge because he adopts one method of doing the work rather than another; (e) is not in the regular employ of the other contracting party; (f) is free to use such assistants as he may think proper; (g) has full control over such assistants; and (h) selects his own time. Young v. Lumber Co., supra; Bryson v. Lumber Co., supra; Construction Co. v. Holding Corporation, supra; Royal v. Dodd, 177 N. C., 206, 98 S. E., 599; Midgette v. Mfg. Co., 150 N. C., 333, 64 S. E., 5; Blake v. Ferris, 5 N. Y., 48; Harrison v. Collins, 86 Pa., 153; Corbin v. The American Mills, 27 Conn., 274; Smith v. Belshaw, 89 Cal., 427; Allen v. Willard, 57 Pa., 374; Deford v. State, 30 Md., 179; Wiese v. Remme, 140 Mo., 289, 41 S. W., 797; Litts v. Risley Lumber Co., 19 A. L. R., 1147; Leet v. Block, 182 Ind., 271, 106 N. E., 373; Anno. 19 A. L. R., 243, 1210; Re Murray, supra; Mattocks v. Emerson Drug Co., 33 S. W. (2d), 142; Industrial Commission v. Hammond, 236 Pac., 1006; Morton v. Day Coal Co., 192 Iowa, 160, 180 N. W., 905; Provensano v. Div. of Industrial Accidents, 294 Pac., 71, 27 Am. Jur., 485; 14 R. C. L., 74; Anno. 20 A. L. R., 755, 766, 790; 19 A. L. R., 1168.
The presence of no particular one of these indicia is controlling. Nor is the presence of all required. They are considered along with all other circumstances to determine whether in fact there exists in the one employed that degree of independence necessary to require his classification as independent contractor rather than employee.
Thus, in applying various combinations of these tests, it has been held that the following are independent contractors:
One who undertakes to cut timber, Young v. Lumber Co., supra; Bryson v. Lumber Co., supra (a compensation case), or to cut shingles, Royal v. Dodd, 177 N. C., 206, 98 S. E., 599, for compensation on a quantitative basis; one who, being engaged in the trucking business, agrees to move a quantity of hay at a per diem for his services, Flick- *17 enger v.

Careful consideration and analysis of the facts in the light of the cited authorities leads us to the conclusion that the deceased was an independent contractor. Lovett in the beginning expressly declined to employ by the hour. Deceased and his associates were skilled electricians. They were not regularly employed by defendant, but by the Duke Power Company. They engaged extra jobs requiring their special type of skill during their “off” hours. They undertook to perform stipulated work as a whole for a specified sum, and defendant had no control over the division of the compensation. They were not required to report either before beginning or after quitting work, but were free agents as to their hours of labor. The work was to be done at their convenience, and it was left to them to decide when and where to begin and when to “kill” the electricity. They followed their own judgment as to the manner and method of setting the poles and transferring and connecting the wires. After deceased was killed his associates selected extra help to replace deceased and completed the work. Defendant could not discharge deceased or either of his associates without incurring liability for breach of contract. At the same time it had the right to insist that the work should be completed before any payment was made.
These circumstances fail to disclose that the parties to the contract contemplated or intended that the defendant or its representatives should have any right to control or direct the details of the work or what the workmen should do as the work progressed. The opposite conclusion is required.
The fact that defendant furnished a truck and two helpers and loaned a saw, shovel, and pipe poles does not tend to destroy the independency of the contract. Gay v. R. R., supra; Vogh v. Geer, supra; Beach v. McLean, supra; Litts v. Risley Lumber Co., supra; Emerson v. Fay, 94 Va., 60; Perham v. American Roofing Co., 193 Mich., 221, 159 N. W., 140; Miller v. Minnesota and N. W. Ry. Co., 76 Iowa, 655, 39 N. W., 185, 14 R. C. L., 73, 84.
