36 The Bulletust. 



straining before spraying will pay for tlie trouble many times over. If 

 one uses considerable quantities of tbe mixture, it is well to have a large 

 funnel strainer made, fitted with two nettings, one of iron wire window- 

 screening and the other with much finer guaze, preferably of brass. 

 Having strained the poisoned mixture, it is ready to apply. 



SELF-BOILED LIME-SULPHUR WASH. 



The tests of the United States Department of Agriculture indicate that 

 this is the best material to use on peaches in all treatments when there is 

 fruit or foliage on the trees. Some growers use it on apples instead of 

 Bordeaux or commercial washes. The slaking lime does the boiling, no 

 fire being used in boiling the wash itself, though hot water is used for 

 slaking the lime. 



Stone lime (unslaked) 8 pounds. 



Sulphur 8 pounds. 



Water (to make) 50 gallons. 



Arsenate of lead paste 3 pounds. 



Place the lime in tub or barrel and pour over it enough water to cover 

 it (preferably hot). Put in the sulphur (lumps first crushed) and add 

 another bucket of hot water. As the mass boils from the slaking of the 

 lime stir it, add more hot water as needed to form a thick paste at first, 

 and then gradually a thin paste. A sack or blanket over the barrel helps 

 to keep in the heat. When the boiling is all over add water (cold is all 

 right) to make 50 gallons, stir thoroughly and strain it carefully.* 



Adding the Poison. — Dissolve the arsenate of lead paste in enough of 

 the solution to make it liquid, then stir it into the whole solution, and 

 you are ready to spray. If powdered arsenate is used, use half the 

 weight. 



WHAT POISON— ARSENATE OF LEAD OR PARIS GREEN? 



Throughout the State as a whole Paris Green is the poison most com- 

 monly used against insects. Its use is so common that everybody is more 

 or less familiar with it, and it can be bought in almost every village. As 

 a rule, it does reasonably well, and can be used as the poison in spraying, 

 at the rate of about Vo pound to a barrel of the spraying liquid. 



But in recent years Arsenate of Lead has come into great favor, and 

 all experience shows it to be so much better than Paris Green that we 

 unhesitatingly give it first choice. The relative merits of the two may 

 be expressed as follows : 



Paris Green is more commonly known, is easier to get, costs less for 

 the amount needed ; but it is more likely to "burn" the leaves and fruit,
