938 REPORT OF THE FARM SUPERINTENDENT OF THE 
2.2 ounces and when the “seed” ends were removed, under two 
ounces. These were planted thus: a row of large tubers whole, 
then a row of the same with the seed ends removed, followed by 
small tubers in the third row, and in the fourth the small tubers 
with seed ends removed. | 
The next four rows were a repetition of the first set of four. 
There were no missing hills at harvest, hence the amounts given 
in the table were actually harvested. 
On comparing the four rows with large seed with the four 
where small tubers were used for seed, the differences in favor of 
the heavier seeding amounts to over thirty-three bushels per acre 
for fifteen bushels of seed and the extra labor of putting in the 
seed and harvesting one load more of crop. If seed and crop 
were both fifty cents per bushel, this increased pay for labor 
would amount to nine dollars, with the possibility of fe 
dollars, should there be no decayed tubers per acre. 
Comparing the yields between whole and cut tubers, four extra 
bushels of seed in whole tubers produced about ten bushels more 
merchantable crop, which, at the same prices, would pay for seed 
and leave three dollars for handling’ the extra crop without the 
labor of cutting seed. 
COMPARATIVE PRODUCTIVENESS OF TUBERS. 
(a.) Selected from general crop, 100 tubers of equal weight.— In 
order to get some result which would be of value in making selec- 
tions or serve as a pointer in making selections of seed tubers to 
avoid the running out of varieties, 100 tubers of equal weight 
were selected and planted as nearly under like conditions as 
possible. The plat devoted to this trial was several times 
severely washed by surface water and when harvested only twenty 
hills could be fairly compared because of the number of decayed 
tubers in all the other hills. 
The yields ranged from three tubers nee ten ounces to ten 
tubers weighing forty-six oune:s, and averaged 10.3 tubers weigh- 
ing twenty-eight and one-quarter ounces. The nearest yields to 
average were four at twenty-eight ounces and one each at vena 
seven and twenty-nine ounces. 
(b.) Best tubers selected from best hills— Planted on same plat 
with above fifty tubers from most productive hills of 1888 which: — 
were fairly even in size and which weighed seven and one-half
