on this. In the old orchard where the ground was spaded deep, 

 to test the effect of burying the cocoons or resting stage of the 

 midge, the difference in the number of midges under the traps 

 was so slight no estimate could be made. 



These orchards were examined again June 4, 1896. Only about 

 one-tenth of the fruit on the young orchard was found to be in- 

 jured by the midge maggot. But the same conditions were found 

 in another young orchard which had been cultivated in 1895, but 

 had received no dressing of kainit. In the old orchard, possibly 

 one-tenth of the pears were not injured. 



In the young orchard which had received constant and clean 

 cultivation, but where no kainit had been applied, there were a 

 few large Lawrence trees. These all yielded a fair crop the past 

 year. From one of the trees Mr. Cornell picked six barrels of 

 fine pears. 



Experiments at Blauvelt. 



As already stated a parallel test of remedies was conducted at 

 Blauvelt, N. Y. During the spring of 1894 Mr. S. B. Heusted 

 sowed muriate of potash at the rate of 1,500 pounds per acre 

 around a Tyson pear tree that had been badly infested with pear 

 midge. On April 19, 1895, a cheese cloth trap was placed under 

 this tree. At the same time we thoroughly drenched with kero 

 eene emulsion the ground under some Bartlett trees that had 

 been infested the previous year. A trap was placed over the 

 drenched ground and another trap was placed under a Bartlett 

 tree that had not been treated with any substance. All the or- 

 chard had been cultivated the previous year and sown to rye. 

 So few midges appeared under any of these traps that no con- 

 clusions could be drawn. 



Experiments at Queens. 



On June 20, 1895, a test of salt was started at Queens, N. Y., 

 on the orchard of Mr. N. Hallock. Both table-salt and cracked 

 rock-salt were sown under infested trees at the rate of one bushel 

 per square rod of surface.
