which sometimes occurs with the use of a heavy disk drill in 

 the loose soil of Aroostook. The seed used was the Prosperity 

 variety and was grown on Aroostook Farm in 1914. 



The results of the experiment calculated to acre yields are 

 given in the table which follows.

These results are decidedly in favor of the seeding with 14 

 pecks. They also indicate that when seeded with 3 or 2>i 

 bushels per acre the yield is as great as when seeded with 4 or 

 5 bushels. The results obtained in 19 14 in the main agreed 

 with those of 191 5. But. as stated above, they are omitted as 

 there were known errors due to accident in 1914. 



From the evidence so far obtained it appears that 3 or 3^ 

 bushels per acre is probably the best rate of seeding for Aroos- 

 took conditions when a medium oat like the Prosperity is used. 

 It must be understood, however, that these experiments must 

 be repeated for several years before trustworthy results can be 

 secured. The results obtained this year may not hold good 

 another year when the seasonal conditions are different. The 

 question, for which an answer is sought, is : How much oats 

 should be sown per acre to obtain the Best yield in a series of 

 years? Consequently, too much reliance must not be put in the
