Side 565 - land known at the time to be valuable for its minerals," as there are vast tracts of public land in which minerals of different kinds are found, but not in such quantity as to justify expenditures in the effort to extract them. It is not to such lands that the term " mineral " in the sense of the statute is applicable.
Side 565 - ... rich deposits of mineral may be discovered. It is quite possible that lands settled upon as suitable only for agricultural purposes, entered by the settler, and patented by the government, under the preemption laws, may be found, years after the patent has been issued, to contain valuable minerals. Indeed, this has often happened. We therefore use the term known to be valuable at the time of sale to prevent any doubt being cast upon titles to lands afterwards found to be different in their mineral...
Side 565 - We also say lands known at the time of their sale to be thus valuable, in order to avoid any possible conclusion against the validity of titles which may be issued for other kinds of land in which years afterwards rich deposits of mineral may be discovered. It is quite possible that lands settled upon as suitable only for agricultural purposes, entered by the settler, and patented by the government, under the preemption laws, may be...
Side 565 - States to land known at the time of sale to be valuable for its minerals of gold, silver, cinnabar or copper could be obtained under the Preemption or Homestead Laws, or the TownSite Laws, or in any other way than as prescribed by the laws specially authorizing the sale of such lands — except in certain States, not affecting the question before us, commenting particularly upon the terms "known...
Side 540 - Fall. of prehnite, associated with calcareous spar, and native copper. The Indians dig wherever they observe the prehnite lying on the soil, experience having taught them that the largest pieces of copper are found associated with it. We did not observe the vein in its original repository, nor does it appear that the Indians have found it, but judging from the specimens just mentioned, it most probably traverses felspathose trap. We also picked up some fragments of a greenish-grey coloured rock,...

Side 119 - There are 44 tuyeres, 1*4 in- in diameter and 7 in. apart. There are no tuyeres directly under the stack. The length inside the lining is 33 ft. 3 in. The bottom is 2 ft. thick, the back or tuyere wall is 18 inches and the front 15 inches thick. The roof is a 12-inch arch. The brick directly around the tuyeres is 24 inches thick.
Side 536 - The Indians who were the occasion of my undertaking this journey, represented this mine to be so rich and valuable, that if a factory were built at the river, a ship might be ballasted with the ore, instead of stone ; and that with the same ease and dispatch as is done with stones at Churchill River. By their account the hills were entirely composed of that metal, all in handy lumps, like a heap of pebbles.
Side 528 - He had two northern Indians with him who had wintered at Churchill, and told him of a rich copper mine somewhere in that country, upon the shore near the surface of the earth, and they could direct the sloop so near it as to lay her side to it, and be soon loaded...
Side 535 - Mr. Norton has proposed an inland Journey, far to the North of Churchill, to promote an extension of our trade, as well as for the discovery of a North West Passage, Copper Mines, &c.; and as an undertaking of this nature requires the attention of a person capable of taking an observation for determining the longitude and latitude, and also distances, and the course of rivers and their depths...
