“The country,” he tells us,[5] “now displayed an aspect different from any we had yet seen; the surface was broken into small separate hills, entirely barren and destitute of vegetation, except some stunted bushes that grew on the declivities, and in the dells, and a few unhealthy trees immediately in the neighbourhood of the villages: the clay was discoloured, and had the appearance of red ochre. We were informed, that the celebrated wells of petroleum, which supply the whole empire, and many parts of India, with that useful product, were five miles to the east of this place. The Seree brought me a piece of stone, which he assured me was petrified wood, and which certainly had much the appearance of it. In walking about, I picked up several lumps of the same, in which the grain of the wood was plainly discernible; it was hard, siliceous, and seemed composed of different lamina. The Birmans said it was the nature of the soil that caused this transmutation; and added, that the petrifying quality of the earth at this place was such, that leaves of trees shaken off by the wind were not unfrequently changed into stone before they could be decayed by time. The face of the country was altered and the banks of the river were totally barren; the ground was superficially covered with quartz gravel, and concreted masses of the same material were thickly scattered. The mouth of the creek was crowded with large boats, waiting to receive a lading of oil; and immense pyramids of earthen jars were raised within and around the village, disposed in the same manner as shot and shells are piled in an arsenal. This place is inhabited only by potters, who carry on an extensive manufactory, and find full employment. The smell of the oil was extremely offensive; we saw several thousand jars filled with it ranged along the bank; some of these were continually breaking, and the contents, mingling with the sand, formed a very filthy consistence.” On the colonel’s return, however, he and Dr. Buchanan rode over to the wells; and their account of their visit is too interesting to be omitted here:[6]—
