EXPERIMENTS WITH A VIEW TO CONTROLLING THE DISEASE.

was reported that — " We have now 600 kinds of apples growing upon the dwarf system, and several 

 kinds of stocks have been tested in various ways, viz. : — (1) Paradise root stock only; (2) Paradise 

 root with Winter Majetin as intermediate ; (3) Paradise root with Northern Spy as intermediate ; (-1) 

 Northern Spy root with Paradise as intermediate ; (5) a dwarf blight-proof stock obtained from 

 the Siberian Crab was used. The most satisfactory results were obtained from the fourth test, 

 viz., Northern Spy root with Paradise intermediate, the Paradise intermediate being grafted on to 

 the Northern Spy, 4 or 5 inches above the ground, and the variety 4 inches above that again, leaving 

 4 inches Paradise intermediate." 



The dwarf trees are all planted 6 feet by G feet, and the cultivation consists in 

 hand digging the soil and hoeing between the rows and around the trees all through the 

 season. The manure applied in 1910 was 1 ton of tobacco stems and L0 tons garden litter 

 and stable manure per acre. In 1911, 20 tons stable manure and 5 cwt. lime were applied 

 per acre. 



The entire orchard is underdrained with tile drains. The system of pruning has been light 

 for the past four years, but previously it was rather heavy. 



In the portion of the orchard where the dwarf trees are, it is alluvial soil and silt below., and 

 in the other portion it is a clay loam. 



The chemical and mechanical analyses of the soil are as follows, No. I being the clav loam 

 and No. 2 the alluvial soil.
