 sprocket gear attached to one of the wagon wheels. Those with 

 large capacity should be supplied with trucks having wade tires. 



horse-power OUTFITS. 



Horse-power outfits differ in principle from the hand-power tank

 secured by gearing the pump to a sprocket wheel attached to a wheel 

 of the rig or to the axle. There are several forms of horse-power 

 sprayers on the market. Those which are designed for field crops or 

 for vineyards will be discussed under separate headings, as also will

The horse-power outfits designed for the orchard do good work 

 with comparatively small trees, but when the tree is so large that it
