variety, the more so since it gives promise of becomiug a valuable 

 market apple, being of excellent quality. 



No. 3. A tree each of Guei and Victoria plums was divided into 

 approximately equal halves, one half of each being thinned July 1st, 

 the other remaining as a check. The fruit of the Guei ripened and 

 was picked Aug. 22, the Victoria Aug. 24. 



The results are shovvn in the followins: table : 



Allowing 12 cents for thinning the Guei and IS cents for the 

 Victoria we have a net gain of 2U and 41 cents respectively for each 

 half tree. 



A distinct advantage gained by thinning is the appreciable 

 decrease in the ravages of fungous diseases, and to a small extent, 

 of insect pests. This is especially noticeable in the case of Monilia 

 or brown fruit rot vvhich often ruins the peach or plum crop in wet 

 seasons, while the specimens of fruit attacked by the curculio were 

 largely removed in thinning. The per cent of fruit affected with 

 Monilia was determined by count at time of picking and may there- 

 fore be taken as a fair estimate of the actual results. 



EXPERIMENTS WITH CATERPILLAR LIME. 



The claims made by the introducers of the two substances known 

 as Raupenleim and Dendrolene are that while they are soft they will 

 catch all insects that may come in contact with the coaling ; that 

 borers or other iiisecis will not lay their eggs on the trunks covered 

 with them and that if put on after these insects have entered they 

 cannot escape ; that they will not injure the most delicate trees to 

 which they are applied 



It will be seen that the value of this material must depend largely 

 upon the length of time it retains viscidity. To determine this 

 point, six young trees each, of apple, pear, plum and cherry were 

 treated July 16 as follows: No. 1, Raupenleim J^ inch thick. No.
