must decide whether or not he will go to the extra trouble of mak¬ 
ing the. emulsion or whether he will go to the extra expense of 
purchasing a special and somewhat more costly pump that may 
not work very satisfactorily at all times.

17 . GASOLINE. 
This oil is also destructive to insect life. Its chief use is for 
the destruction of bed-bugs. It is applied pure by means of an oil¬ 
can or hand atomizer. To be effectual the bugs must be thoroughly 
treated with it. As it is inflamable, care must be taken not to 
ring ~re near until the apartments where it is used are well aired. 
18 . TURPENTINE. 
Turpentine is used for the same purposes as gasoline and the 
same precaution applies. 
19 . EYE AND WASHING SODA. 
^hese substances are in considerable popular favor for the 
destruction of insects, but the writer’s experience with them has 
not been encouraging. In the proportion of a pound to three gal- 
ons of water they may be used upon the trunks of trees and will 
kill soft-bodied insects that might be wet by them. To be used 
upon foliage they should be diluted to a pound to forty gallons of 
water, and in this strength they will hardly destroy the tenderest of 
insects. . Kerosene emulsion or whale-oil soap are much more ef¬ 
fectual insecticides. 
20 . DIME. 
Kime, either wet or dry, may be used freely upon foliage with¬ 
out fear of injury. It is of very little value as an insecticide. When 
freshly slaked and freely dusted upon the slugs that infest pear, 
cherry and plum trees, it causes them to drop off and most 
of these perish. Experiments at this Station have not been wholly 
successful in killing slugs this way. As a coating upon the bodies 
of fruit trees it undoubtedly does much to prevent sun-scald late in 
winter and early in spring. The addition of a liberal amount of 
skim-milk or salt, or both, to the preparation will greatly increase 
its adhesive qualities. The following formula is printed in the 
1899 report of the Canada Experimental Farm: 
Skim-milk. 6 gallons. 
W & t er .30 gallons. 
.60 pounds. 
katt. 10 pounds. 
21. DIME, SALT AND SULFUR WASH. 
This wash, when properly made, is one of the most effectual
