Page 75 - ... rocks we find carbon under the form of graphite in gneisses (1) in pegmatite dikes, in granites, (2) gabbros, (3) and other rocks, the igneous origin of which is undeniable. "2nd. In the crystals of igneous gneisses and of most granites and other eruptive rocks, gaseous and liquid inclusions are most abundantly found, and these are very often constituted by carbonic acid and hydrocarbons, and also often contain chloride of sodium in solution or in minute crystals. "3rd. Petroleum, or semi-liquid...
Page 78 - 5th. We now come to the hydrocarbon and carbonic acid in volcanic manifestations of to-day. Not later than a few months ago the civilized world was suddenly startled and horrified at the report that an explosion of Mount Pelee had wiped away in a few minutes the entire population of St. Pierre, Martinique Island. From the...
Page 87 - ... hardly extinct yet, grouped along fractured lines and marking in that region the dying out of v/ulcanity; that is to say, the dying distant echo of that tremendous volcanic energy, which, a little farther south in Mexico, Central America and in the islands along the south coast of the Caribbean Sea, is to this day so powerfully active.
Page 91 - The oil and salt pockets of the Texas coastal plain are probably not Indigenous to the strata in which they are found, but are the resultant products of columns of hot saline waters which have ascended, under hydrostatic pressure, at points along lines of structural weakness, through thousands of feet of shale, sand and marine littoral sediments of the coast plain section, through which oil and sand are disseminated in more or less minute quantities.
Page 93 - The chief source of the supply is a lake of pitch filling the crater of an extinct volcano. This lake lies 138 feet above sea level and has an area of 114 acres. The supply is being partly renewed by a constant flow of soft pitch into the center of the lake from a subterranean source.
Page 26 - If we refer to our criminal returns, it will be found that in England and Wales, the number of persons committed for trial is now more than five times as great as it was at the beginning of the century...

Page 313 - Geography is the science which deals •with the forms of the Earth's crust, and -with the influence which these forms exercise on the distribution of other phenomena.
Page 441 - ... field has only recently been developed on a large scale, the productive measures extend from the Joggins, on the shore of the Bay of Fundy, for more than twenty miles easterly, towards the base of the Cobequid Hills. On the shore of the Bay of Fundy, the exposure is of immense thickness, estimated at 14,000 feet, extending from the Marine Limestones of the Lower Carboniferous to the top of the Coal formation. Its extent has not yet been arrived at. North- West.
Page 91 - ... they are found, but are the resultant products of columns of hot saline waters which have ascended, under hydrostatic pressure, at points along lines of structural weakness, through thousands of feet of shale, sand, and marine littoral sediments of the Coastal Plain section, through which oil and sand are disseminated in more or less minute quantities. The oil, with sulphur, may have been floated upward on these waters, and the salt and dolomite may have been crystallized from the saturated solution.
