WASHINGTON, November 15, 1807. DEAR SIR,--Yours of the 6th has been duly received. On the subject of your location for the winter, it is impossible in my view of it, to doubt on the preference which should be given to this place. Under any circumstances it could not but be satisfactory to you to acquire an intimate knowledge of our political machine, not merely of its organization, but the individuals and characters composing it, their general mode of thinking, and of acting openly and secretly. Of all this you can learn no more at Philadelphia than of a diet of the empire. None but an eye-witness can really understand it, and it is quite as important to be known to them, and to obtain a certain degree of their confidence in your own right. In a government like ours, the standing of a man well with this portion of the public must weigh against a considerable difference of other qualifications. Your quarters here may not perhaps be quite as comfortable as at Philadelphia. There is a good house half-way between this and the Treasury, where General Dearborne, Mr. and Mrs. Cutts, board together. I do not know if there is a vacancy in it, but there are houses all along the avenue, convenient to the Capitol, and to this house also, to come and take your soup with us every day, when not otherwise engaged. Our affairs with Spain laid dormant during the absence of Bonaparte from Paris, because we know Spain would do nothing towards settling them, but by compulsion. Immediately on his return, our terms were stated to him, and his interposition obtained. If it was with good faith, its effect will be instantaneous; if not with good faith, we shall discover it by affected delays, and must decide accordingly. I think a few weeks will clear up this matter. With England, all is uncertain. The late stuff by Captain Doane, is merely a counterbalance for the stuff we had a week before of a contrary aspect. Those dialogues they put into the mouths of the ministers were not likely to be communicated to the newswriters, and they are founded on a falsehood within my knowledge, not that I have confidence with an amicable arrangement with England; but I have not the less on account of this information. One circumstance only in it, I view as very possible, that she may by proclamation forbid all commerce with her enemies, which is equivalent to forbidding it with any nation but herself. As her commerce could not be accepted on such terms, this will be as much of a war as she could wage if she were to declare war, for she can wage only a maritime war with us. In such a case we could not let the war be all on one side but must certainly endeavor at as much indemnification as we could take. If we have war with her, we shall need no loan the first year, a domestic loan only the second year, but after that, foreign loans. The moment the war is decided, we shall think it necessary to take
