Small specimens are placed in pill-boxes or similar thin boxes 
specially designed, which are enclosed in packets, a safer and 
better way than fastening them directly to the sheet. A very 
convenient arrangement for special or odd sizes is a small open 
ox with cardboard bottom and sides of cypress or white pine 
or cork strips attached with glue, which box is enclosed in a 
packet. This device is excellent for microscopic slides, which also 
properly belong in the herbarium series with the specimens. 
he older mycologists mounted their specimens so that they 
might readily be seen as the sheets were turned, a method with 
obvious advantages, but, unfortunately, very destructive to the 
specimens. A rather expensive substitute for this method is the 
use of envelopes with transparent fronts and boxes with glass or 
celluloid tops, which might at least be employed for sample sets 
of species to be used for ready reference in the identification of 
new material. 
All specimens, however mounted, should be inspected at least 
once a year, and a small quantity of naphthalene flake added to 
the boxes or packets in which they are kept in order to prevent 
invasion by insects. Suggestions from other curators will be 
welcomed.

A COLLECTION OF JAPANESE CHERRY TREES. 
In April, 1910, Mrs. Florence Lydig Sturgis offered to present 
the Garden with a collection of Japanese Cherry Trees, and 
the Board of Managers, at a meeting held April 18, 1910, author- 
ized the Director-in-Chief to gratefully accept this gift. 
A site for this plantation was selected last summer in a valley 
in the arboretum, contiguous to the collection of other kinds of 
cherry trees, and the ground was prepared for the plantation 
during the autumn. The path system of the arboretum planned 
for this part of the grounds was partly built during the fall and 
winter and completed early this spring. We were fortunate to
