The potatoes were dug October 23 and sorted into two grades— 
sound tubers of marketable size and sound tubers below market- 
able size. No account was taken of rotten tubers. The yields are 
shown in Table XIII. 
In each of the first three sections of the experiment the soda 
bordeaux gave slightly better results, while in the last two sections 
lime bordeaux was considerably in the lead so that on the average 
there was a difference of g bu. 20 lbs. of marketable tubers per 
acre in favor of the lime bordeaux. The average yields for the three 
kinds of treatment were as follows: 
Sprayed with lime bordeaux, 202 bu. 10 lbs. marketable tubers per acre. 
Sprayed with soda bordeaux, 192 bu. 50 Ibs. marketable tubers per acre. 
Unsprayed, 81 bu. 50 lbs. marketable tubers per acre. 
The rows sprayed with lime bordeaux outyielded the unsprayed 
rows by 120% bushels per acre. The unsprayed rows died early 
from blight and bugs. Although the unsprayed rows received the 
same amount of paris green as did the sprayed rows and it was 
applied on the same dates and with equal thoroughness, they were, 
nevertheless, much more severely injured by bugs than were the 
sprayed rows. ‘This is only another example of the well known 
fact that bordeaux assists in the control of bugs. 
No attempt was made to determine accurately the loss from rot 
in this experiment. It seems to be about the same as in the ten- 
year experiment. (See page 128). In this respect there was appar.
