after making the foregoing statement of facts, delivered the opinion of the court.

The defendant in error, as a witness in his own behalf, was asked by his counsel the following question:

An objection to this question was overruled by the court, and the witness answered:

It is objected to this evidence that the shipment was made under a special contract, which was complete in itself, and was a contract simply to transport stock; that this evidence tended to show a custom making another and a different contract for the transportation of the stock by an independent train, and it is contended that this could not be done. The objection cannot be sustained. The evidence did not tend to establish a new contract, or to change or modify the terms of the written contract. The contract was silent as to time and manner of performance, and- the evidence was properly introduced to inform the court and jury as to the custom prevailing with respect to the character of transportation the parties liad in view when they made the contract. The contract did not say whether the cars in which the cattle were loaded were to be attached to a through freight train or to a way freight train, or whether the cars were to be hauled as an independent train. Which of these methods was the carrier to furnish? The presumption was that the parties to the contract understood that the cattle were to be transported in the way that similar freight in similar quantities was being transported, and the evidence objected to, as well as other evidence not objected to, relating to the method of transportation, was introduced for the purpose of establishing that fact, and was admissible for that purpose. Robinson v. United States, *995 13 Wall. 363 , 20 L. Ed. 653 . A custom or usage known to the shipper, as to the manner or method of transportation, will be binding as a part of the contract when not contrary to its terms. 6 Cyc. 428.

It was also objected that the court instructed the jury that it was entitled to take into consideration the evidence relating to the question whether cattle being transported in a number greater than ten car loads were or were not hauled by regular freight trains, or trains gotten up specially for the purpose of transporting such cattle. It is contended, first, that the plaintiff was only entitled to transportation as an independent train when demanded, and it is claimed that the testimony shows that when such transportation was demanded it was furnished; and, second, that the evidence was insufficient to establish a custom that 10 cars and upwards constituted a stock train. It is true, the plaintiff testified that it was “customary, when asked, to give power for ten cars or upwards to the capacity of the power, and transport it as a separate train, when demanded.” This answer, standing alone, is not very clear. But he made his meaning clear in a subsequent statement. He said: “We always expect it when shipping either in or out. We collect a train load, and were entitled to a stock train. If we had ten cars or more, we generally get separate power for them.” What the witness evidently meant was that, when transportation was asked for 10 car loads or upwards, it was customary to transport the shipment as a separate train. James E. Farnham, who had been in the cattle business in Montana since 1883, and for the last 12 years had shipped most of the cattle for his company, testified: “If we have a train load, we have power of our own. A train load is from ten cars up.” This evidence was sufficient to justify the instructions given by the court. It also disposes of the objection that the court refused to instruct the jury that no sufficient proof had been given to establish a custom under which the plaintiff was entitled to have the cattle transported as an independent train, with independent power; and it disposes of the further objection that the court refused to instruct the jury that the plaintiff, having failed to demand an independent train with independent power from Fargo to Mandan, had waived his right thereto.

The plaintiff testified that the train stopped at Richardton; he did not know why. He asked the conductor: “Why don’t you get over the road?” He said: “I can’t get anywhere with this dummy. They should have known better than to send it out this kind of weather.” The defendant moved to strike out this answer, because, assuming he referred to the engine or power, the conductor’s statement was not admissible to bind the defendant. The motion was denied, and the defendant excepted. The question at issue in the case was whether there was any unreasonable delay in moving the train containing the cattle. The defendant was charged with negligence in attaching plaintiff’s cars to a train that proceeded at a slow rate of speed and stopped at many stations. The defendant denied that it had been guilty of the negligence charged. The statement of the conductor was made in the midst of the act com *996 plained of, reflecting light upon its quality and character, and under the general rule was part of the res gestse. As said by Mr. Justice Cooley in Sisson v. Cleveland R. Co., 14 Mich. 489 , 90 Am. Dec. 252 :

The declaration of a servant while engaged in enforcing the regulations of a steamboat company concerning passengers, with respect to which complaint was made that the regulation was being enforced with unnecessary or cruel severity, was held to constitute a part of the res gestse. New Jersey Steamboat Co. v. Brackett, 121 U. S. 637, 649 , 7 Sup. Ct. 1039, 30 L. Ed. 1049 . Where a railroad employé has been injured by the movement of cars about which he was at work, statements of the conductor of the train, made almost immediately, and while the cars were moving or had just stopped, and while the injured man was bleeding from the injury at that moment received, describing his own part in bringing about the motion that effected the injury, were held to be admissible as part of the res gestse. Peirce v. Van Dusen, 78 Fed. 693, 706 , 24 C. C. A. 280 (Circuit Court of Appeals, Sixth Circuit, opinion by Mr. Justice Harlan). A conversation of a conductor with a passenger who expressed fear of a fellow passenger, as to the latter’s sanity, being in discharge of the conductor’s duty to the passenger, was held admissible as part of the res gestse in an action against the railroad company for the killing, shortly after such conversation, of another passenger by the person whose sanity was questioned. St. Louis, I. M. & S. Ry. Co. v. Greenthal, 77 Fed. 150, 152 , 23 C. C. A. 100 (Circuit Court of Appeals, Eighth Circuit, opinion by Judge Caldwell). These and other similar cases indicate the scope of the rule as established by the courts,- under which we think the evidence was properly admitted.

