“The country here,” he says,[52] “is a series of sand-hills and ravines—the latter, torrents after a fall of rain, as we now experienced, and the former either covered with a very thin soil, or altogether bare. The trees, which were rather more numerous than we looked for, did not rise beyond twenty feet in height. The surface gave no indication that we could detect of the existence of the petroleum. On the spot which we reached, there were eight or ten wells, and we examined one of the best. The shaft was of a square form, and its dimensions about four feet to a side. It was formed by sinking a frame of wood, composed of beams of the _Mimosa catechu_, which affords a durable timber. Our conductor, the son of the Myosugi[53] of the village, informed us that the wells were commonly from one hundred and forty to one hundred and sixty cubits deep, and that their greatest depth in any case was two hundred. He informed us that the one we were examining was the private property of his father—that it was considered very productive, and that its exact depth was one hundred and forty cubits. We measured it with a good lead-line, and ascertained its depth to be two hundred and ten feet, thus corresponding exactly with the report of our conductor—a matter which we did not look for, considering the extraordinary carelessness of the Burmans in all matters of this description. A pot of this oil was taken up, and a good thermometer being immediately plunged into it, indicated a temperature of ninety degrees. That of the air, when we left the ship an hour before, was eighty-two degrees. To make the experiment perfectly accurate, we ought to have brought a second thermometer along with us; but this was neglected. We looked into one or two of the wells, and could discern the bottom. The liquid seemed as if boiling; but whether from the emission of gaseous fluids, or simply from the escape of the oil itself from the ground, we had no means of determining. The formation where the wells are sunk consisted of sand, loose sandstone, and blue clay. When a well is dug to a considerable extent, the labourers informed us that brown earth was occasionally found.... The petroleum itself, when first taken out of the well, is of a thin watery consistence, but thickens by keeping, and in the cold weather it coagulates. Its colour at all times is a dirty green, not much unlike that of stagnant water. It has a pungent aromatic odour, offensive to most people.... The contents of the pot are deposited for a time in a cistern. Two persons are employed in raising the oil, making the whole number of persons engaged on each well only four. The oil is carried to the village or port in carts drawn by a pair of bullocks, each cart conveying from ten to fourteen pots, of ten viss each, or from 265 to 371 pounds avoirdupois of the commodity.... The price, according to the demand, varies from four ticals of flowered silver to six ticals per 1,000 viss; which is from
