An improvement in Irrigation. By Lieut. A. Murray McGregor, 

 66th Regiment Native Infantry. 



My principle is, that the greatest power is obtained by keeping the 

 line of draught horizontal, and at the height of the animal's shoulder as 

 is shewn by the mode in which the gigs used in trotting matches are 

 built. This plan was tried at Cawnpoor, by Mr. Stubbs, provisioner, and 

 he assured me\ that he drew one-third more water by my method, than 

 he had upon the old principle ; and that the cattle were less dis- 

 tressed than by the old mode, as it is more laborious to walk up an 

 ascent than upon level ground ; and he had three more wells prepared 

 upon my principle, as it was by far less expensive, and the ground for- 

 merly lost by the inclined plane was saved to the garden, by adapting 

 the hose, (which I do not claim as my invention.) One man will do all 

 the work, and a pair of bullocks will draw the water required in two- 

 thirds of the time required formerly; and the expence is much less. 

 The rope passes over the block or wheel A, and under that at B, by which 

 great power is obtained. 



By the common plan in use the excavate ground becomes at once 

 a dead loss, and the labour of walking up the inclined plane is very 

 great, as it is required to be very steep. I have therefore, by the dotted 

 line B, shewn how the alteration of the present system can be made. It 

 will be requisite, however, to fill up the slope of the inclined plane to the 

 level of the ground as marked at C, but that can easily be done : it would 

 not cost more than three or four rupees. 



N. B. — On the old principle, the driver is obliged to sit on the rope, 

 to keep the yoke on the bullock's necks.
