I enclose a report on Darby’s Digger from the _Times_ and _Pioneer_, which shows that it is an instrument possessing the principle we require in deep hoeing, _viz._, turning the earth completely over, and bringing the subsoil to the surface, although of course far too unwieldy, costly, and weighty to be used in Tea. It is, however, the first step in the right direction, as it closely copies spade action; and we may hope that before long a machine with that principle, and capable of being worked in a Tea khet, will be brought out. For light hoeing, last cold weather I procured from Messrs. Vipan and Headly, Church Gate, Leicester, England, two expanding horse hoes, which I worked all the hot weather, and which did their work admirably and at a much cheaper rate than can be done by hand labour. Two of these hoes hoe a 12-acre khet in six days up the lines of Tea and across them, but to make a thorough job it is better to go over the work again. The total cost of this:-- Planted 4′ × 4′ { Pay of boy and man 12 days = 3 6 0 For one hoe { Food of bullocks @ 4 as. per} { diem, Barley @ 24 per Rupee } = 2 0 0 ------- Cost of light hoeing 12-acre khet = 5 6 0 2 ------- Against 10 12 0 ======== Nirrikh for 136 bildars, light hoeing, 240 spaces, 4′ × 4′, per diem @ 0-2-9 each = 23 6 0 ======== Or a saving of more than 100 per cent.
