In this experiment, the pinching appears to have been positive] y 
detrimental to the yield of tubers. 
Are some Varieties more Subject to Rot than Others ? 
From the table giving the yields, ete., of the first planting, it 
appears that there is little uniformity in the per cent. of decay in 
the yields from the large and small tubers, in the same varieties. 
Thus the crop of the large tuber of the Boston Market had no rot- 
ten potatoes, while sixty-five per cent. of that from the small tuber 
was rotten. In the Harly Telephone, on the other hand, the crop of 
the large tuber had more than twice as much decay as that of the 
small one. As these plantings were grown under, as nearly as possi- 
ble, equivalent conditions, it would appear at first thought that the 
amount of decay is less a question of variety than of some other con- 
siderations. 
A comparison of the percentages of decay of the varieties of the 
second planting, with those of the same varieties in 1883, however, 
suggests a different conclusion. We present ten each of the varie- 
ties in the second planting that decayed most, and that decayed 
least, giving also the percent. of decay for each in 1883, as follows: 
Pr cent, Pr cent. Pr cent. Pr cent. 
of decay. of decay. of decay. of decay. 
Most decay. 85. 1883. Least decay. 1885. 883.

It is evident that the varieties that decayed least in 1885, decayed 
very little in 1883, while those that were a total loss in 1885, were 
also quite largely decayed in 1883, facts which suggest that the 
amount of decay may be in some degree due to variety. 
It would be interesting to discover whether or not the tendency to
