the whole if funds are in the hands of the treasurer; if not, the whole would be received quite certainly within the year. I have only to say further that the college has now one hundred students, is situated in a beautiful village nine miles from Utica, has the best college buildings of any in the State, has a good faculty, etc. I urged the promise I had made of the visit to Georgia, which this plan would entirely frustrate, but promised to give him a definite answer within a fortnight. I can scarcely think of postponing my southern tour for another season; but the question comes to this, whether, in the present state of my finances, I had better expend $100 in that visit or earn $200 in the same time. I could also, I think, continue my engagements here in July and August, by which a little more of the trash might be pocketed, and return to New York in time to make a September excursion to the dearly beloved pine barrens of New Jersey, and spend the early part of fall in botanical work, and the winter in your laboratory. The term closes here the 23d of April (a little earlier than I supposed); so if the original plan is pursued I shall be in New York by the 26th of that month. If not, I shall be disengaged for a month, a portion of which I should like to devote, with my friend Dr. Crawe, to the minerals of St. Lawrence County. So rests the case. I told Dr. H. that I should write immediately to you, and be governed in a good degree by your answer. I have such a dislike to the appearance of vacillation which results from changing one’s plans when fully formed, that were it not for certain ulterior advantages, and that I wish to comply with the wishes, as far as may be, of a person to whom I am much obliged, I should promptly decline Dr. Hadley’s offer. An idea just this moment strikes me which, in its crude shape, I will communicate. In eight or ten days I can get to the metals. Suppose I could then get excused, and finish my course here next summer in connection with mineralogy, which for these youngsters would do pretty well; reach New York early next month; set out immediately for Georgia, and remain there until the latter part of May; return via Charleston; examine Elliott’s herbarium, and return here by the first of June. I may be quite sure that April and May would be healthy, but could there be plants enough collected, especially Gramineæ, to make it an object? Please say what you think of it. If you think it will do, I see no insuperable objection to carrying it into effect.
