and retain the gas. On top of each set of combs, place a cloth about ten 
inches square (doubled), and pour a tablespoonful of carbon bisulphide 
on the cloth and cover with two thicknesses of newspaper to insure a tight 
joint. Then place another body on top and treat the same way, and con-

OTHER ENEMIES.—Insectivorous birds, such as kingbirds, bee mar- 
tins and a few others sometimes prey on bees. They do no great damage 
when they capture workers; but when they capture queens in queen- 
rearing yards the case is more serious, and the owner would probably be 
justified in waging war on such birds. 
Mosquito hawks or “devil’s darning-needles” are often very destruct- 
ive to bees in some of the southern states, but do no damage in the North. 
In-the South lizards also frequently prey on bees. Spiders are sometimes 
mistakenly considered enemies of bees; but, from the way they make war 
on the moth miller, we think the spider should be called the beekeepers’ 
friend: 
Wasps, hornets and yellow jackets sometimes capture bees, but there 
are very few places where they are really troublesome.
