carts would be the cheapest method of applying the liquid. 

 One acre an hour could be easily watered by a one-horse 

 cart, furnished with a spreader six feet long, that would 

 cover a width on the ground of about eight feet. If 

 the crop is grown in drills two feet apart, the horse would 

 occupy one drill, each wheel of the cart one drill upon 

 each side, and the spreader would cover half a drill upon

each side ; thus four drills would be watered at each 

 passage. If the drills are three or four feet apart, three 

 or two are watered at each passage. In this way one acre 

 would be watered at an expense of about 50 cents, allow- 

 ing $5 for the cost of the necessary horse, two watering 

 carts, and two men. Two carts are needed, as one would 

 be filling while the other is spreading. The cart may be 

 a large cask holding at least 200 gallons, mounted upon 

 wheels with a pair of shafts, the axle being bent to keep 

 the load low down, and a distributing pipe perforated with 

 holes, and curved forward at the ends. Instead of a bar- 

 rel a square tank mounted upon wheels may be used, see
