438 CORRESPONDENCE. [1858, 



April 26. 



My last book 1 in elementary botany is now just 

 off my hands, and will be out in a fortnight. I hope 

 it will be of use. Forgive me for writing horn-books, 

 and I am now done with that sort of work. There 

 were several convincing reasons for doing it. 



TO DANIEL CADY EATON. 2 



February 23, 1858. 



I dare say you may learn something here as to 

 teaching, etc., if you can pick it up yourself, which, 

 after all, is the only way anything worth knowing is 

 obtained. But from now to the end of April I am 

 just overwhelmed with work, and shall have no time 

 to give any special instruction. 



At the opening of the term I begin my drilling of 

 Sophomores in the " Botanical Text-Book." My lec- 

 tures to a selection of Juniors, on Systematic Botany, 

 I do not ordinarily commence till April 1, but this 

 year I am able to begin early in March, though not 

 much work is done till May. You might attend 

 Agassiz's lectures, but he will not be back from Flor- 

 ida as soon as the opening of the term. 



Let me know how much instruction you have to 

 give this year, and of what sort, and I can see whether 

 I can help you much. I dare say you will teach very 

 well. 



There are certain little matters you might pick up 

 about class illustration and manipulation without it 

 costing you much time. We were just thinking of 

 sending you Wright's Hongkong ferns.

 1888, says of How Plants Grow and How Plants Behave, "that for 

 charm of matter and style they have no equal in botanical literature "
