1. The defendant concedes that in case of drafts or other negotiable paper intrusted to a bank for collection, *164where from the necessity of the case some other agent must be employed the collecting bank is agent of the owner of the paper. See Fabens v. Mercantile Bank, 23 Pick. 330; Phipps v. Millbury Bank, 8 Met. 79, 82. Its first contention is that the plaintiffs had no legal title to the draft either as drawn or by any indorsement, and that because they could not sue on the draft they have no action against any party to whom it was transmitted for collection.
But in the present case the Second National Bank of Boston in whose favor the draft was drawn was content to receive the draft and to attempt its collection for the benefit of the plaintiffs and so became their agent in the matter. This distinguishes the case from Allen v. Ayres, 3 Pick. 298, and other cases cited for the defendant. There was the same privity between the plaintiffs and the defendant which is found wherever-a contract turns out to have been made by one of the contracting parties as ■an agent for an undisclosed principal.
2. While the draft was accompanied by a slip specially requesting that it should not be protested, the letter of instructions ■also said “ Return at once all items unpaid at maturity. They must not be held for the convenience of parties.” The non-protest slip was not inconsistent with and did not waive these instructions. While the evidence tended to show that it was •the.practice of some banks to retain no protest items even where ■accompanied by instructions like those quoted it also showed •that it was not the practice of all banks, and the presiding judge found that the evidence offered did not prove a custom. This made it competent for him to find that a failure to return the draft at once when it was not paid at maturity was negligence on the part of the defendant in dealing with the draft. The evidence abundantly justified a finding that the defendant both failed to return the draft as directed and held it for the convenience of the drawee in direct violation of instructions.
3. It cannot be said as matter of law that the plaintiffs’ damages are remote. The drawee had property open to attachment to an amount much larger than the amount of the draft. The holding of the draft for nearly a month after maturity until he failed and made an assignment had as a natural consequence the entailment of a loss, which there is good reason to believe would *165not have been incurred if the defendant had at once returned the draft as instructed to do when it was not paid at maturity. The keeping of it by the defendant had for its natural consequence the deprivation of the plaintiffs of all opportunity to collect it by an action against a debtor who had unincumbered property in his possession open to attachment and who did not intend to fail or make an assignment.
Exceptions overruled.
