These restrictions within narrow limits of time and space give security even to our maritime cities during three quarter of the year, and to the country always. Although from these facts it appears unnecessary, yet to satisfy the fears of foreign nations and cautions on their part not to be complained of in a danger whose limits are yet unknown to them I have strictly enjoined on the officers at the head of the customs to certify with exact truth for every vessel sailing for a foreign port the state of health respecting this fever which prevails at the place from which she sails. Under every motive from character and duty to certify the truth, I have no doubt they have faithfully executed this injunction. Much real injury has, however, been sustained from a propensity to identify with this endemic and to call by the same name fevers of very different kinds, which have been known at all times and in all countries, and never have been placed among those deemed contagious. As we advance in our knowledge of this disease, as facts develop the source from which individuals receive it, the State authorities charged with the care of the public health, and Congress with that of the general commerce, will become able to regulate with effect their respective functions in these departments. The burthen of quarantines is felt at home as well as abroad; their efficacy merits examination. Although the health laws of the States should be found to need no present revisal by Congress, yet commerce claims that their attention be ever awake to them. Since our last meeting the aspect of our foreign relations has considerably changed. Our coasts have been infested and our harbors watched by private armed vessels, some of them without commissions, some with illegal commissions, others with those of legal form, but committing practical acts beyond the authority of their commissions. They have captured in the very entrance of our harbors, as well as on the high seas, not only the vessels of our friends coming to trade with us, but our own also. They have carried them off under pretense of legal adjudication, but not daring to approach a court of justice, they have plundered and sunk them by the way or in obscure places where no evidence could arise against them, maltreated the crews, and abandoned them in boats in the open sea or on desert shores without food or clothing. These enormities appearing to be unreached by any control of their sovereigns, I found it necessary to equip a force to cruise within our own seas, to arrest all vessels of these descriptions found hovering on our coasts within the limits of the Gulf Stream and to bring the offenders in for trial as pirates.
