    bably the Bullock Power at the Powder Mills and Mint alone at present costs 8 000 Rupees per annum, which is the Interest of 1,60,000 Bupees, and with the command of a cheap power probably, its more general application to other purposes would result, and even in your establishments, it may be substituted for manual labor. To enable you to form a calculation, I am desired to state that water for power could be supplied at say, 6,000 cubic yards for 1 Rupee, which if falling through 6 feet, would give a net power of 40,000,000 lbs. through 1 foot, equal to 13°Horse Power of a Steam Engine for 1 hour, and the cost would be 1* Anna per Horse Power per hour, but as the water would of course not be con- sumed by passing over a wheel, and as it would still be available for all ordinary purposes, some reduction in the cost may be effected. The cost of manual labor may be taken at 2,000 lbs. X 60 minutes X 10 hour8 — 1,200,000 lbs. through 1 foot per day, and valued at 3 Annas which is 8 Annas for 1 Steam Horse Power for 1 hour, 1 Bullock lbs per day. d Bunock power may be estimated at about 0,000 lbs. by 60 by 8 =2,880,000 per 4 Annas. 4 Annas per Steam Horse Power per hour. In making your calculation, it would be advisable to include not only the expenses of the Bullock Department, but also the losses from animals dying or becoming unserviceable, and also ascertain to the mechanical force in the differ- ent Departments of your Manufactory to which the labor of the Bullocks is applied, and compare it with the number of Steam Horse Power to which the labor of the full compliment of the bullocks is equivalent ; also to contrast the total expenses incurred for the keep of the animal during the whole year, with the charge of the Water Power for only the number of working days, for al- though the water will require to be stored up as if to be used for the whole year, yet by its being known to be disused during a certain period of the year, holidays, Sundays, &c, the water not then required can easily be used for other purposes. Any extra expenses or reduction connected with the machinery for Bul- lock and Water Power to be noticed. The cost of applying the water to work the present apparatus will not be great. The advantage of applying an increased power when urgently required, in diminishing the Establishment, should also be calculated, as well as the supe. riority of the power in the work to be done, and any modifications in the other work now performed by manual labor to be taken into consideration. I have the honor to be, Sir, Your obedient Servant, (Signed) A. H. HOPE, 5th November 1852, Acting Secretary.
