the distance taken, the single eye gives the smallest yield, the quarters 

 show a marked increase, and the halves are far ahead of either. 



What is true of the yields is true of the net profits. The results are 

 most decidedly in favor of the half potato, which was the largest amount 

 of seed used. In the averages we have as the yield of the marketable 52.7, 

 88.3, and 112.7 bushels per acre. As to net profits, the averages are $20.43, 

 f33.79, $38.73, or nearly twice as much for the half potato as for the single 

 eyes. 



AMOUNTS OF SEED AND PRICES. 



It may be interesting to note the variation of spring and fall prices in 

 the different years. In the spring of 1891, the price of potatoes reached 

 the highest point in the period of eight years, viz.: ninety-nine cents per 

 bushel. In the fall the price dropped to thirty-one cents, being the widest 

 range of prices for any of the eight seasons. As we have before men- 

 tioned, such a condition would largely determine the relative profits from 

 different amounts of seed. We have added a table showing the profits 

 from this experiment, using the prices which prevailed in the year in 

 which this experiment was conducted. (See table III.)

The quarter potato gives the largest net profit, with the half potato next. 

 The one eye is the lowest, but the whole potato, which gives the largest 

 marketable yield, stands third in the net profit. 



It must be remembered that this was an exceptional season, and that 

 when the price is very high in the spring it is likely to be far lower than 

 the average in the fall. 



Last season the prices varied widely from the average, and a table was 

 given showing the relative profits at the prices actually ruling at that 

 season. The spring prices for that time were more than three times those 

 in the fall. This season the conditions were reversed, and while the seed 

 could be bought for twenty-five cents in the spring, the crop commanded 

 seventy cents in the fall. We exhibit the relative profit of the Early Ohio 

 in Mr. McGee's experiment (page 12) with the actual prices for '92, to 

 show a variation of the opposite direction. (See table IX.)
