On the demonstration plat there was a total of 827 larve, with 
3,220 for the one-spray plat and 9,038 on the unsprayed block. The 
notably less number on the demonstration plat is probably due to 
the destruction, from later sprayings, of larvee entering at the side, 
which tendency, as stated, became very marked after the injury to 
the fruit by hail. 
THE PLUM CURCULIO. 
The effect of the treatments in the W. S. Ballard orchard in con- 
trolling the plum curculio on Plats V, VI, and VIII is shown in 
Table XI. Egg and feeding punctures are combined in the table 
under ‘‘No. punctures.”’
