DEAR SIR,--Your letter of the 10th has been received, and I note what is said on the provision which ought to be made by us, for the militia in the field. An arrangement by the Secretary at War to meet certain other persons at New York, to concert a plan of defence for that city, has occasioned necessarily his temporary absence from this place, and there is no person sufficiently informed to take the necessary measures until his return, which will be on Tuesday or Wednesday next. I hope no great inconvenience may be experienced if it lies till then. It has been suggested to me that if the British vessels should be disposed to leave our waters, they might not be able to do it without some supplies, especially of water; and it is asked whether supplies to carry them away may be admitted? It has been answered that, on their giving assurance of immediate departure from our waters, they may have the supplies necessary to carry them to Halifax or the West Indies. I must pray you to instruct Gen. Matthews to permit it, if he be applied to. But it is best that nothing be said on this subject until an application is actually made by them. Their retirement would prevent the necessity of a resort to force, and give us time to get in our ships, our property, and our seamen, now under the grasp of our adversary; probably not less than 20,000 of the latter are now exposed on the ocean, whose loss would cripple us in the outset more than the loss of several battles. However pleasing the ardor of our countrymen, as a pledge of their support, if war is to ensue, as is very possible, we, to whom they trust for conducting their affairs to the best advantage, should take care that it be not precipitated, while every day is restoring to us our best means for carrying it on. I salute you with friendship and respect. TO MADAME DE STAEL DE HOLSTEIN. WASHINGTON, July 16, 1807. I have received, madam, the letter which you have done me the favor to write from Paris on the 24th of April, and M. le Ray de Chaumont informs me that the book you were so kind as to confide to him, not having reached Nantes when he sailed, will come by the first vessel from that port to this country. I shall read with great pleasure whatever comes from your pen, having known its powers when I was in a situation to judge, nearer at hand, the talents which directed it.
