very large proportion was too small to be fit for use. The most 

 uniform size was obtained from the division where the rows were 

 two feet apart. The result of the experiment was as follows : —

I think this result is the most interesting that we have yet 

 obtained, for it not only reduces to something like a demonstration, 

 the superiority of sets over whole tubers, but it shews that the 

 crop will be greater where the distance between the rows is most 

 in accordance with the average height of the potatoe stems ; and 

 that if we take the minimum height, which in this variety is one 

 foot and a half, although the crop may be the most promising while 

 growing, it will, in reality, be smaller than when the branches are 

 less dense. Thus the most uniform crop of stems in this experi- 

 ment was in the division where the row s were one foot and a half 

 apart ; but the crop in that division was less by 1 ton, 3 cwt. 97 lbs. 

 than where the rows were two feet apart, that is, equal to the 

 average height of the stems. 



For the sake of contrasting the produce thus obtained with the 

 crop in the fields of those who cultivate potatoes for the market, I 

 caused the weight in some neighbouring fields to be ascertained by 

 the same men who weighed the potatoes which were the subject of 

 the foregoing experiment.
