The terms of my engagement here are these. This situation became vacant by the death of Mr. Edgerton in April last. I was recommended by some of my friends, and finally made an arrangement for one year; took charge of a class in botany and mineralogy on 20th May; closed July 30. Have been at liberty until now; have just commenced a chemical course, to continue nine weeks, which will conclude my duties for the year. The compensation is board, room, washing, fuel, and all other expenses of the kind, for the whole year, or as much of the year as I choose to remain here. All expenses of the laboratory are defrayed (which by the way are not likely to be heavy), and in addition I receive $300. The advantages of the situation are, leisure and the means of a comfortable support. The disadvantages, the school is not incorporated and though now flourishing may not continue so, the scholars are too young, the principal wishes to retain too much of the Eatonian plan to suit me, and they have not furnished the means for the chemical course which I had a right to expect. No arrangement has been made for another year, but I have reason to think I shall be requested to remain another year. I am confident my leisure time would be employed to greater advantage if I was situated so as to have access to good libraries and extensive collections. At present I can be satisfied with a moderate income, sufficient for a comfortable support, for the purchase of a few books, etc.; but that income must be sure; I cannot afford to run any risks about it. I would willingly collect plants the whole summer, take on my hands the whole labor of preparing and arranging them, but as the proceeds would be absolutely necessary for my support, so they should be certain. I am now advantageously situated for the collection of plants, etc., as, if I choose, I can travel every year with a class who will defray my expenses. If you still desire to make such arrangement, please to state more explicitly the duties you wish me to perform; how much time can be given to collecting plants; what compensation you can afford me, supposing nearly the whole summer is devoted to making collections, and three fourths of the whole to belong to you,--or propose any plan which would be satisfactory to you, and I will let you know, very shortly, whether I will accept it or not. I had rather leave it to yourself than to make any definite proposition at present. I am confident we can make an arrangement which will be mutually beneficial. I need not say that I wish to hear from you again on this subject as soon as possible, as I must soon make my arrangements for the ensuing season. How large is the class at the Medical College? I have just returned from a visit at Fairfield; they have a class of about 190. In haste, Yours very respectfully, A. GRAY. UTICA, January 23, 1833.
