I96 BULLETIN NO. 54. [March, ' 



All working parts should be made of brass. There should be no 

 leather or rubber valves. There should be no stuffing-box, nor should 

 the parts be fastened together with iron bolts or screws. In fact, the 

 brass or alloy pumps are in the end the cheapest, since they are in 

 every way more durable, and are not corroded by the liquids used or 

 by simple exposure. A pump that stands above the barrel or that has 

 any projection whatever is unsteady, especially when there is little 

 solution in the barrel; and moreover it is likely to catch on the limbs 

 and be a nuisance generally. 



Figure 17, p. 197, shows the Eclipse pump manufactured by Morrill 

 & Morley, of Benton Harbor, Mich. It is, according to our experience 

 here, an ideal pump in all respects. All parts that come in contact 

 with the liquid are brass, and there is no stuffing-box. The agitator, 

 too, as seen in the cut, consists of a brass blade, and is a satisfactory 

 means of agitating the liquid. List price, $10 to $18. 



The Pomona pump (fig. 18, p. 197), made by the Goulds Mfg. Com- 

 pany, of Seneca Falls, N. Y. (Chicago Office, 22-24 N. Canal St.) is in 

 most respects similar to the Eclipse, with the exceptions which can be 

 seen by comparing the cuts. This is a pump which we can highly 

 recommend, and which is listed at from $10 to $20. Figure 23 shows 

 a good mechanical agitator which is on the market by the above named 

 company and also by Wm. Stahl of Quincy, 111. Mr. Stahl also has 

 the "Excelsior spray outfit No. 22," which is similar to the Pomona, 

 and is also recommended. 



The Advance Spray pump (fig. 27, p. 199), manufactured by the 

 Deming Company of Salem, Ohio, and for sale in Illinois by their 

 Agents, Messrs. Henion & Hubbell, 61 N. Jefferson St., Chicago, is in 

 every way an admirable machine, and is well spoken of by those experi- 

 ment stations that have made a thorough test of it. The list price of 

 this machine is $18. 



The Kerowater pump (fig. 19, p. 198), for the mechanical mixture 

 of water and kerosene oil, is one of the leading machines of its kind 

 on the market, and is made by the Goulds Mfg. Co., already referred 

 to as the makers of the Pomona pump. List price, $14 to $18.50. 

 The Peerless kerosene sprayer (fig. 26, p. 199), made by the Deming 

 Company, for the same purpose, js also an excellent machine. Its list 

 price is $26 to $35. 



Figure 12, p. 192, shows a handy arrangement for spraying pur- 

 poses, and one that can be fixed up by almost any one. It consists of 

 three barrels of a capacity of fifty gallons each, connected by hose and 

 galvanized iron pipes fitted with stop cocks. These stop cocks enable 

 the barrels to be separated at will, thus carrying three different solutions 

 at one time, or allows the mixtures to drain from one barrel to another.
