“ dust-sprayer ” large enough to distribute dry insecticides through 
trees of the size of an ordinary apple tree. 
IN THE WET WAY. 
There are so many manufacturers of spray pumps and nozzles

price of the pumps offered him. 
Fig. 16.— ‘‘Faultless” Hand Atomizer. 
Fig. 16 is an illustration of the “ Faultless Sprayer, manu¬

Fig. 17.—Bellows Atomizer. 
Fig. 17 shows a form of atomizer, having a similar use, also 
sold by Woodason, of Philadelphia.

liquid agitated so the materials in suspension will not settle. A 
common error is to purchase a pump of too small capacity, because

plished in a day with the same help, but with a greater expenditure
