During the present paroxysm of the insanity of Europe, we have thought it wisest to break off all intercourse with her. We shall, in the course of this year, have all our seaports, of any note, put into a state of defence against naval attacks. Against great land armies we cannot attempt it but by equal armies. For these we must depend on a classified militia, which will give us the service of the class from twenty to twenty-six, in the nature of conscripts, composing a body of about 250,000, to be specially trained. This measure, attempted at a former session, was passed at the last, and might, I think, have been carried by a small majority. But considering that great innovations should not be forced on a slender majority, and seeing that the general opinion is sensibly rallying to it, it was thought better to let it lie over to the next session, when, I trust, it will be passed. Another measure has now twice failed, which I have warmly urged, the immediate settlement by donation of lands, of such a body of militia in the territories of Orleans and Mississippi, as will be adequate to the defence of New Orleans. We are raising some regulars in addition to our present force, for garrisoning our seaports, and forming a nucleus for the militia to gather to. There will be no question who is to be my successor. Of this be assured, whatever may be said by newspapers and private correspondences. Local considerations have been silenced by those dictated by the continued difficulties of the times. One word of friendly request: be more frequent and full in your communications with us. I salute you with great friendship and respect. TO GENERAL KOSCIUSKO. WASHINGTON, May 2, 1808.
