delivered the opinion of the court:
Upon the trial of this case in the circuit court before the court without a jury, the finding and judgment were in favor of the present appellant, the defendant below. Upon appeal to the Appellate Court, that court reversed *417the judgment in favor of the appellant, and entered an original judgment in favor of the present appellees, who were the plaintiffs below. The judgment of the Appellate Court, after the usual formal recital, was as follows: “Therefore it is considered by the court that for that error and others in the record and proceedings aforesaid, the judgment of the circuit court of Cook county in this behalf rendered be reversed, annulled and set aside and wholly for nothing esteemed. The court finds that appellants’ vessels were delayed by the fault of appellee in all forty-six (46) days, and appellants suffered damages for such delay to the amount of three thousand seven hundred twenty-seven and 60/100 ($3727.50) dollars, and it is further considered by the court that the said appellants recover of and from the said appellee the sum of three thousand seven hundred twenty-seven and 50/100 (R3727.50) dollars, and their costs by them in this behalf expended, to be taxed, and that they have execution therefor.”
The Appellate Court has recited in its final judgment the facts, as found by it, and has, therefore, made a finding of the facts concerning the matter in controversy in the suit different from the finding of the circuit court. This being so, the judgment of the Appellate Court is final and conclusive as to the matters of fact in controversy. The facts, so found by the Appellate Court and incorporated in its final judgment, must be the ultimate facts as set up in the pleadings, and not the merely subordinate or evidentiary facts which contribute to the establishment of the ultimate fact or facts. (Brown v. City of Aurora, 109 Ill. 165; Travelers' Ins. Co. v. Pulling, 159 id. 603; Davis v. Chicago Edison Co. 195 id. 31; Hogan v. Gity of Chicago, 168 id. 551). The question then is, whether the judgment of the Appellate Court is warranted by its finding of facts. (Bown of Bristol v. Town of Fox, 159 111. 500; Hogan v. City of Chicago, supra; Davis v. Chicago Edison Go. supra; Manistee Lumber Go. v. Union Nat. Bank, 143 111. 490).

*418The appellant here contends that the finding of the Appellate Court does not sustain its judgment, upon the alleged ground that it does not make a finding upon all the issues made by the pleadings, and raised by evidence properly admissible under the pleadings. In support of this contention, cases are referred to, holding that the finding of the Appellate Court, in order to support its judgment, must include every material issue submitted to the trial court. (Commercial Ins. Co. v. Scammon, 123 Ill. 601; Neer v. Illinois Central Railroad Co. 138 id. 29; Hawk v. Chicago, Burlington and Northern Railroad Go. id. 37; Hogan v. Gity of Ghicago, supra; Hayes v. Massachusetts Mutual Life Ins. Go. 125 111. 626). It is said that one of the issues was, whether the parties made the contract offered in' evidence, and that the judgment makes no finding upon this issue. In reply to this it may be said, that there was no controversy between the parties as to the execution of the written contract, and, therefore, a finding upon that subject was unnecessary. It is also said that issues were made, upon the trial below, upon the following questions: whether there was a breach of the contract by appellant; whether the appellees suffered damages, and if so, to what amount, by reason of such breach; whether there was a waiver of the alleged breaches, or satisfaction of the damages, by the acts and conduct of the parties; and whether the claim of appellees is barred by the Statute of Limitations.
' It is conceded that the finding, embodied in the judgment, states the amount of damages suffered by appellees; and very clearly it also recites that “appellants (appellees here) suffered damages” for the delay alleged in the declaration. Embodied in the finding, “that the appellants’ vessels were delayed by the fault of appellee in all forty-six (46) days,” is the finding that there was a breach of the contract by the present appellant. The contract was, that the vessels of appellees should have “quick dispatch in loading and unloading.” This involved *419the guaranty, or agreement on the part of the present appellant, that there should be no unreasonable delay in the loading of the vessels at the points from which the ore was to be shipped, or in the unloading of the vessels at the destination of the cargoes in South Chicago. Unnecessary and unreasonable delay in this regard, if caused by the present appellant, was therefore a violation of the contract; and, consequently, the finding of facts, embodied in the judgment, amounts substantially to a statement that there was a breach of the contract. The finding of the facts in the judgment is also a finding that there was no waiver of the alleged breaches, because, if there had been a waiver of the breaches, appellees could not be entitled to any amount on account of damages. But, upon an examination of the testimony, we do not find that any such issue as a question of waiver is raised by the proofs in the case. There may have been a question of law as to the existence of a waiver, arising out of some of the documentary evidence, which will be referred to hereafter.
