No. 12, shows the pliers used for putting in place the brass hose 

 coupling No. 13. 



No. 14. Iron couplers to which the hose is attached when a coup- 

 ling is desired. 



No. 15. A pair of pipe tongs, which are very serviceable for tight- 

 ening hose couplings, especially where the union is made to the pump. 



No. 16. Two reducers, used for attaching either ^ or ^ in. nozzle 

 to hose or rod. 



No. 17. Two views of a very handy and easily adjusted hose 

 clamp. 



No. 18. Plug used when one attachment only of hose to pump is 

 desired. 



Fig. 24, p. 199, shows the Success kerosene sprayer, manufactured by 

 the Deming Company, Salem, O., and is a very serviceable pump for 

 kerosene and water when treating small trees infested with scale insects. 

 Price $10.00. 



Fig. 25, p. 199, shows the copper strainer, 12 in. in diameter with 

 brass wire cloth mesh, manufactured by Morrill & Morley, Benton Har- 

 bor, Mich. Price, $1.50. This is one of the indispensable pieces of 

 apparatus used in connection with spraying. Burlap or other cloth 

 strainers should not be depended upon for straining Bordeaux mixture, 

 since lint is almost sure to get into the solution and clog the nozzle. 



The bamboo extensions, such as are seen in Fig. 13, p. 192, are for 

 the purpose of carrying the nozzle up into the tops of the trees, thereby 

 ensuring a more thorough job than could be otherwise done. These are 

 lined with copper tubing, which makes them durable, and are in every 

 way a satisfactory and quite indispensable acquisition to spraying appa- 

 ratus. 



In regard to hose. We find that the y% in. rubber tubing is in every 

 way the most satisfactory hose to use, on account of its lightness and 

 durability. It can be procured for six cents a foot from most dealers. 

 The % in. hose as seen in Fig. 13, p. 192, is too heavy for ordinary use, 

 but is the most durable, especially when wrapped with wire as seen in 

 the cut. Another objection to this hose is the fact that that found on 

 the market for less than 12 to 20 cents per foot is too short-lived to be 

 recommended. The cheaper grades of hose should never be purchased 

 for spraying purposes, as they will prove the more expensive in the long 

 run.
