class of selects, but as some of the tubers were " nubbj " or de- 

 formed thej were rejected on that account. 



The sixteen rejected hills out of each one hmidred weighed 

 34M2 pounds or at the rate of 180^^ bushels an acre. 



Sixteen selected hills out of the 84 selected hills weighed 64^/2 

 pounds or at the rate of 335 bushels per acre. 



The unselected seed gave yield of 170 bushels per acre. 



The variety was the Green Mountain. 



Farm No. 2. The seed for this experiment was saved the pre- 

 ceding year, being taken from the largest yielding hills as they 

 were dug in the field. However, since part of the seed thus saved 

 froze during the winter, it was necessary to select some from the 

 bin. Every other row of each variety was planted with seed 

 selected from the bin in the usual way, and the alternate row was 

 planted with the field-selected seed by the four-hill method. The 

 land had been made rich with manure some years ago, but when 

 prepared for planting the only fertilizer used was 300 pounds of 

 acid phosphate per acre. The results follow :

Accompanying photographs show yields from one potato of 

 selected seed. These were not much above the average. Four 

 hills dug from another row of the World's Wonder variety showed 

 yield from one tuber of fifty-eight marketable potatoes and two 

 small potatoes, weight 20 pounds, or at the rate of 807 2/5 bushels 

 per acre. These hills were considerably above the average and 

 were not used in results above shown. All of the potatoes were 

 planted in rows three feet apart, eighteen inches in the row.' 



Farm No. 3. Seed used in this experiment was carefully 

 selected for several years. The ground, however, was not well 

 adapted to potato growing. The yield per acre from these selected 

 tubers was 375 4/5 bushels per acre — variety. Sir Walter

Farm No. 4. Seed from first year's selection by the four-hill 

 metliod gave yield of 274 bushels per acre; the same variety, not