The court instructed the jury that:

The defendant took an exception to this instruction, and contends that it is not a correct statement of the law applicable to this case, under the terms of the special contract. ■ The contract provides that:

We are unable to discover how this provision of the contract changes any rule of evidence otherwise applicable to the case. .The instruction was taken from the case of Scott v. The London & St. Catherine’s Dock Co., 3 Hurlstone & Cottman, 596. The plain *997 tiff in that case was injured by bags of sugar falling from a crane in which they were lowered to the ground from a warehouse by the defendant. The court said:

This doctrine was held to be applicable to a common carrier in the transportation of flour in Rintoul v. New York Cent. & H. R. Co. (C. C.) 17 Fed. 905, 907 , and is stated to be the law in Shearman & Redfield on Negligence (5th Ed.) § 59. We think the instruction, taken in connection with other instructions given by the court, stated correctly a rule of evidence applicable to the case.

The court refused to give the following instruction requested by the defendant:

The defendant contends that it was entitled to this instruction by reason of an allegation contained in the complaint “that had the said cars been made into an independent train and furnished with sufficient independent power out of the city of Fargo, and, if such train had proceeded with reasonable speed, it would have arrived at the town of Fallon before the snowstorm, or before it had prevailed a sufficient length of time to cause any injury to the cattle,” and the evidence of the train dispatcher, drawn out on cross-examination, that, had the train left certain points on time, delays at other points would not have occurred. It is further contended by the defendant that plaintiff’s theory was that, though the delay on account of the storm was in and of itself inevitable, the defendant was responsible for its consequences, if it might not have happened but for a previous delay for which defendant was responsible, and that as this theory is in conflict with the law upon this subject as declared by the Supreme Court of the United States in Railroad Company v. Reeves, 10 Wall. 176, 189 , 19 L. Ed. 909 , and in St. Louis, etc., Ry. v. Commercial Ins. Co., 139 U. S. 223, 236, 11 Sup. Ct. 554, 35 L. Ed. 154 , the instruction requested should therefore have been given. It is a sufficient answer to this contention to say that, whatever may have been the theory of the plaintiff as to the liability of the defendant for a delay following a previous delay for which the defendant was responsible, the theory of the court was in accordance with the decisions of the Supreme Court, as appears from the instructions given as requested by the defendant, as follows:

It is assigned as error that upon the conclusion of the evidence the court refused to instruct the jury to find for the defendant. Among the reasons urged why this instruction should have been given is a provision of the contract—

The damages claimed were alleged to have been sustained between May 1, and May 4, 1899. This action was originally commenced in the district court of Montana, in and for the county of Custer, on September 5, 1899, or 122 days after the damages occurred. It is claimed by the plaintiff in error (defendant in the court below) that this limitation is not forbidden by the law of Minnesota, where the contract was made, and should be enforced. The contract was to be executed partly in Minnesota and partly in North Dakota and Montana. In the last'two states the limitation is void by statutory prohibition. Rev. Codes N. D., 1899, § 3925; Civ. Code Mont. § 2245. The latter Code provides:

The delivery of the cattle was to be made in Montana. The plaintiff was a citizen of Montana, and the suit was brought in Montana. The breach of the contract occurred in North Dakota and Montana. The limitation in the contract is contrary to the policy of Montana, as expressed in its law, and could not be enforced in that state. This is an exception to the general rule that a contract valid and binding in the state where made will be enforced in another state. Chicago, B. & Q. R. Co. v. Gardiner, 51 Neb. 70 , 70 N. W. 508 . The rule applicable to this case is: A contract valid elsewhere will not be enforced if it is condemned by positive law, or is inconsistent with the public policy of the country, the aid of *999 whose tribunals is invoked for the purpose of giving it effect. Union Locomotive Exp. Co. v. Erie Ry. Co., 37 N. J. Law, 23; Thompson v. Taylor (N. J. Sup.) 46 Atl. 567 ; The Kensington, 183 U. S. 263, 269 , 22 Sup. Ct. 102, 46 L. Ed. 190 . This suit was brought in the state court of the state of Montana, and by the defendant removed to the United States Circuit Court for the District of Montana. In the state court the plaintiff was entitled to the benefit of the prohibition against the stipulation or condition in the contract limiting the time within which plaintiff might enforce his rights by legal proceedings, and the defendant could not, by removing the case to the federal court on the ground that it was a citizen of another state, deprive the complainant of such a substantive right. Missouri, K. & T. Trust Co. v. Krumseig, 172 U. S. 351, 358 , 19 Sup. Ct. 179, 43 L. Ed. 474 . This provision of the contract did .not entitle the defendant to an instruction to the jury to find in its favor. The other grounds urged for such an instruction do not appear to have any substantial grounds, and need not be discussed.

Finding no error in the record, the judgment of the Circuit Court is affirmed.
