Mr. STEWART. Here are parallel veins, pitching, say, at an angle of 45 degrees, one after another. If you sell in square sections with perpendicular lines extending into the earth, any quantity you please, one man may have a piece of half a dozen veins and yet have no vein to work. To open a silver vein costs all the way from 50,000 to several million dollars, and to work it requires long tunneling, and it requires a system of tim ering from the top. If a man has only a short piece, and is required to go into the earth by perpendicular lines, he might cut through several veins, but no system of working could be adopted. The veins are separated by rock walls, so that there is no possibility of confusion. You give a man a vein, or so man feet running with the vein and following it own. Suppose, for instance, you give a man 3,000 feet. It dips 45 degrees. If you were to undertake to give him that byyour present system of selling the land by perpendicular lines, what would be the result? In order to work that vein he must have a large quantity of ground. It is supposed that the veins ordinarily have been worked down 3,000 feet. Then you would have to give him an extent of 3,000 feet latera ly. In these 3,000 feet there might be 20 or 30 other veins; so that under that svstem, in order to give him one vein you woul. have to give him a comlcte monopoly of a whole district, or you won d give it to him in a sim e that he could not do anythin. The practica necessity of the case requires that the ips of the veins shall be followed. A vein is an expensive thing to work, and any other sys tem of sale would destroy the whole country; and that is the principal reason why the miners have been objecting to sales, because the perpendicular lines would out 11 their claims and no man would purchase. I you undertake to divide the lands in the minin country by have in the lines extend perpen icularly, mining wi I be effectually at an end. That is the reason why the people there have been excited and alarmed Iby rojects for the sale of the mining lands is bill, however, has been out there, has been submitted to the people, and meets with universal a probation. We so understand from letters an byevery newspaper we receive, and there are many mining jour nalsin California and Nevada, and eve one of them has indorsed it, because it allowst e miners to work the mines. There has been a misunderstandin" between them and persons here in regard to towhole matter, they supposing that we here intended to divide the country in such a manner that they could not work the mines. The bills introduced had been of that character, and that is what created the excite ment. I will say further, that the introduction of those bills has depreciated the whole mining country, and has undoubtedly prevented the production of 50 millions of money, because no man would invest his money in opening a silver mine with a prospect of having it cut at right angles after be ad spent several 100,000 dollars in opening it.
