In sending specimens of plants for investigation It is desirable 
to include the entire plant; if it is too largo, portions showing 
leaves, flowers, and fmit are sufficient. It is best to prepare the 
specimens by drying them under i)rcssurc between folds of absorb- 
ent paper, otherwise the parts may shrink and break so as to he 
hardly recognizable. When dried plants are sent they should be 
protected from breakage in the mall by being inclosed in sheets of 
paper between pieces of stiff pasteboard. If specimens are to he sen t 
fresh, Tnolsten lliem slightly and pack them tightly in a l)ox or in a 
bundle, wrapping tliem in heavy paper. Write the name of the 
sender on the outside. In the letter nceoinpanying the specimens 
state where each plant was collected, the dale, the name of the 
collector, and add any other notes in regard to the economic value 
of the plant. 
Packages weighiiig less than four pounds maybe sent by mail 
at the rate of one cent per ounce.
