Braley, J.

The declaration consisted of twelve counts. But only the first and fifth became material at the first trial when the plaintiff obtained a verdict for services alleged to have been rendered by him in the procurement for the defendant of contracts for the manufacture of munitions. The defendant’s exceptions to the verdict on the first count, which rested on a contract between the parties dated October 5, 1916, were overruled, but its exceptions to the verdict on the fifth count were sustained, Brand v. Sterling Motor Car Co. 243 Mass. 303, and the case is before us on exceptions of the defendant taken at the second trial confined to this count, on which the plaintiff again obtained a verdict.

The rights of the parties under the fifth count rest on the contract of November 15, 1917, which reads:

“ It is hereby agreed between W. T. Marsh, representing the Sterling Motor Car Co. of Brockton, Mass., and yourself that in consideration of and for services rendered and to be rendered in the assisting of securing a contract from the United States Government for One Pound Shells complete (sub-contracts for some of the parts to be allowed) also for the assisting in the financing of the order, that the following commission is to be paid to you by the Sterling Motor Car Company, based on the size of the order as per:

Order for 4,000,000 shells, commission to be .008 per shell. ” ” 3,000,000 ” ” ” .007 ” ”

” ” 2,000,000 ” ” ” .006 ” ”

” ” 1,000,000 ” ” ” .005 ” ”

“ It is further agreed that you are to raise cash or establish a credit based on the size of the order, as follows:

Order for 4,000,000 shells, maximum credit to be $400,000. ” ” 3,000,000 ” ” ” ” 300,000.

” ” 2,000,000 ” ” ” ” 200,000.

n ” 1,000,000 ” ” ” ” 100,000.

“ It is further agreed that the above commission is to be paid by the Sterling Motor Car Company to James H. Brand as and when the contract is signed and the cash delivered or credit established.

*322“ It is further agreed that the Sterling Motor Car Co. are to allow you Fifty Dollars (50.) per week for living expenses, should it become necessary for you to live in Boston and it is also agreed that you are to become Vice-President of the Sterling Motor Car Co. and are to devote such time as may be necessary to the interest of this company while the contract is in force.

“ It is understood that the credit to be raised by you is the chief object to this agreement.”

The construction of this contract was a matter of law for the court, and not a question of fact. It was admitted that the plaintiff, who was elected a vice-president of the company, assisted in procuring a contract which the defendant made with the United States for the manufacture of two million one pound shells, and, the contract having provided “ that you are to raise cash or establish a credit based on the size of the order,” the plaintiff contends, that he performed this part of the agreement by making arrangements for a loan with Spitzer, Rorick and Company, a firm of bankers, which failed of consummation because of the defendant’s fault. But the trial court, upon the evidence admitted on this issue which in substance was the same as at the first trial, followed the previous decision, that the plaintiff could not recover and declined to submit this question to the jury. The ruling was right. The plaintiff testified that Rorick acting for the firm agreed, if the defendant “ could furnish ... a satisfactory audited statement and he was satisfied with the management of the company,” the bankers would lend the defendant $200,000, the amount required to enable it to undertake the performance of the contract for munitions. It was admitted that the company did-not promise to furnish any statement, and the evidence of the plaintiff did not warrant a finding, that on the negotiations as disclosed he had earned a commission. Brand v. Sterling Motor Car Co. 243 Mass. 303, 317.

The plaintiff, to avoid this result as well as the effect of the former decision, offered evidence of a “ custom in the banking business for the lender to require and for the borrower to furnish audited statements where applications *323are made for loans from outside banldng houses or banks.” The evidence was excluded rightly. A custom could not be read into the contract which imposed on the defendant an obligation which it did not expressly or impliedly assume. Rosenbush v. Learned, 242 Mass. 297, 301.

The remaining issue was, whether the $200,000 advanced by the government to the company constituted either cash or a credit obtained by the plaintiff in performance of his contract. The contract is clear. Before the plaintiff could recover the stipulated commission on the order, he engaged to procure in cash or establish a credit for the company based on the size of the order, and, the order having been given for two million shells, the amount to be provided was $200,000. By U. S. St. 1917, c. 79, § 5, 40 U. S. Sts. at Large, 383, a War Credit Board was established which could make payments in advance to contractors making munitions for the government. The defendant, upon compliance with certain conditions required by the contract with the government, finally obtained an advance payment from the board of $200,000, and entered upon the performance of the contract. The plaintiff claims that he is entitled to a commission for obtaining the payment, a question not raised at the first trial. Brand v. Sterling Motor Car Co. 243 Mass. 303, 315.

The contract of the parties expressly provides, “ It is further agreed that you are to raise cash or establish a credit on the size of the order, as follows: ... for 2,000,000 shells, maximum credit to be $200,000,” and “ It is understood that the credit to be raised by you is the chief object of this agreement.” While the act of Congress was the law of the land, the parties had no actual knowledge of it when they made their contract. The plaintiff undertook to obtain the money from banks or bankers, either by a direct loan to the defendant of the entire amount, or by a system of credit on which the defendant could draw when necessary. While the defendant itself might have obtained the money, or the required financial assistance without the plaintiff’s services as a broker, yet if he performed his contract he could not be deprived of his commission. It is true the jury could find that, *324when all his various attempts to obtain money from outside sources had failed, he directed the defendant’s attention to the War Credits Board as a possible means of financing the defendant’s requirements, and exerted himself to secure an advance payment. The record however shows, that the board dealt with the contractors alone, and declined to negotiate with brokers. The sixth article of the contract with the government is explicit. “ The contractor shall use the money advanced under this agreement solely in the direct performance of the Principal Agreement,” which was the contract for the shells. It is manifest' from the plaintiff’s own evidence, that he knew of thesé conditions, and in his interviews with the board under the application made by the company for a loan he acted as vice-president. We quote from his testimony: “ I went to see them purely as a representative and officer of the Sterling Motor Car Company.” “ And you didn’t go there on a commission understanding? ” “ Not on a commission basis at all. It was simply as an officer worldng for the Sterling Motor Car Company.” The plaintiff moreover “ understood that the government required that every dollar of the money advanced by it to a contractor on an advance payment like this had to be applied to the purposes of the contract.”

The salient facts were insufficient to warrant a finding that the plaintiff either raised $200,000 or established a credit for this amount on which the defendant could draw. And, not having performed his contract, he had failed to earn a commission, and his employment as originally contemplated by the parties was ended. Fitzpatrick v. Gilson, 176 Mass. 477, 478. French v. McKay, 181 Mass. 485, 486. Smith v. Kimball, 193 Mass. 582. Bowes v. Henry, 228 Mass. 341.
