Σελίδα 178 - The thing that hath been, it is that which shall be; and that which is done is that which shall be done: and there is no new thing under the sun. Is there anything whereof it may be said, "See, this is new"? it hath been already of old time, which was before us.
Σελίδα 160 - Report in 1904 to the Minister of the Colonies on the Mineral Wealth of New Caledonia" the foregoing is taken, states that New Caledonia has practically a monopoly of the production of cobalt in the whole world. He further says that while the deposits of the mineral are capricious they are at the same time numerous and extended. This monopoly has now been broken by the discovery of the Ontario deposits. At the time of Mr. Glasser's visit to the colony, the prices paid for cobalt ore were about as...
Σελίδα 54 - In the present state of our knowledge we have little warrant for claiming that the granite boulders, often two or three feet or more in diameter and distant a couple of miles from exposures of the rock, indicate glacial conditions during Lower Huronian times, although we have no proof to the contrary.
Σελίδα 53 - It is difficult to understand, for example, how certain large boulders of granite in the conglomerate, which forms part of the highest outcrops of the Lower Huronian, have been carried so far from their parent masses. These large boulders are found over much of the district, and there are now no outcrops of granite in the neighbourhood of many of them.
Σελίδα 153 - ... location on lake Superior. In this locality it is associated with vitreous copper, green and blue malachite and native silver, while other parts of the same vein yield native silver, vitreous silver, blende and copper pyrites; in this connection it may be mentioned that a mass of silver ore selected by myself from some hundreds of pounds, as an average sample, gave on assay 3.6014 per cent, of silver, equal to 72 lbs.
Σελίδα 36 - JS 14, near the foot of Cobalt lake, the slate is seen to be practically horizontal. The vein here referred to is at the base of a cliff, which rises to a height similar to that of the hills across the railway track to the westward on the southern part of RL 400. In the former case, the hill is composed entirely of the...
Σελίδα 6 - There are probably some other closely related arsenides of cobalt in addition to smaltite in this ore. The diarsenide of nickel, chloanthite, is also present. At times some massive tetrahedrite is seen, and it is usually associated with copper pyrites, which helps one to identify it. It is, however, usually readily recognizable by its black color and bright appearance. Much of the surface of this ore shows the decomposition product, cobalt bloom, the arsenide having been changed by atmospheric agencies...
Σελίδα 32 - ... runs for 12 or 14 miles, parallel with the second great system of water courses, to Haileybury on Lake Temiskaming. The direction followed by the railway for the first 90 miles of its course proves that there is a line of depression here, parallel with the Ottawa river and Lake Temiskaming although it is not indicated by water courses on the map along the greater part of the route. Continuing northwestward from Wabi bay, the northwest corner of Lake Temiskaming, and in line with the direction...
Σελίδα 8 - In evaporating the solution of the metals I had a very interesting result. The solution was quite concentrated, and on cooling, green acicular crystals of the nickel compound separated out, while the solution above and around them was quite pink. The original solution before the crystallizing out of the nickel compound was quite blue.
Σελίδα 11 - ... smaltite, the theoretical percentage of arsenic in the ore should be 68.47, instead of 69, as found by analysis. The percentage of niccolite by w'eight would be 15.94, or about one-seventh part of the whole by volume, since niccolite has a somewhat higher specific gravity than smaltite.
