CHAPTER XV. 



WATER-UFTS. 



CLASSIFICATION. - By far the most important implement 

 for the Indian raiyat is the water-lift. Various forms of 

 water-lifts are in use. The following are adapted for depths 

 of over 25 feet: (i) Mots, single and double, (2) Stoney's 

 Water-lift, (3) Persian wheels and (4) Force-pumps and Fire- 

 engines. The following are adapted for medium depths, i.e. 

 Depths varying from 10 to 25 feet : (i) Paikota, (2) Tera or 

 Dhenkli, (3) Persian wheels worked by hands and feet, (4) 

 Barrakar and Cawnpore chain pumps, (5) Subha Rao's See- 

 saw water-lift, (6) Deck pumps; (7) Centrifugal pumps $ 

 (8) Windmills. The water-lifts adapted for depths smaller 

 than 10 feet are, (i) Sewnis or Swing-baskets ; (2) Irrigation 

 spoons or ladels ; (3) Baldeo balti and (4) Don. 



212. Of all these water-lifts experimented with, the single 

 mot has been pronounced by the authorities in charge of the 

 various Experimental Farms as the best for deep wells, 

 everything being taken into account, and the paikota, the D6n 

 and the Baldeo Balti ^ the best for short lifts. 



213. The single mot (Fig. 36) with a self-delivery tube 

 which will be understood by a reference to the position of 

 the bucket (which is shown in two positions in the figure) 

 costs only about Rs. 25 setting up, and as it does not require 

 such a wide well as the double mot to work it successfully, 

 it is the most suitable water-lifts for fairly well to do cultiva- 

 tors. In the N.-W. P. m6ts are not provided with self- 

 delivery tubes, and there an additional person is needed for 

 emptying the bucket or leather bag when it comes up at the 

 mouth of the well.
