In sending specimens ofplunts for investigation it is desirable 
to include the entire plant; if it is too large, portions allowing 
leaves, flowers, and fruit are sufficient. It is best to prepare the 
specimens by diying tlicm under pressure betw’cen folds of absorb- 
ent paper, otherwise the parts may shrink and break so as to be 
hardly recognizable. When dried plants arn sent they should be 
protected fi-om breakage in the mail by being Incloscdiu sheets of 
paper between pieces of stilt' iiastebnaiHl. If specimens arc to be sent 
fresh, moisten them slightly and pack tlieni tightly in a box or in a 
bundle, wrapping them in heavy paper, i’ackages weighing less 
than four pounds can be sent by mail at the rale of one cent per 
two ounces. Write the name of the sender on the nutside. In the 
letter accompanying the specimens state whore each plants was 
collected, the date, the name of tlio collector, and add any other 
notes in regard to the economic value of the plant.
