The peculiar custom in England, of impressing seamen on every appearance of war, will occasionally expose our seamen to peculiar oppressions and vexations. These will require your most active exertions and protection, which we know cannot be effectual without incurring considerable expense; and as no law has as yet provided for this, we think it fairer to take the risk of it on the executive than to leave it on your shoulders. You will, therefore, with all due economy, and on the best vouchers the nature of the case will admit, meet those expenses, transmitting an account of them to the Secretary of State, to be communicated to the legislature. It will be expedient that you take proper opportunities in the mean time, of conferring with the minister on this subject, in order to form some arrangement for the protection of our seamen on those occasions. We entirely reject the mode which was the subject of a conversation between Mr. Morris and him, which was, that our seamen should always carry about them certificates of their citizenship. This is a condition never yet submitted to by any nation, one with which seamen would never have the precaution to comply; the casualties of their calling would expose them to the constant destruction or loss of this paper evidence, and thus, the British government would be armed with legal authority to impress the whole of our seamen. The simplest rule will be, that the vessel being American, shall be evidence that the seamen on board her are such. If they apprehend that our vessels might thus become asylums for the fugitives of their own nation from impress-gangs, the number of men to be protected by a vessel may be limited by her tonnage, and one or two officers only be permitted to enter the vessel in order to examine the numbers on board; but no press-gang should be allowed ever to go on board an American vessel, till after it shall be found that there are more than their stipulated number on board, nor till after the master shall have refused to deliver the supernumeraries (to be named by himself) to the press-officer who has come on board for that purpose; and, even then, the American Consul should be called in. In order to urge a settlement of this point, before a new occasion may arise, it may not be amiss to draw their attention to the peculiar irritation excited on the last occasion, and the difficulty of avoiding our making immediate reprisals on their seamen here. You will be so good as to communicate to me what shall pass on this subject, and it may be made an article of convention, to be entered into either there or here.
