694 Report oF THE HoRTICULTURIST OF THE 
The agitator, which is one of the important parts of any sprayer, 
is the weakest point in this machine. It consists of a small blade 
or paddle on the end of a shaft, suspended from the top of the 
tank. By means of cog-wheels it is made to revolve half way 
around, then reverse. This is not sufficient to do the best work. 
Bordeaux mixture can not be too thoroughly agitated. Another 
disadvantage is that there is no way of oiling the main wheels 
except by removing them. In order to do this the endless 
chain must be taken off, which necessitates the removal of the 
sprocket wheels on the crank-shaft. Taken altogether, this is 
quite a laborious task. 
From the driver’s seat, in the rear, the workings of the machine 
can easily be watched and controlled. 
The pipes can be quickly adjusted so as to form a vineyard 
sprayer, as shown in figure 13. Four Vermorels are used, two on 
each side, one above the other and about twenty inches apart, so 
that on level ground the foliage is nearly all in range of the 
spray. Double elbow joints are provided, so that the nozzle can 
be turned at any angle. 
When it is desired to spray orchards the pump-handle is easily 
attached; then, with two leads of hose supplied with bamboo- 
extensions, very good work can be done. 
The size of the tank makes this sprayer especially desirable — 
for the extensive potato grower, and in this capacity does the 
work as well as any potato sprayer now on the market. It is 
well built, strong and powerful. Furnished with Vermorel noz- 
zles it is listed at $70. 
The Columbus Sprayer. 
The Columbus Sprayer, manufactured by W. H. Millspaugh, 
Branchport, N. Y. List price, $60. See fig. 14. 
This machine is designed for spraying vineyards situated on 
rough ground, and especially those located on steep hillsides. It 
is a very compact sprayer, drawn by one horse and requires but 
a short space in which to turn. The barrel is swung between the 
wheels by having short pieces of axle, on which the wheels turn, 
bolted to either side of it. The wheels are low, thus bringing 
the barrel close to the ground, which prevents the machine from 
tipping over when working on steep places.
