In July, 1920, the parties entered into an agreement by which the plaintiff was to sell and the defendant to buy three carloads daily of “ R/M bituminous ” coal from July 21, 1920, to March 31, 1921. The price per ton was $3.85 f. o. b. cars at the mine, subject to variations in rates of wages of mine labor. The defendant was to furnish cars for loading. The plaintiff was to ship the coal to places designated by the buyer, “ shipments . . . [to] be made as nearly as practicable in equal monthly quantities,” payments to be made not later than the twenty-fifth day of each month “ for coal received during the preceding month.” On January 11, 1921, the defendant wrote the plaintiff instructing it to “ cease further shipments.” No coal was shipped after January 14, the defendant supplying no cars after that date. There was evidence that all the coal shipped complied with the contract. There also was *505evidence upon which the jury could have found that the defendant was justified in terminating the contract. After the defendant’s refusal to receive any coal under the contract, the plaintiff requested the defendant to reconsider its action and urged it to continue with the contract. The plaintiff continued production selling at the market price to persons other than the defendant.
The cost of producing coal from January 15, 1921, to April 1, 1921, was $3.10 per ton. The market price was $2 per ton. It was agreed that the contract price during that time was $4.25 per ton; that the contents of a car was fifty tons. There was evidence that sixty-five working days remained; that the plaintiff was ready and able to ship three cars a day to the defendant during this period. It was agreed that the cost of shutting down the mine would have been $2,500.
The action was in contract, for the breach of the agreement; the jury finding for the plaintiff in the sum of $12,-606.58 if the plaintiff should be limited to the difference between the contract price and the cost of production, and in the sum of $24,665.06 if the plaintiff could recover the difference between the contract price and the market price. A verdict was directed in the sum of $12,606.58, the plaintiff excepting to the refusal to rule that the measure of damages was the difference between the contract price and the market price. The case was then reported to this court. It did not appear that the item of $2,500, the cost of shutting down the mine, entered into either finding of the jury.
By the contract, which was signed by the plaintiff in New York and by the defendant in Connecticut, coal was to be delivered on cars in Pennsylvania, and shipments were to be made in New Jersey and New York. It was agreed that the uniform sales act was in force in all these States; and the statutes of these States were in evidence. No decisions of these States were introduced in evidence. The interpretation of the statute is therefore a matter of law for the court. See Wylie v. Cotter, 170 Mass. 356, 357; Electric Welding Co. Ltd. v. Prince, 200 Mass. 386, 390. G. L. c. 106, § 53, giving the seller a remedy in damages if the *506buyer refuses to take the goods, corresponds to the foreign laws in evidence, namely, Penn. Laws 1915, c. 241, § 64. New Jersey Laws 1907, c. 132, § 64. New York Laws 1911, c. 571, § 145. Conn. Laws 1907, c. 212, § 64. Subsection (2) § 53, G. L. c. 106, enacts that the measure of damages “ shall be the estimated loss directly and naturally resulting, in the ordinary course of events, from the buyer’s breach of contract.” Subsection 3 provides, where there is an available market for the goods in question, that the rule of damages, in the absence of “ special circumstances showing proximate damage of a greater amount,” is the difference between the contract price and market price “ at the time when the goods ought to have been accepted, or, if no time was fixed for acceptance, then at the time of the refusal to accept.”
The plaintiff was entitled to the profits of the contract. Subsection 3 of the sales act governs the case. There was an available market for the coal, and the plaintiff could recover the difference between the price called for in the contract and the market or current price at the time of the breach of the contract. Moffat v. Davitt, 200 Mass. 452. Barrie v. Quinby, 206 Mass. 259, 267, 268. Hall v. Paine, 224 Mass. 62, 63, 64.
Subsection 4 of the statute, providing that if the buyer repudiates the contract, while labor or expense is necessary to the seller to fulfil contract, the buyer shall be liable “ for no greater damages than the seller would have suffered if he did nothing toward carrying out the contract . . . after receiving notice of the buyer’s repudiation,” is not applicable to the case at bar. The commodity to be sold by the plaintiff to the defendant under the contract was a staple product for which there was an available and open market. The plaintiff was not called on to manufacture an article for the defendant which had no true market value, and where he might be called upon to mitigate the damages. See Hinckley v. Pittsburgh Bessemer Steel Co. 121 U. S. 264; W. R. Grace & Co. v. Nagle, 275 Fed. Rep. 343; Spencer Kellog & Sons, Inc. v. Providence Churning Co. 45 R. I. 180. Williston on Sales § 589.
*507The plaintiff dealt with the defendant for the sale of goods sold in the open market; he is entitled to the fruits of his contract and to be placed in as good a position as he would have been, if the defendant had fulfilled his contract. See Leavitt v. Fiberloid Co. 196 Mass. 440, 445.
A verdict could not have been directed for the defendant. There was evidence that the plaintiff had in all respects complied with the contract. The defendant’s motion for a directed verdict was denied properly. The defendant asked for certain requests, but no exception was taken to the refusal to give them, before the charge to the jury. Rule 45 of the Superior Court (1923).
The judge’s charge is not reported and no exception appears to have been taken to it; he supposed that the only question reserved related to damages; and the conversation between counsel and the judge at the close of the charge shows this to be so. The questions now argued by the defendant relate to the matter of an anticipatory breach, and that the plaintiff’s action was prematurely brought. There is nothing in these contentions: the action was not brought until the time for full performance had passed. Moreover, the defendant’s breach went to the essence of the contract; it was a material breach, occurring after performance had begun under the contract, and for this breach the plaintiff could have sued at once and recovered the entire damages. Speirs v. Union Drop Forge Co. 180 Mass. 87, 91, 92. Barrie v. Quinby, 206 Mass. 259, 267.
The plaintiff is entitled to the larger sum based on the difference between the contract and the market price, and judgment in the sum of $24,665.06 is to be entered for the plaintiff, with interest from the date of the finding, June 13, 1923.
So ordered.
