Page 270 - Cornel ison & Son. The clay is obtained on the road from Waco to Cobb Ferry, about a mile and a half east of the junction of this road with the road from Waco to Bybeetown. The pit is located northwest of the road corners, at which the road across Falling Brook joins the road from Waco to Cobb Ferry. The thickness of the clay bed in the clay pit averages about five feet. The clay overlies the Black Shale. The clay is brought to the shop and put in a ring pit. This ring pit usually consists of a circular...
Page 84 - Another thick section of Devonian limestone occurs three miles southwest of Cartersville, where the road to Crab Orchard crosses the headwaters of Harmon creek. Here the Devonian limestone is seventeen feet thick. Half way between this locality and Crab Orchard the thickness of the Devonian limestone is only six feet, so that the Devonian limestone appears to become thinner from both areas toward this middle region. . . . Directly north of Berea the thickness of the Devonian section is thirteen and...
Page 1 - I have the honor to herewith transmit for publication a bulletin, prepared by Professor Aug. F. Foerste, on the Silurian, Devonian and Irvine Formations of East-Central Kentucky, with an account of their clays, limestones, mineral waters and water horizons. The report is divided into three parts. Part I. deals with the classifications of the several formations, and with the geographic distribution of their subdivisions, in accordance with the better knowledge of them that has been acquired since...
Page 263 - ... because of the pleasant tints they assume in calcination. They owe these tints to their considerable proportion of iron oxide, which, together with their large proportion of potash, renders them unavailable as fireclays. This very circumstance, however, may fit them for stoneware...
Page 140 - Some of tiie layers are sparingly crinoidal, but with crinoid stems or segments of stems of small diameter. The lowest layer of the Brassfield bed includes numerous rounded, black pebbles and grains, possibly phosphatic, varying in size from an eighth to a quarter of an inch; a few equal even as much as an inch in diameter. Immediately below, the top of the Ordovician is exposed. The upper part of the Brassfield bed exposure contains the following fossils: Orthis...
Page 275 - The brick yard run by Berea College for its own use and for the employment of some of the college students, is situated about a mile north of town. The clay is obtained from a pit situated northeast of the brick-yard. About three inches of soil are removed, and the underlying clay has a thickness of about three and a half or four feet. It overlies Black Shale. A narrow track with cars is used to haul the clay from the pit to the plant, and then, by means of a cable run by steam, up an incline to...
Page 225 - ... danger of the temperature rising sufficiently to approach complete fusion, which, of course, would cause the articles formed from the clay to lose their shape, stick together, and become altogether useless. High-grade terra cotta work is now made from a mixture of fire-clays which burn to a buff color. The Silurian clays here under discussion are not fire-clays, and they would not burn to a buff color. Clays containing 5 per cent...

On the hill two hundred yards north of the home of Dr. Freeman. Two miles southeast of Bobtown, on the east side of the Big Hill pike, north of Joe Lick creek. Geological position: Collected by John R. Procter, and stated by him, to occur beneath the Corniferous limestone. The bed is six or more feet thick, and contains gypsum. Locality: RS-21. Probably belongs...
Page 248 - Sodium chloride is the most common ingredient of such waters, but magnesium sulphate (Kpsom salt) and sodium sulphate (Glauber salt) occur in most waters of this class. Sodium carbonate, on the contrary, occurs only in very small quantity as a rule. Sodium chloride waters are said to be useful in stimulating the gastric mucous membrane, in increasing the appetite, and in getting rid of excessive amounts of secreted mucus. The best results are obtained in gastritis. Saline waters containing considerable...
Page 219 - From Irvine, along the road an eighth of a mile north of Estill Springs, and an eighth of a mile south of James Harris; Estill county. Geological position: Lulbegrud clay, collected from two to thirteen feet below the massive two-foot layer which forms the base of the Waco formation. This is the middle clay of the Crab Orchard bed. Collected by AF Foerste, 1904. Analysis, sample...
