Swung in this manner the barrel can be tilted while in motion, 
thus taking the weight off of the horse and preventing waste of 
material when going down hill. The principal claim of merit by 
the manufacturer is for the cart and its combination, as any 
pump can be used. It is furnished with one of the best all 
bronze, single rotary pumps, placed on a frame-work above the 
barrel. The power is taken from the left wheel by means of a 
chain and sprocket wheels. A large air chamber is provided so 
that quite a pause may be made without stopping the flow of 
spray. Itis furnished with a safety valve which prevents any

strain on the hose when light work is being done. The pump 
may be operated with a hand crank by throwing the machine out 
of gear. An attachment for holding the nozzles is supplied when 
desired, but when spraying on uneven ground the work can not 
be economically done unless the nozzles are held in the hand 
_and the spray directed where needed. Two leads of hose ten feet 
long are furnished for this purpose. On the end of each hose is 
-a three-eighths inch brass tube about eighteen inches long; at 
each end is placed a Vermorel nozzle. With the four nozzles 
two men will cover a large area of vines in a day. 
For spraying vineyards on steep hillsides this is the best power 
sprayer we have seen.