The discussion as to whether the trees should be trimmed or the poles shortened took place before the work was begun and related to the general nature of the work to be performed and the general plan to be followed. While worthy of some consideration, this circumstance does not evidence the right to control the details of the work, to the extent necessary to create the relation of employer and employee. On this record it is not *19inconsistent with the conclusion that the electricians were independent ■contractors. Denny v. Burlington, supra,; Hopper v. Ordway, 157 N. C., 125, 72 S. E., 838; Johnson v. B. B., 157 N. C., 382, 72 S. E., 1057; Embler v. Lumber Go., supra; 14 R. C. L., 70; Anno. 20 A. L. R., 687; Lutenbacher v. Mitchell-Borne Gonstr. Go., 19 A. L. R., 206.
But plaintiffs insist that the rule of liberal construction -applies in cases arising under the Workmen’s Compensation Act and that this rule .should be invoked to resolve any doubt in favor of plaintiffs. In answer to this argument we need only to point out that this rule is an inter.stitial one, benefiting the injured party only in those cases where the Act applies. It cannot be invoked to determine when the Act does apply.
The doctrine of liberal construction arises out of the Act itself, and relates to cases falling within the purview of the Act. Until it is adjudicated affirmatively that the employer-employee relationship existed at the time of the accident no construction or interpretation of the Act — liberal ■or otherwise — comes within the scope of judicial inquiry.
By express terms the Act applies only where the employer-employee velationship exists. Sec. 8081 (1), Michie’s N. C. Code of 1939; G. S., :97-2; Winslow v. Carolina Conference Association, 211 N. O., 571, 191 iS. E., 403; Lee v. American Enka Gorp., 212 N. O., 455, 193 S. E., 809.
Except as to public officers the definition of “employee” contained in •the Act adds nothing to the common law meaning of the term. Nor does it encroach upon or limit the common law meaning of “independent •contractor.” Bryson v. Lumber Go., supra; Beach v. McLean, supra. The Act includes only the one and thus excludes the other. Expressio unius exclusio alterius.
Hence, in judicially determining the preliminary question of coverage the terms “employee” and “independent contractor” must be given their ■natural and ordinary meaning and effect. It must be presumed, nothing else appearing, that they are used in their accepted legal sense. Asbury ■v. Town of Albemarle, 162 N. C., 247, 78 S. E., 146; G. T. H. Corporation v. Maxwell, Gomr. of Bevenue, 212 N. C., 803, 195 S. E., 36; Bacific ■Gas and Elec. Go. v. Industrial Accident Com., 180 Cal., 497, 181 Pac., '788; 2 Sutherland Statutory Construction, 3rd Ed., pp. 438-441, 28 R. C. L., 754, 71 O. J., 341, 417.
The courts are without authority to enlarge the meaning of the terms used by the Legislature or to extend by construction its scope and intent ■so as to include persons not embraced by its terms. Garsten v. Department of Labor and Industries, 172 Wash., 51; Cornet v. City of Chattanooga, 165 Tenn., 563, 56 S. E. (2d), 742; Spivey and McGill v. Nixon, 163 Okla., 278, 21 Pac. (2d), 1049; Knudson v. Jackson, 191 Iowa, 947, 183 N. W., 391; Birmingham Post Go. v. Sturgeon, 149 So., 74; McDon- *20 aid v. Gity of New Haven, 109 Atl., 176, 10 A. L. R., 193; Mann v. City of Lynchburg, 129 Va., 454, 106 S. E., 371, 71 O. J., 417.
One who seeks to avail bimself of the Act must come within its terms and must be held to proof that he is in a class embraced in the Act. Knudson v. Jackson, supra; Bingham Gity Corporation v. Industrial Commission of Utah, 243 Pac., 113 ; Spivey and McGill v. Nixon, supra; Mobley v. Brown, 151 Okla., 167, 83 A. L. R., 1014; Hamilton v. Randall, 276 Pac., 705; Harris v. Oklahoma Natural Gas Co., 216 Pac., 116; El Reno Broom Co. v. Roberts, 281 Pac., 273. See also 71 O. J., 341.
As plaintiffs have failed to show that they are dependents of an employee of defendant Board who suffered death by accident arising out of and in the course of his employment the judgment below must be
