DEAR SIR,--In my letter of the 15th I informed you that I had authorized Governor Tompkins to order out such aids of militia on Lake Ontario and the Canada line, as he should find necessary to enforce the embargo, not exceeding five hundred, he proposing to repair thither himself to select trusty persons. I am now to request that you will have measures taken for their pay, subsistence, and whatever else is requisite. I enclose you applications for military command in favor of John B. Livingston and John Murphy, a letter from Governor Hull, and one from Howell Hern, who seems to have just cause of complaint against Captain Armistead; and I salute you with affection and respect. TO THE SECRETARY OF THE TREASURY. MONTICELLO, August 26, 1808. DEAR SIR,--Yours of the 17th was received only yesterday. It ought to have come by the preceding post. I mention the delay of your letters, as you may perhaps know how it happens. _Smissaert's Case._ The exportation of these doits was refused before, and I see no reason for a change of opinion. They are understood to be private property. If they were public, we might on a principle of comity permit their exportation in their own or any other foreign vessel. But comity does not require us to send our ships and seamen into the mouths of captors. I am not sufficiently informed of the conduct of the Batavian government towards our vessels at present, to derive any motive from that to affect the present case. Kettridge's letter, with yours to him and Blake, and Burt's letter, are now returned. I am in hopes the successes of our armed vessels will check the evasions of the embargo. I have received no letter from Governor Tompkins since that of the 9th, my answer to which, of the 15th, contained assurances which would fully meet any case of militia ordered out by him under five hundred, as to our answering the expense. I will write immediately to General Dearborne to provide pay and subsistence, and will send it open to his chief clerk at Washington, with instructions to him to take order in it immediately, to prevent the delay from General Dearborne's absence. I will also write to General Wilkinson to forward the recruits of New York to the positions you have named. Your circular for the North Carolina navigation, and the papers concerning the Mandarin, are not yet received. Astor's publication in the Aurora has sufficiently quieted me on that head. * * * * * P. S. No letter yet from Mr. Pinckney. TO CAPTAIN M'GREGOR. MONTICELLO, August 26, 1808.
