Stran 389 - ... to file in the local Land Office a diagram of the same, so extended, laterally or otherwise, as to conform to the local laws, customs, and rules of miners, and to enter such tract and receive a patent therefor, granting such mine, together with the right to follow such vein or lode, with its dips, angles, and variations, to any depth, although it may enter the land adjoining, which land adjoining shall be sold subject to this condition.
Stran xxiii - All vacancies shall be filled by the appointment of the Council, and any person so appointed shall hold office for the...

Stran 116 - None of the ingredients, except carbon, in the proportions present, seem to very notably aflect welding by ordinary methods. II.

Stran 116 - Phosphorus up to 0.10 per cent does not harm, and probably improves, irons containing silicon not above 0.15, and carbon not above 0.03. None of the ingredients except carbon in the proportions present seem to very notably affect welding by ordinary methods.
