opinion: GILBERT, Circuit Judge
  (after stating the facts as above). The defendant assigns error to the denial of its motion for án instructed verdict in its favor, and it contends that the evidence failed to show the existence of a contract between the parties, and that, if there was a contract, it contained the condition that the plaintiff ship the rails from Philadelphia on March 15, 1921, and that the failure to comply with that condition justified the defendant in canceling the order as it did on June 14, 1921. The plaintiff had local agents in San Francisco. After negotiations with those agents, the defendant wrote to the plaintiff on February 23, 1921: “We have this day purchased from you.for 600 gross tons new first quality steel rails of the following specifications, * * * at $61 per gross ton of 2,240 pounds. * * * Terms: Sight draft against shipping documents attached, c. i. f. San Francisco. This is to acknowledge same. Please send me your confirmation.”
  ■ On March 2, the plaintiff answered that the order of February 23 had been accepted at the precise, terms and on the conditions herein set forth (repeating the specifications which had been contained in the letter of the defendant), that the acceptance of the order was subject to conditions mentioned on the back of the acceptance., and adding: “unless advice to the contrary is received promptly, this order shall be considered satisfactory in all details.” The “conditions” so referred to concerned the shipment and delays therein, and the exclusion of liability if strike or accident or interruptions of transportation beyond the control of the seller should intervene to prevent the carrying out of the terms of the' agreement.
  It is urged by the defendant that no response was sent to that letter, that the terms and conditions therein inserted were never accepted by the defendant, and that the minds of the parties never met upon the contract which the plaintiff sued upon. To this-it is said that the additional conditions inserted in the plaintiff’s final letter were of but minor importance, ■ and the plaintiff’s silence, together with its subsequent conduct in treating the correspondence as constituting an existing contract, must be deemed assent thereto. It is true that a mere offer made to another, does not become an agreement merely from the fact that the person-to whom it is made makes no reply, even though the offer states that silence will be taken for consent; but where, as in this case, the contract is expressed by letters) the court has the right to look to the construction which the parties place thereon. McKell v. Chesapeake & O. Ry. Co. (C. C. A.) 175 F. 321, 20 Ann. Cas. 1097; Det Forenede, etc., Aktieselkab v. Eddy (D. C.) 293 F. 82, 87; American Lumber & Mfg. Co. v. Atlantic Mill & Lumber Co. (C. C. A.) 290 F. 632.
  Here it is shown that on April 15, 1921, about six weeks after the date of the plaintiff’s letter, the defendant wrote to the plaintiff that it had heard from its bank that the plaintiff’s drafts had arrived, and that therein the defendant had been charged up with war tax and state toll on the shipment. To that letter the plaintiff made answer on April 22, 1921, that those charges had been added through a misunderstanding, and that the bank had been instructed to reduce the aggregate of the drafts to adjust the error. That correspondence clearly indicates that on April 15, 1921, the minds of the parties had met, and that the defendant had accepted- and acquiesced in all the terms of the contract, with the conditions expressed by the defendant, and was asserting a right thereunder to be relieved of charges which were not justified by the agreement. Acceptance of the terms of the plaintiff’s letter of March 2, 1921, is shown also by the defendant’s letter to the plaintiff of June 14, 1921, which complains of the fact that, whereas, the contract required that the rails should leave Philadelphia on or about March 15, and arrive at San Francisco 35 days thereafter, they had not yet arrived; “therefore kindly consider our order on this material canceled.”
  Nor can we assent to the defendant’s contention that, if there was a contract, there was failure of performance, in that the vessel did not sail from Philadelphia until three or four weeks after March 15, 1921. It is admitted that the steel was loaded on board the Dunsyre on or before March 15, and this, we think, establishes shipment within the time required by the contract. “A seller who agrees to ship the goods sold to the buyer on or before a certain day complies with his contract when he delivers the goods on such date to a carrier for transportation on a regular line of transportation between the point of shipment and destination. He is under no obligation to ascertain that the carrier moves the goods toward their destination on the day specified.” 23 R. C. L. 1372; Pedro Mora y Ledon v. Havemeyer, 121 N. Y. 179, 24 N. E. 297, 8 L. R. A. 245; Busk v. Spence, 4 Camp. 329; Clark v. Lindsay, 19 Mont. 1, 47 P. 102, 61 Am. St. Rep. 479; Bowers v. J. B. Worth Co., 129 N. C. 36, 39, 39 S. E. 635; Andersen, Meyer & Co. v. Northwest Trading Co., 115 Wash. 39, 196 P. 630; Schwann v. Clark, 9 Misc. Rep. 117, 29 N. Y. S. 289.
