" The difference iii yield was very marked. The exhibit plainly showed 

 that the greater the quantity of seed potato used the greater teas the 

 product. And this was true not only of the total yield, but also of the 

 product of merchantable potatoes, as distinguished from those so small as 

 to be unmerchantable. The only exception to this result in the whole 

 four hundred average hills, occurred in eight scattered plats (single hills), 

 none of these being on the back rows." 



" The constant decrease of product in all three columns, corresponding 

 to the decrease in quantity of seed potato planted, is too manifest to need 

 comment." 



" This experiment resembles closely in its results similar trials made 

 under the direction of the writer in the years 1885 and 1886, at Houghton 

 Farm, in Orange county, New York. A larger number of varieties were 

 used there, but only three different forms of seed, corresponding to the 

 rows B, C, and D of this year's test, (B, a whole potato as large as a hen's 

 egg; C, a cutting of the usual size; D, a single eye with good-sized piece 

 of potato). In 1885 there were 128 varieties used, 32 standard early kinds, 

 8 early novelties, 61 standard late kinds, and 24 late novelties. In 1886 

 the number of varieties, was 90, classed as 26 early and 61 late. The 

 results in both years at Houghton Farm corroborate the record of the 

 present year at this station."

The bulletin does not state whether the "yields" are total or marketable. 

 If we subtract the amount of seed the result is practically the same since 

 the figures are relative. 



"The general result is thus emphasized: The more seed potato planted 

 the more and better the crop." 



Below are the results from the 40 varieties classified as early and late:
