vo correspond ; collect, dry, and prepare, as already directed, a number of 
specimens and attach labels to them, numbered 1, 2, 3, etc., and send 
them in a secure package (a light wooden box of the size of your driers 
is the best) to your correspondent, who will return you the generic and 
specific names of numbers 1, 2, 3, etc., which you can write on your own 
labels of the corresponding numbers. 
N. B.—Having named your plants, take your Flora and study the char- 
acters of the Order, Genus, and Species of each plant, and you will soon 
be independent of all assistance except such as you will be able to get 
from your books.
