August 30 we dug ten hills of potatoes in row of the single eyes, 
cut shallow, and twenty hills in row of the single eyes, ent deep, twenty 
hills of ordinary cuts and twenty hills of whole potatoes used as seed. 
The results noted were as below, multiplying the first set by two in 
order to have comparable. figures : 
No. merch. No. unmerch. Weight of merch. Weight of small 
Seed Used. tubers. tubers. tubers. tubers. 
Single eyes, cut shallow, 14 38 2 lbs. 1 lb. 13 ozs, 
Single eyes, cut deep, 57 72 12 lbs. 10 ozs. 3 lbs. 3 1-2 ozs. 
Ordinary cuts, 55 122 10 lbs, 9 ozs. 6 lbs. 4 1-4 ozs. 
Whole potatoes, 43 134 6 lbs. 13 8-4 ozs. 6 Ibs. 3 38-4 ozs. 
On August 31 dug ten hills and photographed the yields. The fig- 
ures as below, multiplying by two in order to have the figures com- 
parable with the preceding table : 
No. merch. No. unmerch. Weight of merch. Weight of small 
Seed Used. tnbers. tubers. tubers. tubers. 
Single eyes cut shallow, 16 46 1 lb, 2 ozs. 10 ozs.

Ordinary cuts, 38 94 7 lbs. 3 ozs. 3 lbs. 0 ozs. 
Whole potatoes, 42 186 7 lbs. 0 ozs. 6 lbs. 2 ozs. 
A summary of these two tables may be arranged as below:

These results, all in favor of one hypothesis, that deep cutting of 
single eyes furnishes preferable seed for potato growers, receives cor- 
roboration from our field results. This exception will, however, be 
noted; our garden results deal with hills growing; field results with 
hills planted, of which many did not vegetate their seed. 
2. One plat in the garden was surrounded by edgeing, and upon 
land now smoothed by spring rains whole potatoes were laid for seed 
and covered with six inches of straw. There were three rows each ten 
feet long, planted April 18. May 8 showed no signs of sprouting, the 
temperature of soil under straw 48°. June 9 vegetated, the ground 
under the straw very cold and wet. September 21 dug nineteen hills, 
the yield 16 pounds of merchantable and 34 pounds of small potatoes. 
On April 18 we boxed in two plats in the garden. Upon the un- 
stirred land single potatoes were laid in three rows twelve feet long,
