delivered the obinion oe the court.
On October 25, 1892, appellees entered into a written contract with appellant to furnish 150,000 quarter-barrel staves, at thirty-two dollars per thousand, and 150,-000 half-barrel staves, at forty-six dollars per thousand, “to be delivered between the date of the contract and the first day of January, 1894, in as nearly equal monthly shipments as possible.” 125,000 staves were delivered under this contract, and paid for by appellant. On July 25, 1893, appellant- addressed this letter to appellees: “G-entlemen: Your several favors twenty-fifth instant to hand, and noted. We wish to say that we do not want you to ship any staves at all for at least sixty days, as we will be unable-to receive them, so you had better save the hauling in and the freight, any way. Of course, we don’t hold yon to finish contract on 1 ime. As we have never pushed you when you were back on contract, we do not want you to push us now when we can not make use of the staves, and it is impossible to make collections. We do not want to give out any paper, and thereby get into a pinch, as we want to be on the safe side.” This was the last of a number of letters of the same tenor, beginning in the early part of July, and when the sixty days had expired appellant notified appellee that they would not take any more staves at any price. Thereupon this suit was instituted by appellees to recover damages for breach of contract, alleging thát, by the refusal of appellant to comply with the contract, they were damaged in the sum of $11.40 on each thousand staves which it refused to receive.
Appellant in its answer and counterclaim denies that appellees were damaged in the sum of $11.40 on the *704thousand staves, and alleges that after the execution of the contract, relying upon plaintiff’s promise to deliver the staves in as nearly equal monthly shipments as possible, from the twenty-fifth day of October, 1892, to the first day of January, 1894, they adjusted their business to consume monthly 10,575 quarter and 10,575 half-barrel staves, but that appellees failed to deliver, in the months of November, December, January, February, and March, 50,575 half and 31,920 quarter-barrel staves, and that by reason of such failure it was unable to work its factory to its full capacity, or to meet the demands of its customers for barrels during this period, and in consequence suffered damages in the sum of $2,819; and in amended answer it alleged that, on account of appellees’ failure to deliver the staves in as nearly equal monthly shipments as possible, between the months of December and April they were compelled to buy 14 car loads of staves to make up the deficiency caused by appellees’ failure, which cost it $377.30 more than the contract price made with appellees; and asked judgment therefor on their counterclaim. Trial before a jury resulted in a verdict and judgment for appellees for $1,600, and we are asked to reverse that judgment on several grounds: First, because the damages are excessive, and appear to have been given under the influence of passion and prejudice; second, because the verdict is not sustained by sufficient evidence, and is contrary to law; and, third, because the court erred in allowing plaintiffs to prove the profits they might have made on the staves if they had been permitted to ship them.
It appears from the proof that under the contract appellees realized • a net profit of from eleven dollars to twelve dollars a thousand on the staves actually deliver*705ed, and that they would have realized this amount on all of them if the contract hac] been complied with. At all events, this was a question of fact for the jury, if they were properly instructed. By the first instruction the jury were told: “If you shall believe from the evidence that plaintiffs entered upon the contract between them and defendant, introduced in evidence, and that they were ready, able, and willing to fulfill the same, but that defendant, during the existence of the contract, and before its completion, notified plaintiffs not to continue its fulfillment, and that they would not receive or pay for any more staves contracted for, you will find for plaintiffs in damages, the difference between the market price and the contract price, at the place of delivery, of any staves they had manufactured and had on hand at the time of such notification or refusal of defendant, and the profits, if any, which would have accrued to them by the manufacture an'd delivery to . the defendant of the remaining staves, up to 300,000, necessary to complete the contract, such profits to be ascertained by deducting from the contract price, the cost and expense of manufacturing and delivering said staves at the place they were contracted to be delivered, and such further deduction as you find to be reasonable for the less time engaged by plaintiffs, and for their release from the care, trouble, risk, and responsibility attending a full execution of the contract,— the whole damage found in no event to exceed $1,998.00.”
There was nothing speculative about the profit which appellees would have realized under their contract; the testimony reduced it to almost a mathematical certainty. In Thompson v. Jackson, Owsley & Co., 14 B. Mon., 114, this court said: “On failure to comply with a contract to *706deliver eight hundred hogs, to be slaughtered between specified periods, if the hogs are not delivered, according to contract, and the plaintiff show his readiness to slaughter them according to his undertaking, the criterion of damages is the net profit of slaughtering the hogs over the expense and trouble of slaughtering at customary prices.” And in E. & P. R. R. Co. v. Pottinger & Bro., 10 Bush, 185, this court said: “Damages which are the natural and proximate consequences of the act complained of may undoubtedly be recovered. Profits which are the direct and immediate fruits of the contract violated are part and parcel of it, and must have, been contemplated by the parties when it was entered into, and profits growing out of the execution of the work to be done, as the building of a house, come within this rule.”
The general rule is that the measure of damages for breach of an executory contract includes loss of profits which grow out of the contract, and which would have been realized from its full performance, but not the loss of profits or other damages arising out of collateral undertakings entered into on the faith of the contract. It seems to us that the instruction given in this case lays down the true and correct measure for determining the amount appellee was entitled to recover, and the instructions fully and fairly submit the case on appellant’s counterclaim.
It is insisted for appellant that as, subsequently to the institution of this suit, Tate & Co. executed a deed of assignment, they can not maintain this action. The deed referred to purports to convey only certain specific articles, and does not include the claim sued on.
A number of other rulings are complained of, but do not appear to have affected the substantial rights of the appellant. It is evident, from the letters of appellant filed in *707tbe record, that they waived any ground of complaint which they might have had for failure of appellees to furnish the proper number of staves during the months of November, December, January, February, March and April, and their subsequent refusal to comply with their contract had no connection whatever with such failure. The judgment is affirmed.
