used, but trials were made with laurel green and arsenate of lead. 

 The laurel green did not give satisfactory results, but arsenate of 

 lead was effective in destroying insects, and no injury to the foliage 

 resulted. The cost of the latter was however considerably greater 

 than Paris green. 



Fertilizers. The following formula was used on each tree, well 

 spread under the branches. 



Large trees — Sulfate potash 5 lbs. Small trees — 2 lbs. 

 " " Nitrate of soda 2 lbs. " " 1 lb. 



" " Acid phosfate 3 lbs. " " 2 lbs. 



In applying fertilizers to fruit trees and plots the quantit}- of the 

 three fertilizing elements, i. e., nitrogen, phosphoric acid and potash, 

 used varied according to the soil, season or condition of 

 growth the previous season. When no fruit was produced and the 

 growth of tree or plant has been large, less fertilizer is applied than 

 when the crop has been large and the growth rather small. If the 

 soil is naturally poor more fertilizer is needed than if it is naturally 

 fertile. 



Pears. 



Number of Varieties 32^ Distance Planted 20x20 ft. 

 The pear crop was very small owing to the fact that most of the 

 trees were young ; most of the varieties were of the newer introduc- 

 tions ; only a few of the standard sorts having been grown for 

 comparison. Many of the young trees were seriously injured by 

 aphides and the i)ear " blister mite," a remedy for which is found in 

 kerosene emulsion. 



Plums. 



Number of Varieties 94, Distance Planted 15x15 ft. 



No fruit on the grounds was so abundant and fine as the plum 

 crop. Of the 50 varieties that fruited 10 were of the Japanese 

 varieties. 



The fruit on all of the trees was thinned, resulting in larger size, 

 and most of the varieties ripened, though some of the fruit rotted 

 badly. Of the varieties most affected by the "brown rot "or 

 monilia were the Lombard, Ponds' Seedling, Yellow Egg, Imperial 

 Gage, Washington, McLaughlin and Spaulding. The fruit on those 

 trees most closely planted or growing in sheltered, rather moist situ-
