The Advance. — The Advance pump, illustrated in Figure 5, is 

 manufactured by the Deming Pump Company, Salem, Ohio. The 

 list price is §18. 



In appearance this pump is much like the ones that were first 

 placed on the market. The similarity is principally in appear- 

 ance, as many improvements have been made. By detaching the 

 stuffing-box cap the plunger and the lower valve may be taken 

 out of the cylinder. Accordingly the pump need not be taken 

 from the barrel and nearly to pieces when any repairs becomes 

 necessary. The large air chamber, together with the large 

 cylinder, insures a steady spray. The agitator consists of two 

 blades and a plunger that are operated by a connection with the 

 pump handle, as shown in the cut. 



The pump was received so late in the season that it was im- 

 possible to give it a thorough test. It is certainly well made and 

 powerful, and no doubt will prove to be a satisfactory outfit. 



The Empire Queen. — This pump is manufactured by the Field 

 Force Pump Company, Lockport, N. Y. The list price is |9. 

 This is one of the old style pumps that must needs be unbolted 

 and taken from the barrel and pretty much to pieces when any 

 repairs become necessary. Therefore, where* large amount of 

 work is to be done and repairs necessarily become more or less 

 frequent it is likely that the improved forms will be cheaper in 

 the end. In smaller orchards the low price might make it more 

 economical than the more expensive pumps, since the wear would 

 be much lighter. It does good work while in repair. 



The agitator, however, is not as efficient as could be desired, 

 as it has an easy motion and does not agitate the liquid violently 

 as is necessary in order to do the best work. 



The Geiger. — This pump is manufactured by the Geiger Pump 

 Company, Rochester, N. Y., and is listed at §20. It may be 

 classed among the novelties in spraying machinery, and as such 

 only severe testing will determine its value. It works on the 

 principle of the semirotary pumps. All who have tried pumps 

 of this class know that they are very satisfactory as long as the 

 parts fit closely. There are no valves to get out of order; no
