chased, or may be made up according to the following 

 formula: 



Pulverized resin 5 pounds 



Concentrated lye i pound 



Fish oil i pint 



Water 5 gallons 



Boil resin and oil in one gallon of water until the 

 resin is thoroughly softened, then dissolve and add the 

 lye slowly, stirring continuously until thoroughly mixed. 

 Then add four gallons of water and boil for about two 

 hours or until you get a clear amber-colored liquid which 

 dissolves readily in cold water. This liquid resin soap 

 may be added at the rate of one gallon to every 100 

 gallons of any arsenical spraying mixture other than 

 arsenate of lead, or at the rate of one gallon for every 

 fifty gallons of any spray used on cabbage or similar 

 waxy leaves. The adhesive should be placed in the 

 entire amount of water to be used and, when thor- 

 oughly dissolved, the Paris green or other poison should 

 be added. 



Powdered white hellebore was at one time almost 

 the main reliance against saw-fly larvae such as the 

 currant worm, and is even yet the favorite for this 

 purpose with many gardeners. It may be applied as a 

 dry powder, pure or mixed with two or three times its 

 own weight of cheap flour; or it may be used in the 

 form of a decoction, using one ounce, steeped in two 

 quarts of hot water. This is also effective against 

 certain small caterpillars and naked slugs, but is not so 

 reliable and is more expensive than some of the other 

 materials already recommended. 



Sometimes we can make use of certain abnormal 

 tastes among insects to secure their destruction. Thus 

 cut- worms prefer wheat bran to their normal food,
