the practice now, both in England and the United States, does not require more to be done, in the presentment of a bill of exchange to an acceptor for payment, than that the demand should be made of a merchant acceptor at his counting-room or place of business; and if that be closed, so in fact that a demand cannot be made, or that the acceptor is not to be found at his place of business, and has left no one there to pay it, that further inquiry for him is not necessary, and will be considered as due diligence
