THE BLACKBERRY 
Material 
Five or six blackberries per pupil. For this allow at least one quart box 
for twenty pupils. Pins; sharp knives; small pieces of white blotting paper. 
If possible, have pieces of bramble to show stem, thorns, leaves, and the 
old hull, or calyx, from which the berries have been picked or have fallen. 
This can be procured in the summer from wild blackberry vines and dried. 
The leaves may be dried on them also, or may be removed and pressed. 
By cutting stems in four or five inch lengths while they are fresh, they can 
be packed in a small box and transported without trouble. If the stems 
are not thoroughly dry before packing, they will mold, 
In packing sprays with the calyx it is advisable to wrap each separately 
in a bit of paper, otherwise they will be badly damaged in the unpacking.
