an agitator. Set the barrel on a cart, waggon or 

 hand-cart, select a nozzle which is easily cleaned, 

 and that will form a mist-like spray of the solution. 

 As a fine spray cannot be thrown any distance, it is 

 advisable to attach two nozzles to a bamboo pole 

 (see III. 2j) and the hose fastened to the other end 

 of the pole. 



For the treatment of scab, caterpillars, codling Bordeaux 

 moth, bud moth, canker worm, leaf blight, etc., use 

 poisoned Bordeaux mixture, by adding Paris green. 

 This combination will destroy all masticatory and 

 suctorial insects. The results are as good as if each 

 were applied separately. The following is the for- 

 mula: Copper sulphate, four pounds; lime, four 

 pounds; Paris green, four ounces; water, forty 

 gallons (one barrel). Dissolve the copper sulphate 

 by suspending it in a bag (made of coarse material) 

 in a wooden vessel containing about live gallons of 

 water. It will dissolve more quickly in hot water. 

 Slake the lime in another vessel, and strain through 

 coarse sacking or a fine sieve ; dilute the slaked lime 

 in half a barrel of water, then pour the copper 

 sulphate solution into the barrel, with the diluted 

 lime. Add water to make the forty gallons; then 

 add the Paris green, which has been previously made 

 into a paste with water. 



The first spraying should be done when the buds Time to Spray 

 are swelling. The second spraying when the blos- 

 soms have fallen. A third application may be 

 necessary if any scab should appear on the fruit or 

 disease on the leaves. • 



For blight, which frequently affects the leaves spraying 

 of the potato plant, and later the tubers themselves, Potatoes - 

 use the same Bordeaux mixture that is recommended 

 for fruit trees, and for the potato beetle one pound 

 of Paris green to a barrel of water, placed on a cart
