for Indian use tor small depths (up to 6ft.), its lifting capa- 

 city^ being 10,000 gallons per hour. (2) Next to it comes 

 the swing-basket which in the hands of dexterous coolies 

 will lift about 2,000 gallons of water per hour from a depth 

 of 10 ft. (3) For medium depths, either a double or triple 

 series of dons, or the lever and bucket-lift (iera) is the r best. 

 500 gallons of water can be raised per hour : with tera. (4) 

 For great depths, the Single and Double mot and the Egyp- 

 tian or Punjab pattern Persian wheel are the best. The mots 

 will give about 1,000 gallons per hour, and the Persian wheel 

 about 500 gallons. Considering the cost, the Single mot is 

 to be preferred to all others for great depths, and to adapt 

 ordinary ring Wells of only 3 ft. diameter, and to avoid spil- 

 ling of water, the bucket can be made to slide up two steel 

 ropes stretched vertically from the bottom of the well up 

 to the beam whence the pulley is suspended. To irrigate 

 an acre of land, 50,000 gallons are required for clay-soils, 

 and 100,000 gallons for sandy loams. The latter quantity 

 is equivalent to about \ an inch of rain-fall, which is enough 

 to soak thoroughly 6 inches of soil. For more thorough irri- 

 gation, double the above quantities may be allowed, viz., 

 100,000 gallons per acre for clay-soils and 200,000 gallons 

 per acre for sandy loams, and the arrangements needed for 

 irrigating a particular locality with any of the water-lifts 

 or pumps described above, can be worked out for every 

 particular locality.
