Heat from 4 to 6 gallons of water to boiling over fire in large iron or 

 brass kettle. Mix the sulphnr with enough hot water to make a thin 

 paste, and pour it into the kettle with the hot water. Now add the lime, 

 part at a time, and as it slakes dash in a little cold water as needed, to 

 keep it from boiling over or to keep it from becoming dry. Keep the fire 

 going and stir the mixture frequently. As the slaking ceases, keep it boil- 

 ing from the fire for half an hour longer, then dilute with water (cold is 

 all right) to make 50 gallons; strain through a fine wire screen or cloth 

 to remove all sediment, and spray. 



This wash, which contains 15 pounds sulphur to the barrel, is only for 

 use in winter ivhen the trees are dormant. It is an excellent remedy for 

 San Jose Scale, but all treatments with it should be finished befoi'e the 

 buds open in spring. The later the treatment is made the better, just so 

 the buds are not open. Made according to the above directions, this wash, 

 as we apply it to the trees, costs about II/2 to 3 cents per gallon, depend- 

 ing upon the quantities of the ingredients purchased. It has the advan- 

 tage of being cheaper than the ready-made. It also makes a whiter coat- 

 ing on the twigs, so that missed portions can be more readily noticed 

 (and corrected), and for these reasons many prefer it, though it requires 

 the trouble of boiling, straining, etc., which in the minds of many offsets 



the cheaper cost. 



SOLUBLE OILS. 



The soluble oils share popularity with the lime-sulphur preparations 

 as remedies for the San Jose Scale. They are so prepared that they mix 

 readily with either hot or cold water, and are therefore very convenient 

 to use. They will penetrate into cracks and crevices even better than the 

 lime-sulphur mixtures, and they corrode and rust the spray pumps less, 

 but they do not have so good an effect in checking fungous diseases. 



The soluble oils are usually used in winter for San Jose Scale at the 

 rate of one gallon to ten gallons of water. 



The two firms which do most trade in this State in the soluble oil 

 preparation are : 



B. G. Pratt Company, 50 Church St., New York City, who make a 

 material called "Scalecide." 



Thomsen Chemical Company, Baltimore, Md. "Orchard Brand Solu- 

 ble Oil." 



If interested, correspond direct with them as to all details.
