Reasoning from analogy at Jubbulpore, where some of the basaltic cappings of the hills had evidently been thrown out of craters long after this surface had been raised above the waters, and become the habitation both of vegetable and animal life, I made the first discovery of fossil remains in the Nerbudda valley. I went first to a hill within sight of my house in 1828,[14] and searched exactly between the plateau of basalt that covered it and the stratum immediately below, and there I found several small trees with roots, trunks, and branches, all entire, and beautifully petrified. They had been only recently uncovered by the washing away of a part of the basaltic plateau. I soon after found some fossil bones of animals.[15] Going over to Sâgar, in the end of 1830, and reasoning there upon the same analogy, I searched for fossil remains along the line of contact between the basalt and the surface upon which it had been deposited, and I found a grove of silicified palm-trees within a mile of the cantonments. These palm-trees had grown upon a calcareous deposit formed from springs rising out of the basaltic range of hills to the south. The commissariat officer had cut a road through this grove, and all the European officers of a large military station had been every day riding through it without observing the geological treasure; and it was some time before I could convince them that the stones which they had every day seen were really petrified palm- trees. The roots and trunks were beautifully perfect.[l6] Notes: 1. November, 1835. 2. In the Damoh District, twenty-four miles west of Damoh. The name appears to be derived from the 'great quantity of hewn stone (Hind. _patthar_ or _pâthar_) lying about in all directions'. The _C. P. Gazetteer_ (1870) calls the place 'a considerable village'. 3. A peculiar formation, of 'widespread occurrence in the tropical and subtropical regions of the world'. It is ordinarily of a reddish ferruginous or brick-dust colour, sometimes deepened into dark red. Apparently the special character which distinguishes laterite from other forms of red-coloured weathering is the presence of hydrous oxide of alumina in varying proportions. . . . 'Though there is still a great deal of uncertainty about the way in which laterite was formed, the facts which are known of its distribution seem to show that it is a distinct form of weathering, which is confined to low latitudes and humid climates; its formation seems to have been a slow process, only possible on flat or nearly flat surfaces, where surface rain-wash could not act' (Oldham, in _The Oxford Survey of the British Empire_, vol. ii, Asia, p. 10: Oxford, 1914). It hardens and darkens by exposure to air, and is occasionally used as a building stone.
