INGRAHAM, Eirst JUDGE. - Tbe plaintiff's claim is for moneys received by tbe bank upon collateral notes, deposited as security for other notes discounted by tbe bank for tbe firm of C. S. Benedict & Co. Before tbe notes were paid tbis firm' bad failed, and made an assignment to tbe plaintiff. After tbe assignment, tbe bank, without notice, paid a note .of Benedict & Co., wbicb was made payable at tbe bank, and tbey claim to be allowed, as an off-set, tbe amount of sucb note.
Upon tbe trial of tbe case, tbe plaintiff was permitted to call as witnesses, as to tbe custom of tbe banks in New York in payifif; tbe checks of dealers, persoDS who were not employed in banks. Although not employed in banking business, the witnesses were dealers with tbe banks, and bad knowledge of tbe ordinary course of dealing with them. There is no necessity for showing a man to be an expert in banking, in'order to prove a usage. He should know what tbe usage is, and then be is competent to testify, whether be be a banker, or employed in a bank, or a dealer with banks. There is no reason why a dealer should not have as much knowledge on sucb a subject as a person employed in a bank.
Tbe main question in this cause is, whether tbe bank is entitled to credit for tbe amount of tbe note of Benedict & Co. paid by tbe bank.
As between Benedict & Co. and tbe bank, I think there could' be no doubt that tbe defendants should succeed in tbe defence set up by them.' Tbe payment of - tbe note was by direction of tbe firm, inasmuch as tbey made it payable at tbe bank. Such a direction as to tbe place of payment, where tbe firm's account was kept in tbe bank, was equivalent to a direction or request for tbe bank to pay tbe same. Even conceding that tbe collaterals were not pledged as security for sucb payments, and that the bank could not have retained the notes after those to wbicb tbey were *186collateral bad been paid, still wben tbe collaterals are paid, and tbe claim is for money bad and received, a set-off is always proper. While tbe money was remaining with tbe bank, and before any notice of the transfer of interest to tbe plaintiff was given to the bank, they, at tbe request of Benedict & Co., paid tbe note of that firm. Such payment was a good defence to any claim for money collected by them on tbe collaterals, either as a payment for tbe firm out of those funds by their request, or as a set-off of tbe amount of tbe note for moneys paid for them at their request.
Is there anything, then, in tbe fact of tbe assignment to tbe plaintiff to alter tbe rights of tbe defendants to this defence.
Had notice of tbe assignment been given to
