Seite 137 - ... on the drills in the form of mud, which is an evidence that it contains salt. There is a continual discharge of carbonated hydrogen gas from the well ; and also from the bed of the creek on which the well is situated, at various places for the distance of half a mile. This gas is highly inflammable, and where there is a free discharge of it, it will take fire on the surface of the water, on the application of a lighted stick, or the flash of a gun, and continue burning for days, unless put out...
Seite 137 - and besides is subject to such tremendous explosions of gas, as to force out all the water, and afford nothing but gas for several days, that they make but little or no salt. Nevertheless the petroleum affords considerable profit, and is beginning to be in demand for lamps, in workshops and manufactories.

Seite 128 - Lick," as it was called, was just at the river's edge, 12 or 14 rods in extent, on the north side, a few hundred yards above the mouth of Campbell's creek, and just in front of what is now known as the " Thoroughfare Gap," through which, from the north, as well as up and down the river, the Buffalo, Elk, and other ruminating animals made their way in vast numbers to the lick. I may mention en passant that so great was the fame of this lick, and the herds of game that frequented it, that the great...
Seite 163 - The reason why natural gas should collect under the arches of the rocks is sufficiently plain, from a consideration of its volatile nature. Then, too, the extensive fissuring of the rock, which appears necessary to form a capacious reservoir for a large gas well, would take place most readily along the anticlinals where the tension in bending would be greatest.
Seite 131 - ... is done, as one of the standard appliances for the purpose for which it is used. This seed-bag is made of buckskin, or soft calf-skin sewed up like the sleeve of a coat or leg of a stocking ; made 12 to 15 inches long, about the size of the well hole and open at both ends ; this is slipped over the tube and one end securely wrapped over knots placed on the tube to prevent slipping. Some six or eight inches of the bag is then filled with flaxseed, either alone or mixed with powdered gum tragacanth...
