6O COFFEE : ITS CULTIVATION AND PROFIT. 



and thickness of the drum varies, with the depth of the 

 well; as a general rule, for all ordinary lifts, the diameter 

 of the drum may be equal to about one-fifth the number of 

 feet that the water must be raised ; the drum is placed 

 about six feet above the ground, in order to allow the rope 

 to pass over the head of the draught bullock ; the spindle 

 upon which the drum is placed is kept in its upright position 

 by means of two beams, into which it is fixed, which cross 

 each other at the middle, and are supported at the ends 

 or posts placed opposite each other on the outer side of the 

 bullock patch. The bullock walks under the draught bar 

 attached to a curved yoke, which turns on a swivel. In 

 raising water the bullock travels round the upright spindle, 

 thus turning the drum and winding one rope and unwinding 

 the other. If the diameter of the drum is as suggested, 

 i circuits around the path will raise each bucket to the 

 requisite height ; the bullock is turned round, facing the 

 opposite direction, while each bucket is being discharged ; 

 no longer time is required to do this than is needed for the 

 bucket to discharge its contents." " The following may 

 be accepted as a fair estimate of the capabilities of the 

 machine as now ascertained : 



COST PER DAY. 



Rs. A. P. 



Hire for one bullock and driver for one day ... o 8 o 



Interest and wear and tear at 10 per cent, per 

 annum on the capital invested, say Rs; 100, 

 charged over 300 working days ...... o o 6 



Cost of replacing buckets and ropes three times 

 a year, say Rs. 90, charged over 300 working 

 days .................. 049 



Oil, &c. ........... .. ...... oio 



"The cost per day is therefore annas 14, pies 3. When 

 working at the ordinary speed, 90 buckets are raised per 

 hour; each bucket contains 30 gallons when brought to the 

 delivery spout ; the height to which the water is raised
