240 SECOND THOUSAND QUESTIONS IN AGRICULTURE 



home-made arsenate of lead as follows: Take the arsenate of soda 

 and dissolve this in a gallon of water (preferably hot) and in another 

 gallon of water dissolve the acetate of lead. When completely dis- 

 solved pour the two simultaneously into the mixing tub containing 

 the rest of the fifty gallons of water; stir well and the spray is ready. 

 The use of wooden vessels is advised in handling these solutions. 



Where a stronger poison is desired the arsenate of lead can be 

 increased to three or four pounds. A more uniform distribution of 

 the arsenate of lead is secured throughout the spray when it is added 

 to the milk of lime instead of placing it in the spray tank.

WAYS TO FIGHT DESTRUCTIVE ANIMALS. 

 Protecting Foliage. 



What will keep deer from eating the leaves and tender twigs of 

 young fruit trees? Last year I set out 1,000 young apple and pear trees and 

 the deer ate the foliage off three times during the season. This last spring 

 I set out 1,500 more and the deer went at them about two weeks ago and 

 last week they very nearly cleaned them all up. Do you knozv of anything 

 that we can spray the foliage to keep than away? 



A spray which will keep chickens and rabbits from eating leaves 

 will probably make them too bitter for deer. W. C. MacFarlane of 

 Hanford advises as follows : "I asked for a remedy to prevent poultry 

 eating the leaves and bark off the peach trees, and was advised to use a 

 quassia chip solution. As I had handled quassia solution on a com- 

 mercial scale, I felt sure that would answer the purpose, and it did. The 

 fowls would seldom take more than the second bite. I used a spray 

 pump and sprayed it on the lower part of tree and trunk. I made the 

 solution as follows : Quassia chips, two pounds to one gallon of lukewarm 

 water ; let this soak forty-eight hours ; strain off the liquid and add
