For the collecting and killing bottle (fig. 10) put into the bottom of a wide-mouthed bottle (a 4-oz or 6 oz quinine bottle) a tablespoonful of cyanide of potassium which has been broken into small pieces (as large as peas) and cover this with a layer, half an inch thick, of plaster of Paris mixed with water to form a thick paste. After the plaster has set (letting the bot- tle stand uncorked), put into the bottle a small crumpled bit of tissue paper (to prevent the shaking about of the insects and to absorb moisture) and the killing bottle is ready for use. It should be kept tightly corked. Insects caught with the net or with the hands have simply to be dropped into the killing bottle and the deadly Hig. 10. Kiiuug bottle; cyanide of potassium hydrocyanic gas which fills the at bottom, covered with plaster of Paris, bottle wiU kill them almost im- mediately. The insects may be left in the bottle until the school- room is reached, when they should betaken out and pinned up as described later. The cyanide of potassium used in the killing bottle is a deadly poison and the utmost care should be shown in its use. Perhaps it will be advisable to have a druggist make the bottles according to the above directions. Each bottle should be marked "Poison," and the pupils warned not to inhale the gas when the cork is removed. With collecting net and killing bottle, and a few small boxes for live specimens, nests, etc., the insect collector is outfitted. In collecting, visit flowers, turn over stones aud old logs, go into.
