TO GOVERNOR CABELL. MONTICELLO, August 19, 1807. DEAR SIR,--Your letters of August 11th, 12th, 13th, had been before acknowledged, and in mine of this morning I acknowledged yours of the 16th, and returned the papers enclosed in it. Since writing that, I have received another letter of yours of August 11th, which, by an error of the Post Office, had been sent to a wrong office. I now enclose the papers received in that. They call but for one observation, which is, that the mode of communication by flag, as before directed, must be adhered to. Although credit and indulgence is due to the liberality of Governor T. Hardy, yet armed vessels remaining within our jurisdiction in defiance of the authority of the laws, must be viewed either as rebels, or public enemies. The latter character, it is most expedient to ascribe to them; the laws of intercourse with persons of that description are fixed and known. If we relinquish them we shall have a new code to settle with those individual offenders, with whom self respect forbids any intercourse but merely for purposes of humanity. A letter which I wrote to the Secretary of State on the 17th, expressed my opinion that we should not higgle with the Columbine as to the quantity of supplies, but let her have what she wants. These small distresses contribute nothing to the bringing an enemy to reason. It should not be till an abuse of this liberality has taken place, that we should be rigorous in the quantum of supplies. I salute you with great esteem and respect. TO THE SECRETARY OF THE NAVY. MONTICELLO, August 20, 1807. DEAR SIR,--Mr. Appleton, the writer of the enclosed letter, was well known to me at Paris, but not as a man of business. He was young, handsome, and devoted to pleasant pursuits. He is now probably forty-five, and has since been in business, but with what qualifications or success I know not. He was our consul at Calais, his brother is our consul at Leghorn, and his father is (if living) a respectable merchant at Boston. All this leaves still room for inquiry whether he is fit for your agent. While on the subject, if you should be on the look-out, it may be worth your while to inquire after a Colonel Dowse, (of the same town with Fisher Ames.) He is a scientific navigator, has made voyages to the East Indies, is a sensible and most upright man, a little too much wrapt up in religious reveries. He has been most firm in his republicanism through all the storms and trials which those sentiments have been exposed to in that State. I write all this from my own knowledge of him; but I do not know he would accept the place and quit the retirement in which he has now been several years.
