Dear Samuel
Yours of the 6^th inst has come to hand, in which you are asking for Ten Dollars to pay for your Tuition for five months, I suppose commencing on the 1^st of this month, which you will find here enclosed, pay it over to the proper person & take a receit for the same.
I should have sent the money with you but I thought that as I had advanced twenty Dollars at the time that I entered you as a Scholar that that amount was certainly sufficient for seven & one half months tuition & to pay a part of your Board & the balance I intended to settle at the expiration of this Session,  you only went to school about 2 ½ months in the last session which would only have cost five Dollars leaving fifteen out of which I intended Ten Dollars to have gone towards paying for your Tuition for the five months to come and the balance towards paying your board.
I seen Mr. Gannaways bill handed to you by himself, but believing that he had made a mistake in making it out, I thought that I would let it stand until

I could see him & we could then correct the mistake.
You will please show this to Mr Gannaway & request of him to give me a full explanation of the whole matter, as there seems to be something quite mysterious to me in this business.
We are all well & Wythe got home safe.

Your father
J. T. Gleaves