As to the issue, whether the claim of appellees was barred by the Statute of Limitations, that issue arose upon a demurrer to a replication to the Statute of Limitations as filed to the matters and things set up in the additional counts of the declaration. Whether or not the trial court erred in overruling the demurrer to the replication is immaterial, and, if there was error in this respect, it was harmless error. The written contract, upon which the appellees sought to recover under the special count of their declaration, was properly introduced in evidence, and, with the proof of its breach, sustains the judgment of the Appellate Court,, irrespective of the question whether the cause of action, set up in the additional counts, was barred by the Statute of Limitations, or not. We are, therefore, of the opinion that, while the finding of facts in the judgment of the Appellate Court is not as full and explicit as it might have *420been, yet it includes the material issues submitted to the trial court, and substantially states the ultimate facts, as set up in the pleadings.
Appellant insists that the finding, set forth in the judgment of the Appellate Court, is not responsive to the issues, because of the use of the word “fault” in the finding of facts. It is said that, because of the use of this word, the finding is based upon tort when the action is in assumpsit. The word, “fault,” as here used, has not the meaning, which the word has, when used to designate the wrong committed in an action of tort. It is merely a statement that the appellant failed to furnish quick dispatch in loading and unloading as called for by the contract. By saying that the vessels of the appellees were delayed by the fault of the appellant, the Appellate Court in its judgment merely says that the. vessels of the plaintiffs were delayed by reason of the failure of the defendant to give them quick dispatch in loading and unloading, as required by the provisions of the contract.
It is furthermore contended by the appellant, that errors of law, prejudicial to appellant, intervened in the trial court, and that these errors were such as necessarily affected and influenced the finding of the Appellate Court. The position, taken by appellant’s counsel upon this branch of the case, is that the appellant did not and could not assign error in the Appellate Court upon the rulings against it, made in the trial court, because the final judgment of the trial court was entirely in favor of the appellant, and it was not, therefore, in a position to complain of that judgment; that it could not complain of rulings against it, which were harmless, so long as the final judgment was in its favor; that here, however, the situation is changed, and the rulings upon preliminary questions, as well as the final judgment, are complained of;' that appellant is entitled to a review by this court of such rulings, made by the trial court to the prejudice of appellant, as were materially erroneous.
*421This contention of appellant seems.to be sustained by the holding of this court in Seeberger v. McCormick, 178 111. 407. In that case the facts were similar to the facts here. - There the jury was waived and the cause submitted for trial to the court without a jury. There, propositions were asked by the plaintiff to be held as law in the decision of the case, but the court refused all of them; no propositions were asked by the defendants; and the court rendered judgment for the defendants; upon appeal by the plaintiff, the Appellate Court reversed the judgment and entered judgment against the defendants, and assessed the damag'es at §22,208.33. In the Seeberger case it was held that, where the Appellate Court, although agreeing with the trial court’s conclusions from stipulated facts, reverses a judgment for defendant in a case tried without a jury and enters judgment on plaintiff’s demand, the defendant, though he submitted no propositions of law below, may in the Supreme Court assign as an error of law that the Appellate Court has, in effect, upheld plaintiff’s refused propositions of law; and it was also there held that, where the Appellate Court reverses a judgment for the defendant in a case tried without a jury on agreed facts, and enters judgment on plaintiff’s demand, having drawn different conclusions from the agreed facts from those reached by the trial court, the question is presented to this court from the record itself, independently of the submission of propositions of law in the trial court, whether the facts found by the Appellate Court are sufficient in law to sustain its judgment.
Relying upon the rule, laid down in Seeberger v. McGormiclc, supra, the appellant insists that the findings and judgment of the Appellate Court have been affected or influenced by certain alleged errors committed by the trial court. The first error, claimed to have been committed by the trial court, is the admission in evidence of the contract sued upon. It is said that there was a fatal variance between the contract, set forth in the declara*422tion, and the written contract set forth in the statement preceding this opinion. Upon referring to the record we find that, while appellant objected to the introduction of the contract on the ground of a variance, the nature and character of the variance were not stated. If, however, it should be admitted that the objection sufficiently indicated the nature of the variance, we do not think that, on this account, the court erred in admitting the contract in evidence. The contract recited as follows: “Ore to be freighted between the opening of navigation and the 30th of October next, or as we may agree.” The alleged variance is that the contract, set out in the special count of the declaration, was to the effect that the defendant agreed to commence furnishing ore to plaintiffs for transportation at the opening of navigation for the season of 1891, while, as it is insisted, the contract em-. bodied in the letters, offered in evidence, was merely to furnish the ore at some time between the opening of navigation and the 30th day of October. This objection is not well taken, because it ignores the words “or as we may agree.” The special count of the declaration correctly set forth the proposition as to the transportation of the■ ore and its acceptance. The further allegation, that there was a failure to furnish the ore for transportation at the opening of the season of navigation, was justified by the agreement made in pursuance of the words “or as we may agree.”
