between them. Four ounces to fifty gallons of water was first 
applied, then the strength increased to five to six and to eight 
ounces to every fifty gallons of water, before satisfactory work was 
done. The strongest solution did not noticeably injure the foliage 
but did kill off the beetles. It did not, however, have much effect 
on the Flea beetles (Haltica Striolata) which attacked the 
foliage, perforating the leaves so thickly as to give them a speckled 
appearance, 
METHODS OF SEEDING. 
The experiments planned to add data to the knowledge already 
gathered in determining the amount of seed which is most 
profitable for the grower to plant, were conducted as follows: 
1. WHOLE TUBERS vs. CUTTINGS FOR SEED. 
The seed tubers used were of the White Star variety which has 
been grown at’the Station for several years. These were planted 
_ as whole tubers, half tubers, three-eye cuttings, two-eye cuttings 
_and one-eye cuttings, and with equivalent weights of seed in all 
rows in which the form was alike. These five different methods 
of seeding were arranged in single rows in the order given above, 
and the set of five rows repeated on each plat. Thus every twen- 
tieth acre plat consisted of two rows of each form of seed. When 
a full stand was obtained each row contained thirty-three hills. 
Where any hills were missing, the average of those harvested has 
been taken as their probable yield, and each is thus calculated to 
@ full stand. 
In order to show the proportion of a full stand secured by each 
form of seed, the whole number of hills which were missing at 
harvest and the per cent of each is shown in the following