  The defendant contends that there is absence both of allegation and proof of performance or tender of the rails on the plaintiff’s part. But we find that the complaint alleges performance by the plaintiff, and we hold that, in view of the admitted facts, there was no necessity to prove a tender of the rails. It was stipulated that the invoices were sent, together with bills of lading attached to the drafts, through a local San Francisco bank for collection, and that presentation was made to the defendant, and payment was by it refused, for the reason that war tax and state tolls had been added to the amount of the drafts. After that error was corrected,/payment was refused on the ground that the vessel had been delayed in sailing from Baltimore, but payment was promised as soon as news should come that the vessel had cleared the canal. When such news did come, payment was refused until the rails should arrive at San Francisco. But on June. 14, 1920, before they arrived, the defendant wrote to the plaintiff, canceling its order. “If the buyer, before the time for delivery has arrived, notifies the seller that he will not accept delivery, the seller is excused from making a tender of the goods at the time and place fixed by the contract.” 23 R. C. L. 1416. Section 1440 of the California Civil Code is in harmony with the text so quoted, as also are the decisions of the courts of that state. Passow & Sons v. Harris, 29 Cal. App. 559, 156 P. 997; Scribner v. Schenkel, 128 Cal. 250, 60 P. 860; Walker v. Harbor Business Blocks Co., 181 Cal. 773, 186 P. 356.
  The defendant’s contention that there was absence of proof of damage to the plaintiff is not sustainable. It is admitted that the measure of damages in such a case is the excess, if any, of the amount due from the buyer over the value to the seller, together with the expenses properly incurred by the latter in carrying the property to market, in excess of what would have been incurred, had the buyer accepted the goods. It is also admitted that the value of the property to the seller is the price which he could obtain therefor in the market nearest the place at which it should have been accepted by the buyer, and at such time after the breach of the contract as would have sufficed the seller with reasonable diligence to effect a resale. It was stipulated that the shipment was 631 tons of rails, including joints. It was in evidence that the rails were not of the type used for railways, but wore much lighter in weight, and wor'e such as were used generally in mines, lumberyards, and industrial tracks, and that a shipment of 631 tons of them was extremely large. A witness testified that 1,000 tons of such rails would meet the requirements of the entire Pacific Coast from Seattle to Los Angeles for a period of a year.
  As showing that the market price of the rails was higher than the contract price at the time of the breach, the defendant points to certain sales that were made. But those sales were of small lots, sold at retail, and they have little value in detejmining what was the market value of the rails when offered in wholesale lots. There was evidence that at San Francisco the market value in May, June, July, and August, 1921, was from $45 to $50 per gross ton. But the defendant complains that no proof was offered of market price on April 13, 1921, the date when it says the contract was breached. But there was no breach in the defendant’s refusal on April 13 to pay the drafts on account of certain excess charges therein. There was no breach until June 14, 1921, when- the defendant repudiated the contract. Up to that time it was making promises of payment. In brief, there was evidence to the effect that the local market value was about $15 less than the contract price, and that the cost of carrying the rails from the ship to the market place was from $2.50 to $3 per ton.
  But the defendant contends that evidence of a sale made in July, 1922, more than a year after the arrival of the rails in San Francisco, at $32.50 per gross ton, was inadmissible as too remote in point of time, citing Strait v. Wilkins, 23 Cal. App. 774, 139 P. 911, a case which holds that a court is required, in the exereisé of a sound discretion, to limit the proof of market value to a period reasonably proximate to that of the date of the breach. In the present case there was evidence that 1,00Q tons of that class of rails would meet the requirements of the entire Pacific Coast for one year, and in view of the fact that 631 tons were to be disposed of in the San Francisco market, and it took the plaintiff a year to sell them, we are not convinced that discretion Was abused in admitting testimony of market value at the date of the last sale which was made.
  In Montgomery v. Sayre, 100 Cal. 182, 34 P. 646, 38 Am. St. Rep. 271, it was held that evidence of value for short periods before and after the date in question might be allowed in the discretion of the court. The court said that the jury had a right to consider the character and situation of the property and the usual methods by which sales of such property were effected. In Herdan v. Hanson, 182 Cal. 538, 543, 189 P. 440, it was held that the admission of evidence of value of merchandise at some months prior to the date of the execution of the contract was largely within the discretion of the trial court, and such is the general law as to the right of the seller. “He may resell at any time and in any state of the market, and the fact that he refrains from selling them for several months on a falling market will not prevent him from recovering in an action against the buyer for the deficiency.” 24 R. C. L. 112.
  The judgment is- affirmed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "trade". Your task is to determine what subcategory of business best describes this litigant.
