the former purpose the farmer will need some sort of spray pump, for 



the latter some sort of bellows duster, known commonly as "blow 



gun." 



There are many types of spray pumps, but only two or three need 



concern us here. The first is known as a bucket pump, and, as its 

 name implies, it is a spray pump 

 adapted to be used in a bucket. 

 This type of pump is well shown 

 by Fig. 1 . It should be fitted with 

 eight or ten feet of hose and is 

 quite successful for spraying to- 

 bacco in the beds. Pumps of this 

 type, however, are too cumbersome 

 to be used in the fields. There are 

 many kinds of bucket pumps for 

 sale, and they may either be se- 

 cured through a local hardware 

 firm or from the following manu- 

 facturers :

 fields we know of no better type of pump than the compressed- 

 air sprayer, such as is manufactured by the E. C. Brown Com- 

 pany, of Rochester, N. Y. (Fig. 2). Some growers, however, 

 may prefer the knapsack type of sprayer (Fig. 3). Figures 2 and 

 3 show the essential differences between these two types of sprayers.

The compressed-air sprayer is simply pumped full of air, which 

 forces the spray mixture through the nozzle. The knapsack sprayer, 

 on the other hand, must be operated continually to force the mixture
