in drills 3 feet apart. One-half of these were harvested 

 at early market maturity (August 1), the balance at full 

 maturity (September 22-23). 



The soil was a medium loam, in mixed grass and clover 

 for the two preceding years. It received an application of 

 farm manure at the rate of about 5 cords per acre on the 

 sod early this spring, and was then ploughed. The fertil- 

 izers used in pounds per acre were : — 



Nitrate of soda, 240 



Acid phosphate, 400 



Sulfate of potash (high grade) , 250 



Tankage, 240 



Dried blood, 100 



These materials were thoroughly mixed and scattered 

 widely in the open furrow before dropping the seed. The 

 seed potatoes were first washed and then treated in formalin 

 solution (8 ounces to 15 gallons water) for two hours. The 

 tubers were budded in a light room after treatment. The 

 planting was done May 4 and 5. The crop was well cared 

 for, and sprayed six times with Bordeaux mixture, to pre- 

 vent blight, of which, however, there was considerable. 

 The development was normal, save for the blight ; and the 

 yields and quality for the most part good. There was prac- 

 tically no scab.
