In sending specimens of plants for investigation it is desirable 
to include the entire plant; if it is too large, portions showing 
loaves, flowers, and fruit arc sufficient. It is best to prepare the 
specimens by drying them un<ler pressure lietweon folds of absorb- 
ent paper, otherwise the parts may shrink and break so as to be 
hardly recognizable. Wlnui dried plants are sent they should be 
protected fVom breakage in the mail by being inclosed In sheets of 
paper between pieces of stlfl' pasteboard. If specirnens are to be sent 
fresh, moisten them slightly and pack them tightly in a box or in a 
bundle, wrapping them in heavy paper. Write the name of the 
sender ou tlie outside. In the letter accompanying the spceimotis 
state where each plant was collected, thu date, the name of the 
collector, and add any otlier 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.
