438 CORRESPONDENCE. [1858, 
April 26. 
My last book! 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.? 
February 23, 1858. 
I dare say you may learn something here as to 
teaching, ete., 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 Iam 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 ~~ 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. 
1 How Plants Grow. Sir Joseph Hooker in Nature, February 16, 
1888, says of How Plants Grow and How Plants Behave, ‘‘ that for 
charm of matter and style they have no equal in botanical literature.’’
