units averaging 469 bushels per acre run 64 per cent. Those 

 averaging 272 bushels per acre gave 88 per cent. Potatoes 

 similar to those used in tuber unit work were sent to Mr. H. E. 

 Talmage, of Eiverhead, L. I., and planted by Mr. Talmage on his 

 farm. Of the 28 lots tested out bj Mr. Talmage, this particular 

 variety from Cortland County gave a yield of 302 bushels with 

 90 per cent seed stock and 10 per cent rejected, according to his 

 figures. 



This chart shows us that the extra heavy yield of 469 bushels 

 over the other two units resulted in a large percentage of potatoes 

 too large to grade, also more of the very smallest size. These pota- 

 toes were all planted in rows 36 inches apart, and 16 inches apart 

 in the rx3w. Had these extra heavy yielders been planted closer 

 together, it is possible that we could have had a larger percentage 

 of seed which would result in large money returns per acre. 



I wish to call your attention to this chart showing how close 

 planting increases the percentage of desirable seed stock: 



The first line gives averages taken from grading on seven 

 farms. iSTote the yield per acre of 310 bushels — total seed 83.42 

 bushels. The value of that seed at 50 cents per bushel, or the 

 price of seed stock for 1914, gives a value of $129.30 per acre. If 

 this entire crop had been sold at the cars, at the ruling price of 

 25 cents per bushel, it would have returned to the farmer $77.50 

 per acre. This farmer has gained $51.80 by growing seed pota- 

 toes at 50 cents per bushel and grading the same according to 

 this standard. Besides this, he has practically 50 bushels of 

 large and small potatoes to be utilized on the farm as food for his 

 stock.
