In sending specimens of plants for investigation it is desirable 
to include the entire plant; if it is too large, portions showing 
leaves, flovk-ers, and fruit arc sufficient. It is best to prepare tlie 
specimens by drying them under pressure between folds of absorb- 
ent paper, otherwise the parts may shrink and break so as to be 
hardly recognizable. Wlien dried plants arc sent they should be 
protected fVom breakage in the mail by being inclosed in sheets of 
paper between pieces of stitfpastcboard. If specimciifl are to be sent 
fresh, moisten them slightly and puck them tightly in a box or in a 
bundle, wrapping them in heavy paper. Write the name of the 
sender on the out-sido. In the letter acoompanying the specimens 
state where each plant was coLlocted, the date, tlie name of the 
collector, and add any otlicr notes in regard to the economic value 
of the plant. 
Packages weighing less than four pounds maybe sent by mail 
at the rate of one cent per ounce.
