In sending specimens of plants for investigation it is desirable 
to include the entire pla.it; if it is too large, portions showing 
leaves, flowers, and fmit are sufficient. It is best to prepare the 
specimens by drying tliem mider pressure between folds of absorb- 
ent paper, otJienvi.se the parts may shrink and, break so as to be 
hardly rccoguizablp. When dried plants are sent they should be 
protected from breakage in the mail by being inclosed In shei'ts ot 
paper between piece# of stiff pasteboard. If spcciimms arc to bo sent 
fresh, moisten them slightly and packtiiem tightly in a bo.\ or m u 
bundle, wrapping them in heavy paper. Write- the name of the 
sender on the outside. In the letter accompanying the specimens 
state whore each plant was collected, tin; date, the name of the 
collector, and add any other notes in regard to the economic value 
of the plant. 
Packages weigliing less than four pounds may ho sent by mail 
at tlie rate of one cent per ounce.
