soaked and adding to the dead weight of the outfit. The capacity 

 varies from 50 to 250 gallons, the latter being as much as a pair of 

 horses can ordinarily draw. They are generally locally made, as 

 the cost of shipping them any great distance is considerable. But 

 there are numerous exceptions to this statement. 



Spraying tanks are commonly distinguished as horizontal and up- 

 right cylindrical. The horizontal tanks are subdivided into those 

 with flat and with half-round bottoms (see Figs. 39, 40, 44), the 

 former being only occasionally met with. The bed pieces in the hori- 

 zontal half-round form consist commonly of two heavy pieces of 

 hardwood timber resting on the edges of the wagon bolsters on each 

 side. See Fig. 39. Some outfits do not use bed pieces but have sim- 

 ply semi-circular false bolsters for the tank to sit in, as in Fig. 40. 

 This gives an advantage in turning around, since the wheel can be 

 cramped closer to the tank, but with steam outfits there is an at- 

 tendant disadvantage, in that the boiler must be hung from the rear 

 axle. 



KINDS OF SPRAYING OUTFITS. 

 bucket outfits. 



A bucket-pump outfit consists essentially of a common force pump 

 set in a pail or bucket, and such the simplest forms of these outfits 

 are. In this case a pail is used with a pump held in place by the foot. 

 A step forward was taken in the development of the apparatus when 

 the pump was firmly attached to the pail, thus relieving the operator 

 of the task of holding it. Then the bucket was made larger to hold 

 five or eight gallons, or as much as a man could conveniently carry. 

 Galvanized iron was used in its manufacture instead of wood and a 

 lid was added to keep the liquid from slopping out. Some outfits 

 have added a smaller vessel or can inside or outside the larger to 

 contain oil. For this purpose an appropriate modification of the 

 pump is necessary.
