Seite 137 - Coal is also found, though in less considerable seams, along the valley of the Little Kanawha. Near Hughes' river, one of its tributaries, it is very abundant; and in the same neighbourhood, springs of petroleum, or rock oil, have been discovered. North and west of this stream on the ridge, selenite or crystallized gypsum is said to occur, though at what place and to what extent, we are not informed.
Seite 165 - Book of Nature," after describing the barren state of society in the middle ages, says, " we have thus rapidly travelled over a wide and dreary desert, that, like the sandy wastes of Africa, has seldom been found refreshed by spots of verdure, and what is the moral ? That ignorance is ever associated with wretchedness and vice, and knowledge with happiness and virtue. Their connections are indissoluble ; they are woven in the very texture of things, and constitute the only substantial difference...
Seite 136 - ... possessed by the region before us. Whatever valuable materials lie included in the strata of the district, coal, salt, limestone or iron ore, the horizontal position alluded to keeps them near the surface, or at an accessible depth, over enormously wide spaces of country, while the trough-like structure of the valleys, and their great depth, exposes the edges of many of these deposits to the day, under positions in which mining is the easiest imaginable, and with an extent of development not...
Seite 56 - Traced transversely, it is seen to dip beneath the cretaceons greensand at various points in New Jersey, Delaware and Maryland, but in Virginia disappears in its eastward dip beneath the Eocene tertiary. How far we may consider this group of sediments in Maryland, Delaware and New Jersey, as merely a continuation of the Virginia formation above described, can be determined only by further investigation. But the discovery in them at Baltimore, by Prof.
Seite 165 - I am persuaded that a geological survey would tend to correct. I met many wagons loaded with sulphate of lime (gypsum) from Nova Scotia, being taken to the interior to be used as a manure ; but I did not see one wagon employed to bring carbonate of lime...
Seite 56 - ... the flanks of the Blue Ridge, and in the Appalachian valleys beyond. In the belt partially occupied by the surface deposit here referred to, there is exposed another group of strata, with which, at first view, the sandy and argillaceous layers of this formation might readily be confounded. These are the silicious, argillaceous and pebbly beds, which, underlying the tertiary in Virginia, and the wellmarked...
Seite 72 - And that the Director and members of the Geological Survey shall have no personal or private interests in the lands or mineral wealth of the region under survey and shall execute no surveys or examinations for private parties or corporations...
Seite 136 - Virginia is characterized throughout by geographical features of great simplicity. The surface of the region is undulating, and towards its south-eastern limit, mountainous ; but the loftiest hills rise in gently swelling outlines, and no very prominent peaks tower in acute and ragged lines, to denote that the strata have been subjected to violent convulsive and upheaving forces. Everything bespeaks it to have been at one time an expanded plain gently tilted from the horizontal position, so that...
Seite 164 - I determined upon respectfully suggesting to your excellency the expediency of a topographical, geological, mineralogical and orgetological survey of Virginia. Should the enlightened representatives of the freemen of your state concur in this opinion, it will redound to the honor of all concerned by the encouragement it will give to the study of the natural sciences; by the enhancement in...
Seite 165 - The mountain ranges of Virginia are more numerous, and the valleys consequently narrower than in Pennsylvania, but some of them are very interesting. The great valley, as it is sometimes called, or par excellence, the valley, situate between the Blue Ridge and the North and Alleghany mountain, is by far the most extensive.
