Page 70 - Exogens, coincide with those of the Cretaceous of other parts of America, for example of Nebraska. The fossils from Hornby Island, in shales believed to overlie those of Vancouver Island, are also Cretaceous, and there is nothing to preclude their belonging to the upper part of that system . APPENDIX II.
Page 55 - Pennsylvania mines, about two thousand miles distant, and the very best of the Rocky Mountain coals are obtained directly on the line of the railroad. As a fuel for locomotives and for domestic purposes, including cooking as well as warming, the coal in general answers very well. It kindles and burns freely, making a bright fire, with a yellow blaze and comparatively little smoke ; the odor of this is not so strong or disagreeable as that of the bituminous coals, and somewhat resembles the smell...

I have the honor to be, Sir, Your obedient servant, (Signed,) JOSEPH HOWE, Secretary of State for the Provinces. ALFRED RC SELWYN, Esq., Director Geological Survey, Montreal. GOVERNMENT HOUSH, BRITISH COLUMBIA, 20th February, 1872.

This tendency to crumble is the cause of great waste at the mines — all the greater that these tertiary coals can scarcely ever be made to melt and agglutinate into a firm coke. With rare exceptions, when submitted to the coking process, they retain their form or crumble into a dry powder.
Page 13 - The facts observed lead to the conclusion, as stated by Bell, that the two series are in conformable sequence; yet it is far from improbable that this apparent conformity is only local and that a more extended and detailed investigation of the structure would show that there is in reality a very considerable break between the Laurentian gneiss and the overlying schistose and slaty strata referred to the Huronian rocks.
Page 297 - ... sinks in. The properties of the burnt bricks enumerated above, and their possible faults, are the guides for directing the selection of the clay. It is, however, nearly impossible to ascertain the applicability of any kind of clay without a direct trial. Although the mode of occurrence, the colour, the plasticity, degree of purity, property of effervescing or not with acids, may all help in enabling the brick-maker to form a correct opinion as to the nature of the clay, yet it is always advisable...
Page 195 - It seems possible that, in some cases, beds may have been formed by the accumulation of iron-sands, just as they are forming in the Gulf of St. Lawrence to-day, the material being derived from the disintegration of pre'existing crystalline rocks. Such beds we should expect to contain, not only magnetite, but ilmenite, and it is well known that in many cases, ores, on being pulverized, may be more or less completely separated into a magnetic portion, containing little or no titanic acid, and a non-magnetic...
Page 20 - ... is Lake Winnipeg, which has the same altitude above the sea level as Lake Superior, viz., 600 feet. From these lakes to the Rocky Mountains the central region may be considered as a plain gradually rising until it gains an altitude of 3,000 feet at the base of the mountain chain. The surface of this slope is marked by steppes, by which successive and decided increases of elevation are effected, accompanied by important changes in the composition of the soil, and consequently in the character...
Page 19 - These are described by Dr. Dawson (Acadian Geology, page 579) as follows: "The Cobequid range, attaining at several points a height of 1200 feet, is the highest chain of hills in Nova Scotia ; and forms in its whole length the watershed dividing the streams flowing into Northumberland Strait and Chiegnecto Bay from those flowing into Cobequid Bay and Mines Basin and Channel.
