 PACKING AND SHIPPING SPECIMENS. 



Pressed specimens should be shipped in the original sheets in 

 which they were collected, and these should be securely tied in 

 bundles of about 50 between pieces of heavy cardboard or binder's 

 board of the same size. Care should be taken to alternate thin and 

 thick specimens in such a way that a flat package is obtained. Such 

 bundles can be sent through the mails singly without damage, or if 

 too numerous the}' can be packed in boxes. In the latter case care 

 should be taken to pack tightly and fill all vacant spaces with 

 crumpled paper in order to hold the bundles firmly in place.
