Potatoes. —The land upon which these potatoes were grown, was sward 
upon which no crop had ever before been raised, plowed in fall of 1868. 
Soil, clay loam with clay subsoil. Marked with a plow three and one-half 
feet apart. Planted one foot apart in row, May 4th and 6th. The seed was 
covered uniformly three inches in depth, and was prepared as follows:

June 1st, plants coming up. June 12th, cultivated once in a row and 
sowed on eshes at the rate of thirty bushels per acre. The same relative 
growth of tops was observed that was noticed in 1868, viz: No. 1 much the 
largest, Nos. 8 and 6 next in size. Cultivated second time, and hoed July 
6th. Dug October 11th and 12th, yielding as follows:

No. 1 yields most per acre, yet gives smallest increase for one pound of 
seed. 
It will be noticed that generally, although not uniformly, as the yield 
increases, the rate of increase for one pound of seed diminishes. 
As in last year’s experimant, the size of the seed seems to affect the size 
of the product but slightly. The single eyes gave the smallest yield, as be¬ 
fore, but the difference was much less marked than last year. With the 
exception of plat No. 1, which gave the largest potatoes, the size was very 
uniform throughout. No. 4 appeared to contarin fewer potatoes that were 
very small than any other plat. The yield corresponds to the comparative 
growth of tops. No. 1 largest, Nos. 3 and 6 next in order.
