is now a question of control. Now abong the first things 

 we used against the San Jose scale was one of these mechan- 

 ically-made kerosene and water mixtures. They were very 

 unsatisfactory, and we soon discovered that the sprays they 

 threw out were sometimes water and sometimes oil. Over in 

 our state they have practically been discarded. Then came 

 whale oil soap, and for a time that was the principal thing; 

 it was found that two pounds to a gallon must be used, and 

 that was applied late in winter or early spring, but whale 

 oil soap at two pounds to the gallon is expensive. Four 

 cents is a pretty cheap price for whale oil soap, and eight 

 cents a gallon makes a very expensive spray. Then we came 

 to the oil sprays and crude petroleums. They raged for some 

 time, and are still used largely in the neighboring" state of 

 New Jersey. I saw a large apple tree sprayed with crude 

 petroleum, and it killed all the buds ; the trees are still alive, 

 but it killed the fruit for that year. It could be done by careful 

 men with very fine nozzles, but the question is, will not the 

 accumulative effect be very destructive, and that is the gen- 

 eral impression in New York state. After the oil sprays, 

 then came the lime and sulphur wash, which was tried very 

 soon in the east after the scale came, but conditions were 

 unfavorable, I have been told, but fruit growers began to 

 take it up and have got good results, and at the present time 

 it is tJic spray for the San Jose scale, and I think very justly 

 so. Then the later sprays were K-L mixture or "limoid." I 

 have had a little experience with those, and that experience 

 was very disagreeable. I was not able to make a good 

 mixture, one that was satisfactory in the way of being able 

 to put it on the trees in good shape. I found it did not 

 spread, and I had to use two or three times as much as you 

 did with some of the other sprays such as lime and sulphur. 

 It was unsatisfactory as to results. Now the later things on 

 the market are the missible or soluble oils. As was mentioned 

 here this afternoon, there is no question but what oil sprays 

 will spread better than any other sprays over rough bark ; 

 it will drive into the cracks and crevices better. But the 

 question of crude oil used through mechanical pumps is 

 of verv doubtful success, and liable to great injury, so if
