Page 224 - Shell medium size; apex high and almost straight above the anterior line of the shell; the shell slopes from the apex and arches a little toward the posterior part of the shell, but laterally and in front it descends abruptly to the margin; transverse section ovate; surface marked with fine, close, concentric lines and a few coarser ones, all of which appear to indicate lines of growth, instead of surface ornamentation; internal scars unknown. The high apex and anterior portion of it seem to distinguish...
Page 18 - Railway. The lake is five-eighths of a mile long by three-eighths of a mile wide and of a regular oval shape. On the south the country is rolling or flat but on the north rises one of the most abrupt ranges of hills occurring in the drift region of the State. In the words of Dr. Dryer:* "They are as rough and irregular a pile of gravel knobs as can be found in Indiana, rising 150 to 200 feet above the lake, with a southern descent almost too steep for a horse and wagon. The range is two and a half...
Page 158 - spontaneous distillation " might, with a little latitude, be applied to this last named stage, but it has nothing to do with the origin of either substance. While our knowledge of the formation of petroleum is still incomplete and inadequate, the following statements in regard to it are offered as embodying the most probable view: 1. Petroleum is derived from vegetable and animal substances that were deposited in or associated with the forming rocks. 2. Petroleum is not in any sense a product of...
Page 158 - ... allied products. It is the result of the primary decomposition of organic matter. 3. The organic matter still contained in the rocks can be converted into gas and oil by destructive distillation, but so far as we know, in no other way. It is not capable of furnishing any new supply of petroleum under normal conditions. 4. Petroleum is, in the main, contemporaneous with the rocks that contain it. It was formed at or about the time that these strata were deposited.
Page 18 - ... one of the most abrupt ranges of hills occurring in the drift region of the State. In the words of Dr. Dryer:* "They are as rough and irregular a pile of gravel knobs as can be found in Indiana, rising 150 to 200 feet above the lake, with a southern descent almost too steep for a horse and wagon. The range is two and a half miles long east and west, and from onehalf to three-fourths of a mile wide. It is completely isolated by the valley of the Elkhart on the east and north, and the valley of...
Page 73 - I conceive that this ridge is the superficial representation of a terminal glacial moraine that rests directly on the rock bed and is covered by a heavy sheet of Erie clay, a subsequent aqueous and ice-berg deposit.
Page 144 - In addition to the direct value of a gas-field, our alert business men have not been slow to recognize the fact that no other element, in the list of the natural advantages of a town, can be made to exert half the attractive power that the possession of a good supply of the new fuel can give.
Page 226 - Gemitz's specimen is due to some accidental cause, such a style of marking being very unusual in this genus. "In the Illinois specimens I have seen, these markings are nearly always on one side only, or more numerous and more strongly defined on one side than the other, while in other specimens differing in no other respect, I could see no traces of them. From these facts I am inclined to think they were produced by some minute parasites or boring animals, possibly on dead shells, as they were lying...
Page 142 - Indiana relating to the supervision of natural gas and the inspection of gaa wells and gas plants, I have the honor to submit to you the following detailed report of the transactions of this department for the year 1892. In this, my second annual report, I have endeavored to show to you the condition of the gas area of Indiana as to the supply of thi
Page 144 - ... the charm that invests a gas field is precisely the same as that which invests a mining district of phenomenal richness. The great advantages of natural gas are found in the support which it gives to manufacturing industries of various sorts. To certain lines of manufactures it is so happily adapted that competition, without it, is almost out of the question. Its presence invites and stimulates manufacturing enterprises to a wonderful degree. In addition to the direct value of a gas-field, our...
