Now, in regard to the cost, tlie chemicals were all purchased at whole¬ 
sale rates, as follows: 
Sulphate of copper.per pound.. $0. 06| 
Best lime..per barrel.. 1. 25 
Aqua ammoma...per pound.. 0.05 
Carbonate of copper, concentrated solution.per quart.. 0.16£ 
Using the Japy pump and Vermorel nozzle, it is estimated that the 
cost of labor in applying the remedies was $2.50 per acre for five appli¬ 
cations, or one-half a cent per vine. The number of gallonsof the various 
solutions used per acre was, on an average, 44. Taking these figures as 
a basis, we have the total cost of treating the various sections as fol¬ 
lows :

It is seen from the foregoing tables that the largest yield per vine 
(3.48 pounds) is in section 11, where the Bordeaux mixture, containing 
0 pounds of copper and 4 pounds of lime, was used. This section also 
received the winter treatment. By comparing this yield with that of 
section 1, where the same mixture was used but the winter treatment 
omitted, it is seen that there is a gain in favor of the winter-treated 
section of nearly a pound per vine. Now examine the figures in section 
4, treated with the Bordeaux mixture, containing 4 pounds of copper
