The cyanide is a deadly poison, and the fact that it is a harmless-looking white substance, not unlike lump sugar or rock salt and many other things, renders it one of the most dangerous poisons to keep about the house.

If this is preferred, get an ounce of it in a flat vial; stick the handle of a small camel's- hair brush into the bottom of the cork, and, holding the insect in a fold of the net, apply a drop to each side (for insects breathe through a row of minute holes along the sides), and it dies instantly. On a collecting trip you will also need strips of newspaper, in which the insects may be neatly folded without breaking the wings or legs. Insects are mounted in a number of ways. The com- mon method is to pin them in a large tray provided with a sheet-cork bottom and glass top; but these trays or cases are expensive and cannot be recommended for ^ POISON L, roR iMsrcis.
