We saw a great many of these mortars during the march that could not have been in use for the last half-dozen centuries, but they are precisely the same as those still used all over India. The driver sits upon the end of the horizontal beam to which the bullocks are yoked; and in cold mornings it is very common to see him with a pair of good hot embers at his buttocks, resting upon a little projection made behind him to the beam for the purpose of sustaining it [_sic_]. I am disposed to think that the most productive parts of the surface of Bundêlkhand, like that of some of the districts of the Nerbudda territories which repose upon the back of the sandstone of the Vindhya chain, is [_sic_] fast flowing off to the sea through the great rivers, which seem by degrees to extend the channels of their tributary streams into every man's field, to drain away its substance by degrees, for the benefit of those who may in some future age occupy the islands of their delta. I have often seen a valuable estate reduced in value to almost nothing in a few years by some new _antennae_, if I may so call them, thrown out from the tributary streams of great rivers into their richest and deepest soils. Declivities are formed, the soil gets nothing from the cultivator but the mechanical aid of the plough, and the more its surface is ploughed and cross-ploughed, the more of its substance is washed away towards the Bay of Bengal in the Ganges, or the Gulf of Cambay in the Nerbudda. In the districts of the Nerbudda, we often see these black hornblende mortars, in which sugar-canes were once pressed by a happy peasantry, now standing upon a bare and barren surface of sandstone rock, twenty feet above the present surface of the culturable lands of the country. There are evident signs of the surface on which they now stand having been that on which they were last worked. The people get more juice from their small straw-coloured canes in these pestle- and-mortar mills than they can from those with cylindrical rollers in the present rude state of the mechanical arts all over India; and the straw-coloured cane is the only kind that yields good sugar. The large purple canes yield a watery and very inferior juice; and are generally and almost universally sold in the markets as a fruit. The straw-coloured canes, from being crowded under a very slovenly System, with little manure and less weeding, degenerate into a mere reed. The Otaheite cane, which was introduced into India by me in 1827, has spread over the Nerbudda, and many other territories; but that that will degenerate in the same manner under the same slovenly system of tillage, is too probable.[3] Notes:
