greenstone is handsomely porphorytic, and embraces green crystals of feldspar. Portions of this rock are sprinkled with masses of bright sulphuret of iron. Indeed iron in several of its forms abounds. By far the largest portion of it is in the shape of the micaceous oxyde. I searched, without success, for the irridescent specular variety, or Elba ore. In returning from this trip, I found Wolf river greatly swollen by rains, and had to swim it at much hazard, with my saddle-bags heavily laden with the results of my examination. It was dark when I reached the opposite bank: wet and tired I pushed for the only house in sight. As I came to it the doors stood open, the fences were down, a perfect air of desolation reigned around. There was no living being found; and the masses of yawning darkness exhibited by the untenanted rooms, seemed a fit residence for the genius of romance. Neither my horse nor myself were, however, in a temper or plight for an adventure of this kind, and the poor beast seemed as well pleased as I was, to push forward from so cheerless a spot. Four miles' riding through an untenanted forest, and a dark and blind road, brought us to a Mr. Murphy, the sponsor of Murphy's settlement. SCENES AND ADVENTURES IN THE OZARK MOUNTAINS. A.D. 1818 AND 1819. FROM THE ORIGINAL NOTES AND JOURNAL. PRELIMINARY REMARKS. Very little, it is conceived, is necessary to enable the reader to determine the writer's position on the extreme south western frontiers, in the year 1818. He had spent the summer of that year in traversing the mine district, which extends along the right bank of the Mississippi, between the mouth of the Maromeg and the diluvial cliffs south of Cape Girardeau, extending west and south westward to the sources of the St. Francis. In these mineralogical rambles, which were pursued sometimes on foot, and sometimes on horseback, or wheels, he made acquaintance with many estimable men, amongst whom he may name the Austins, father and son, the late Col. Ashley, John Rice Jones, Esq., and many others who are still living, by all whom, his object in visiting the country was cordially approved and encouraged, at all times. He also became acquainted with practical miners, and persons of enterprize who were not only familiar with the settled frontiers, but who had occasionally penetrated beyond them, into the broad expanse of highlands, now geographically known under the term of, the Ozark Chain. Geologically considered, the mine country is but the eastern flanks of this chain, which extends flush to the banks of the Mississippi, and has its terminus in that elevated range of mural cliffs, which form so striking and often picturesque a display, between St. Genevieve and St. Louis. There was, at the time, a general apprehension felt and expressed, by hunters and others who had penetrated those wilds in quest of deer and buffalo, or of saltpetre-earth in the limestone caves, of the predatory
