IMPLEMENTS FOR COLLECTING. 15 
without injury, all insects placed in it. Great care should be used 
in handling the cyanide. Do not breathe the fumes of it as they are 
deadly poison. 
A more convenient and more useful article for killing insects can 
be made in the following manner: Purchase at the drug store a 
small box with a sliding cover and dovetailed corners, six inches 
long, four inches wide and three inches deep. It may be difficult to 
get a box as shallow as this, but if the other dimensions are right, it 
may be cut down to the right height. This box should be taken to 
a glazier, and have him fit into it one piece of glass for a sliding 
cover and five pieces for bottom and sides. These latter pieces 
should be fastened on with shellac, and thin glass should be used to 
make the box as hght as possible. When the shellac is dry, put in 
the cyanide as with the tumbler. This box will hold a large number 
of insects with papers between them, and will be found very useful 
when one is doimg much collecting. Occasionally the cyanide 
becomes so dry in the collecting box or bottle that it fails to kill the 
insects quickly. The addition of a few drops of water will gener- 
ally restore it to full strength. 
A small leather satchel suspended by a strap from the shoulder is 
a first-class addition to the collector’s outfit. Into it may be put the 
captured insects in their envelopes or collecting papers, with needles 
and thread for mending the net or the clothing, insect forceps, etc. 
A small light box with straps attached may be used in place of the 
satchel. 
Collecting papers or envelopes are made thus: Take smooth,
