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 uiiiler pressure between folds of absorb- 
ent paper, otherwifie the parts may shrink and break so as to be 
hardly recogniaable. When dried plants are sent they should be 
protected from breakage in the mail by being inclosed in sheets of 
paper between pieces of stiff pasteboard. If speeimoiis are to be sent 
fresh, moisten them slightly and pack them tightly in a box or in a 
bundle, wrapjiing them in heavy paper. Write the name of the 
sender on the yntside. In the tetter aceornpanyltig the specimens 
state where each plant was collected, the liate, the name of tiic 
collector, and add any other notes in regard to tlie economic value 
of the plant. 
Packages weighing less than four pounds maybe sent l)y mail 
at tlie rat(( uf one cent per ounce.
