In sending specimens of plants for investigation it is 
desirable to have the leaves, flowers, and fruit ; and, in t he 
case of bulbous jjlants, the bulbs, also. Wtiea they aro 
sent from a distance it Is best t-> proj)are the specimens 
by drying them under pressure between folds of absorb- 
ent paper, olhorwiso the parts shrink, and break so as to 
be hardly rocognlscable. "Wfien the dried plants are sent 
they should be protected from breakage in the mail by 
being inclosed between jdeces of stiff pasteboard. Pack- 
ages weighing loss than four pounds (jan be sent by mail 
at the rale of one cent per ounce. Write the name of the 
sender on the outside. In the letter accompanying the 
specimens state where collected, the date, and any other 
particulars of the plant, whether reputed poisonous, pesti- 
ferous, medicinal, or useful.
