Jack is now set in to work regularly. He passes from two to four hours a day at the College, completing his courses of sciences, and four hours at the law. Besides this, he will write an hour or two to learn the style of business and acquire a habit of writing, and will read something in history and government. The course I propose for him will employ him a couple of years. I shall not fail to impress upon him a due sense of the advantage of qualifying himself to get a living independently of other resources. As yet I discover nothing but a disposition to apply closely. I set out to-morrow on a journey of a month to Lakes George, Champlain, etc., and having yet a thousand things to do, I can only add assurances of the sincere esteem with which I am, dear sir, your affectionate friend and servant, TH. JEFFERSON. FRANCIS EPPES, Esq., Eppington. In a letter of the same date to Mrs. Eppes, he writes: _To Mrs. Eppes._ I received your favor of April 6th by Jack, and my letter of this date to Mr. Eppes will inform you that he is well under way. If we can keep him out of love, he will be able to go straight forward and to make good progress. I receive with real pleasure your congratulations on my advancement to the venerable corps of grandfathers, and can assure you with truth that I expect from it more felicity than any other advancement ever gave me. I only wish for the hour when I may go and enjoy it entire. It was my intention to have troubled you with Maria when I left Virginia in November, satisfied it would be better _for her_ to be with you; but the solitude of her sister, and the desire of keeping them united in that affection for each other which is to be the best future food of their lives, induced me to leave her at Monticello. _To Martha Jefferson Randolph._ Lake Champlain, May 31st, 1791.
