Washington Dec. 4. 07.
I have this day written you a letter of introduction for mr Thos. T. Jones, in which I have said a great deal of good of him, every word of which is true. but there is one truth omitted there which duty to you as well as myself requires that I should supply in a private & confidential letter. he is in the unhappy habit of intemperance, and I suspect he goes with an intention to endeavor to reform himself and get into business. I have given him the letter open that he may see how many good qualities he possesses, all of them marred by this single foible. seeing himself placed in his new residence, on the high ground which nature & education qualify him to hold, his resolution to give fair play to so many excellent qualities may perhaps be strengthened. of his pecuniary circumstances I am totally uninformed. I have supposed they depend chiefly on his exertions in his profession. I tender you my salutations & assurances of great respect
