INSECTS AND DISEASES AFFECTING PLANTS. 279 



them. When on small areas, outside or in the greenhouse, 

 we find about the best plans are to lay fresh bones, or pa- 

 per covered with molasses, around their haunts. These 

 they will come to in large numbers. They should be re- 

 moved daily, and burned or otherwise destroyed. Another 

 method that we have found more destructive to them 

 than any other, is to puff Pyrethrum or Persian Insect 

 Powder from a strong bellows among them. The small- 

 est particle of this powder at once chokes and kills them, 

 though it must strike them dry to be effective; for we 

 find that when the powder lies damp on the floor, they 

 will run over it, and even burrow in it with impunity. 

 Nothing I have ever tried will " poison" Ants. Either 

 their instinct causes them to avoid it, or else they are not 

 affected by it. 



Angle Worms probably do no harm to plants ex- 

 cept to disturb and " glue up " the soil, but this is to 

 some extent hurtful to plants grown in pots or on 

 benches in greenhouses. A simple remedy is to slack 

 one pound of lime in fifteen or twenty gallons of water; 

 let the lime settle to the bottom, using only the clear 

 water, which will be sufficiently impregnated with lime 

 to destroy the worms. The same remedy can also be ap- 

 plied in the open ground; but Angle Worms do but little 

 harm in the garden. In placing plants in pots out-doors 

 or on an earth bench in the greenhouse, first sprinkle 

 over with lime, which will prevent the worms entering 

 the pots through the drainage holes.
