The Best Two Spraying Outfits

hard matter for the amateur to 

 tell just what kind of spraying 

 outfit to buy. 



THE "knapsack PUMP" 



For garden work on a small 

 scale where one does not care to 

 spray anything taller than six feet, 

 the knapsack pump is more satis- 

 factory than any other small pump 

 I have ever used. This is fastened to the back by means 

 of leather straps (Fig. 28) and is very handy for spray- 

 ing potatoes, roses, grapes, etc., but will not do for 

 large fruit trees. 



The ordinary bucket pump is very unsatisfactory.
