" Reviewing these figures as a whole, we observe that the proportion of 

 small potatoes is less from single eyes. 



" Despite the apparent result in favor of whole potatoes, as shown not 

 only by the totals, but by each separate trial, we cannot but notice that 

 even on the highly fertilized plots of 1882, the yield was below that 

 obtained from single eyes in some of the other plats, while in the case of 

 the whole potatoes used as seed, the yields in plat 1 B, five were the max- 

 imum of all our trials. In view of this observation, as also of the uncer- 

 tainty attending plat experiments, we must consider our results as incon- 

 clusive for the purposes of generalization, and conclusive only in the fact 

 that, under the conditions of planting and soil, ordinary cuts and whole 

 potatoes showed a marked superiority in crop over the single eyes used as 

 seed." 



"WHOLE TUBERS VS. CUTTINGS FOR SEED." ^ 



Eighth annnal report, 1889. 



•'The seed tubers used were of the White Star variety which has been grown 

 at the station for several years. These were planted as whole tubers, half 

 tubers, three-eye cuttings, two-eye cuttings, and one-eye cuttings, and 

 with equivalent weights of seed in all rows in which the form was alike. 

 These five diflPerent methods of seeding were arranged in single rows in 

 the order given above, and the set of five rows repeated on each plat. 

 Thus every twentieth acre plat consisted of two rows of each form of 

 seed. When a full stand was obtained each row contained thirty-three 

 hills. Where any hills were missing, the average of those harvested has 

 been taken as their probable yield, and each is thus calculated to a full 

 stand. 



" In order to show the proportion of a full stand secured by each form 

 of seed, the per cent of hills which were missing at harvest is shown in 

 the following exhibit: 



Per cent of hills missing. 



We subjoin a table compiled from the results as given in the report 

 with profits figured on the basis of the average prices as given in the 

 table on page 8.
