"As appears, the total yield was directly in proportion to the bulk 

 of seed planted. But in merchantable yield, the two-eye cuttings slightly 

 surpassed the halves and whole tubers. 



" As appears from the preceding table, the whole potatoes yielded 

 more merchantable tubers than the halves, and in another experiment 

 made under precisely the same conditions, not reported in this bulletin, 

 two large whole potatoes to the hill yielded more merchantable tubers than 

 did one. The smaller merchantable yield of the halves and whole potatoes 

 could not, therefore, have been due to an excessive amount of seed. It i& 

 far more probable that it was due to the dearth of moisture, which pre- 

 vented the large setting of tubers in these rows, induced by the 

 abundant nutriment furnished in the seed, from attaining merchantable 

 size, and that with an average rainfall, the heavier seedings would have 

 given the larger merchantable yields. This was the case where the 

 whole tubers of different sizes w^ere compared, as appear from the lower 

 part of the table." 



MASSACHUSETTS. 



Below is a summary of the results of two year's experiments at the 

 Massachusetts Station, condensed from the second and third reports. The 

 results given the table are the averages for three experiments for each of 

 the two years. In two experiments, fertilizers were used; in the third the 

 plat was left unfertilized. In all three nearly the same relative results 

 were apparent. The variety used both years was Beauty of Hebron, and
