The bench to which the pump is fastened is made to fit the round of 
- the barrel and kooks down to the sides and ends, as shown in the plate. 
The pump is bolted to this bench and then inserted through an opening 
in the barrel. It is not a matter of any importance how the barrel or 
tank is supported on the boat or sled, but a skid can easily be made 
consisting of 4 by 4 inch scantling 2 feet, 6 inches long. The bottom 
pieces are placed 18 inches apart and the top pieces 13 inches apart 
and bolts are put through each corner. The top pieces should be 
rounded on the inner side to meet the rounded sides of the barrel. To 
the bottom of the pump cylinder a flexible hose is fitted of sufficient 
length to reach to the bottom ofthe tank. Thissupply pipeshould always 
be covered with a strainer. The method of drawing the tank over 
_ the field by means of a flatboat is cheap and convenient. A barrel 
nse 
mounted upon runners can easily be drawn by one horse over cultivated 
ground. All tanks should be provided with a strainer through which 
the liquid is poured. This is of considerable importance and will help 
very much to prevent the clogging of the nozzles. The ordinary spray- 
ing pumps are fitted up with one-half to three-quarter-inch heavy hose; 
this, however, is too heavy, and, a practicable length of it can not be 
used. It is better to buy a good cloth insertion three-eighths or one- 
quarter inch rubber tubing, which will answer every purpose and will 
be light enough to be elevated on a pole (a bamboo fishing-rod will 
answer the purpose and will be the lightest substance which can be 
found), as Shown in the plate. 
To revert once more to the subject of nozzles, it is very important to 
spray the undersides of the leaves and the undersides of the lower 
leaves can not well be reached by an end-discharge nozzle like the Climax. 
The Cyclone or Riley nozzle is a side-discharge nozzle, and by its use 
this kind of spraying can be readily done. 
It will be somewhat expensive to construct an apparatus like the 
above, but it will last for a number of years if well made, and will be 
applicatle to many other uses. 
In small hop yards a knapsack pump will answer the purpose quite 
as well. Three very good and substantial ones are on the market, as 
follows: The Galloway Sprayer, manufactured by Albinson & Tru- 
sheim, 2026 Fourteenth street, Washington, D. C., for $14; the Knap- 
sack manfactured by the Field Force-pump Company of Lockport, 
N. Y., sells for the same price, and the Eureka, made by Adam Weaver, 
of Vineland, N. J., for $21.
