In sending specimens of plants for investigation it is desirable 
to include the entire plant; if it is too large, portions showing 
leaves, flowers, and fruit are sufficient. It is best to prepare the 
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. When ilried plants are sent they should be 
protected fV<jin breakage in the mail by being Inclosed in sheets of 
paper between pieces oi stilT pasteboard. If specimens arc to be sent 
fresh, moisten them slightly and pack them tightly in a box or in a 
bundle, wrapping tlunn in heavy paper. Write the tiamo of the 
sender on the ouLside. In the letter accompanying tlie spcciincus 
state where each plant was coUected, flue date, the name of the 
collector, and add any other 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.
