In sending specimens of plants for investigation it is desirable 
to include tlie 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 ami break so as to be 
hardly recognizable. Wlien dried plants are tsent they should bo 
j)roteeted fVom breakage in the mail l)y being inclosed in sheets of 
paper between pieces of still paslel)oard. If Bpociinciis are to be sent 
fresh, moisten them slightly and pack them tightly in a l)ox or In a 
bundle, wrapping them in heavy pupc-r. Write tliC name of the 
sender on tlie outside. In the letter ncconvpunying the specimens 
state where each plant was collecti.-d, the date, the name of tlie 
collector, and add any other notes in regard to the economic value 
of the plant.
