 gallons. The tank can be lilled in thirty minutes. The cost of the 

 tank was $40 and of the supporting frame $25. The plant consumes 

 3^ gallons of gasoline, at 13i cents per gallon, in a ten hours' run. 

 The water flows back through 300 feet of the supply pipe and then 

 through 800 feet of 2-inch pipe to the land. This 2-inch pipe has 

 an outlet every 22 feet, to which a hose can he connected for sup- 

 plying a movable pipe with water. 



The soil is a light sandy loam 8 inches deep, with a clay and graA^el

witches set 10 feet apart on a movable length of 2-inch pipe, which is 

 mounted every 20 feet on 2-wheeled carriages. Eleven water witches 

 are mounted on 1 00 feet of pipe supported by four carriages, as shown 

 in figure 2, and will irrigate, without moving, a space 110 feet by 10 

 feet. Normally the water witches are run twenty minutes in the same 

 place, but when necessary they are run for as long as an hour. Being 

 mounted on wheels, the apparatus may be easil}^ moved. In the 

 driest seasons it has never been necessary to give the ground more 

 than three thorough irrigations.
