The superficial view I have yet had time to take of your treatise on the cotton plant, induces a belief that it is rich and correct in its matter, and contains a great fund of learning on that plant. When retired to rural occupations, as I shall be ere long, I shall profit of its contents practically, in the culture of that plant merely for household manufacture. In that situation, too, I shall devote myself to occupations much more congenial with my inclinations, than those to which I have been called by the character of the times into which my lot was cast. About to be relieved from this _corvée_ by age and the fulfilment of the _quadragena stipendia_, what remains to me of physical activity will chiefly be employed in the amusements of agriculture. Having little practical skill, I count more on the pleasures than the profits of that occupation. They will give me, too, the leisure which my present situation nearly denies, of rendering such services as may be within my means, to the Institute, the Agricultural Society of the Seine, to yourself, and such other worthy individuals as may find any convenience in a correspondence here. I shall then be able particularly to fulfil the wishes expressed, of my sending to the Society of Agriculture a plough with my mould-board. Perhaps I may be able to add some other implements, peculiar to us, to the collection which I perceive that the Society is making. I salute you, Sir, with assurances of great esteem and respect. TO THE SECRETARY OF THE NAVY. WASHINGTON, July 16, 1808. DEAR SIR,--Complaints multiply upon us of evasions of the embargo laws, by fraud and force. These come from Newport, Portland, Machias, Nantucket, Martha's Vineyard, &c., &c. As I do consider the severe enforcement of the embargo to be of an importance, not to be measured by money, for our future government as well as present objects, I think it will be advisable that during this summer all the gun-boats, actually manned and in commission, should be distributed through as many ports and bays as may be necessary to assist the embargo. On this subject I will pray you to confer with Mr. Gallatin, who will call on you on his passage through Baltimore, and to communicate with him hereafter, _directly_, without the delay of consulting me, and generally to aid this object with such means of your department as are consistent with its situation. I think I shall be able to leave this place by Wednesday. I will mention for your information, that the post for Milton leaves this place on Tuesdays and Fridays, and arrives at it on Sundays and, I believe, Thursdays. I salute you with affection and respect. TO MR. SMITH, OF THE WAR OFFICE. WASHINGTON, July 16, 1808.
