occasions of which arsenate of lead was added to the mixture. The 

 crop was harvested October 6th and 7th. No extra large tubers were 

 in evidence on any of the plats. The potatoes on all of the plats were 

 free from scab, medium in size, smooth and clean. Dry matter de- 

 terminations were made on the same day that weights were 

 recorded. 



The following table gives a summary of yields of dry matter 

 on an acre basis:

Eight plats were used and received fertilizer at the following 

 rates per acre:

 and disked in,) Nitrate of Soda 150 pounds, Tankage 200 pounds. 

 Sulfate of Potash, high grade, 200 pounds. Acid Phosphate 400 pounds. 



Plats 3 and 5. New Mineral Fertilizer, 1 ton. 



Plats 1 and 8. No fertilizer or lime. 



Plats 2 and 7. Stonemeal, "O" grade, 1 ton. 



The fertilizer was applied as per schedule, the land fitted and 

 crop sown May 16th. Although the crop did not suffer particularly 

 from rust, yet it was thought best to cut and dry the same before 

 maturity. The oats were cut September 8th, weighed September 

 10th, and dry matter determinations made.
