10 PARIS GREEN.— WET. 



Paris green, i pound. 

 Quicklime, i to 2 pounds. 

 Water, 200 gallons. 



Slake the lime in part of the water, sprinkling in the Paris green 

 graduall}^ then add the rest of the water. For the peach and other 

 tender leaved plants use 300 gallons of water. Keep well stirred 

 while spraying. 



11 ARSENITE OF LIME. 



White arsenic, 2 pounds. 

 Sal-soda, 8 pounds. 

 Water, 2 gallons. 



Boil till the arsenic all dissolves, — about 45 minutes. Make up 

 the water lost by boiling and place in an earthern dish. For use 

 take one pint of this stock, 2 pounds freshly slaked lime and 45 

 gallons water, and spray. 



12 ARSENATE OF LEAD. 



Arsenate of soda (50^6 strength), 4 ounces. 

 Acetate of lead, 1 1 ounces. 

 Water, 100 gallons. 



Put the arsenate of soda in 2 quarts of water in a wooden pail, 

 and the acetate of lead in four quarts of water in another wooden 

 pail. When both are dissolved, mix with the rest of the water. 

 Warm water in the pails will hasten the process. For the elm-leaf 

 beetle use 10 instead of 100 gallons of water. 



A number of ready-made arsenates of lead are now on the 

 market, and except when very large amounts are needed it will prob- 

 ably prove cheaper to buy the prepared material than to make it. 

 With this ready-made material take 3 pounds to 50 gallons of water 

 for codling moth, and 5 pounds to 50 gallons for the elm-leaf beetle 

 and on potatoes.