It is further claimed that the trial court erred to the prejudice of appellant in overruling its demurrer to the plaintiffs’ replication to its plea of the Statute of Limitations. It necessarily follows from the conclusion, that there was no variance between the special count and the contract offered in evidence, that the action of the trial court in overruling defendant’s demurrer to plaintiffs’ replication was harmless error.
It is also insisted by the appellant that the court below erred in permitting two witnesses, named Hausler *423and Massey, to use certain memoranda to refresh their memories while giving their testimony. A witness, in giving testimony, may make use of a memorandum to refresh his memory. He may also make use of a copy of an original memorandum to refresh his memory, when it appears that the copy so used is an exact copy, and that the original has been lost. While, however, it is true that a witness may use the memorandum to refresh his memory, he must be able to say, after having referred to the memorandum to refresh his recollection, that he remembers the facts about which he has testified. (Chicago and Alton Railroad Co. v. Adler, 56 Ill. 344). Under the rule thus announced, the testimony of these witnesses was not objectionable. As to one of them, no exception was taken to the ruling of the court admitting his testimony. As to the other, exception was taken. But whether or not the court erred in permitting the witnesses to testify from the memoranda in question is immaterial, for the reason that there was other testimony introduced, which established the facts testified to by the witnesses from their memoranda, independently and outside of the testimony of such witnesses. Where a case is tried before the court without a jury, the admission of incompetent testimony will not justify a reversal of the judgment, if sufficient competent testimony was introduced to authorize the finding made by the court. {Schroeder v. Harvey, 75 111. 638; Pardridge v. Ryan, 134 id. 247).
Among the propositions of. law submitted by the appellees to the trial court, which were refused by that court, was one requesting the court to hold that the delivery of the cargoes by the appellees to the appellant, and the acceptance by the appellees of the freight for carrying the same, did not constitute a waiver of any claim that appellees may have had at the time against the appellant, under the contract in evidence, for the detention of the ships with such cargoes on board, and before the same were fully discharged. By refusing this *424proposition,-as is claimed by the appellant, the trial court held substantially that the delivery of the cargoes and acceptance of the freight amounted to a waiver of any claim for delay in the loading and unloading of the ves- . seis. It is said that the Appellate Court must have differed with the trial court upon this subject, and must have held to the view that the delivery of the cargoes and the acceptance of freight did not amount to a waiver of the claim for detention of the vessels. If such was the holding of the Appellate Court, it would seem to have been correct, as the authorities are that the delivery of cargo and collection of freight money is not a waiver of claim for demurrage. (Durchman v. Dunn, 101 Fed. Rep. 606; Same v. Same, 106 id. 950; Fire Ins. Ass. v. Wickham, 141 U. S. 564; Ryan v. Ward, 48 1ST. Y. 204; Garfield and P. Goal Go.v.Fitchburg Railroad Go. 166 Mass. 119). Evidently, the Appellate Court here reversed the judgment of the trial court on findings of fact, and not on account of any erroneous rulings on any questions of law that arose in the trial. Otherwise, the Appellate Court would have remanded the cause for a new trial. (Siddall v. Jansen, 143 111. 537; Busenbark v. Saul, 184 id. 343; Supple v. Agnew, 191 id. 439). The rule, requiring the remandment of a cause by the Appellate Court when the judgment is reversed on account of erroneous rulings of the trial court on questions of law, need not be enforced, except in cases where the error of the trial court might be obviated on another trial. In such case, it would be the duty of the Appellate Court to remand the cause for another trial. (Senger v. Town of Harvard, 147 111. 304; Hogan v.City of Chicago, supra). Where the trial has been by agreement before the court without a jury, resulting in a judgment for the defendant, the Appellate Court may not only reverse, but may also render judgment for the plaintiff, if the law, as applied to the facts found by that court necessitates such a judgment, and if it can be ascertained from the facts so found what judgment ought to have been rendered by *425the court below. (Manistee Lumber GC.v. Union Nat. Bank, 143 111. 490). The result could not be different in the present case, if the cause should be remanded to the trial court because of the error of the trial court in holding that the delivery of the cargoes and the acceptance of freight amounted to a waiver. Upon another trial, the trial court would be obliged to hold that there was no waiver upon the face of the bills of lading and receipts for freight attached thereto. There being no waiver, judgment under the facts would be for the present appellees upon another trial, and, therefore, a remandment by the Appellate Court was unnecessary. The Appellate Court was justified in here entering the judgment, which it did enter, because it was easily ascertainable from the facts found what judgment ought to be rendered by the court below.
Accordingly, the judgment of the Appellate Court is affirmed.
Judgment affirmed.
