EXPERIMENTS WITH A VIEW TO CONTROLLING THE DISEASE.

I. At IJ. II. Hatfield's Orchard, Box Hill, near Melbourne 



This orchard, being only about 10 miles from Melbourne, was very conveniently situated 

 for experimental work, and the generous offer of Mr. Hatfield to place it at my disposal was much 

 appreciated. It is situated at an altitude of 317 feet above sea-level, with an easterly aspect. 

 There were several rows of Esopus Spitzenberg, about fourteen years old, suitable for the purpose. 

 Eight trees were chosen for each plot, and, as other varieties were grown among them, it was 

 necessary so to arrange the plots that the eight experimental trees were together. 

 The following is the plan of the arrangement : —

The trees were planted 17 feet x 12 feet, or 213 to the acre, and they bore well in 1910-11. 

 They had all been green manured, peas having been planted in June, with 2 cwt. of superphosphate 

 to the acre to make them grow, and they were ploughed in when in flower in October. The soil is 

 a medium loam, with a good clay about 18 inches beneath the surface, and it is drained with 2-in. 

 pipes 3 feet deep.
