In the remainder of this letter, I shall give you an account of a natural curiosity, and rest assured I shall give you nothing exaggerated. Three weeks since A.B. Jones, Esq., George Jones, his brother, and myself mounted horses, taking with us a companion, and directing our course southwest from this place, through a pathless wilderness for thirty miles until we arrived on the bank of Duck Creek. On the north-east bank of said creek, in latitude 38 deg. 39 min., we found an Oil Spring. This is one of the greatest curiosities of nature. It is in the form of a well. I sat myself down on the brink of it to make observations, which shall be given as nearly as I can describe with my pen. The well is about seven feet from the edge of the creek. It has been accurately ascertained to be forty feet deep from the surface of the ground to the bottom, and is three feet in diameter at the tip. A piece of a large buttonwood tree has been hollowed out and placed for a curb on the top to prevent people from falling into it. The oil boils continually like the boiling of a large soap kettle. The quantity which rises is about five barrels a week. I found an old ladle lying near, which I dipped into the oil and forced it down into the water, and found the oil three feet deep. I drew with the ladle as fine salt water as ever I tasted in the ocean. I then tried the goodness of the oil and found it to burn clear and bright. A boy, a few weeks since, in order to ascertain whether oil would burn on water, touched a firebrand to that on the creek and instantly it was inflamed.
