Both means were a used by the forces of nature in fill " ing tke said mine with metal as can n be clearly shown.
 n By what law or natural force is il f that all materials held in solution or

 or when granulated e. left in heaps will Arrange themselves in layers, |, punches or veins, is not we'll under stood, but the fact is well established that they will do it. Build high and narrow tank" says Humboldt,
 in his Cosmic, and fill it with water l strongly iinpregnated with minerals
 quartz and other materials, held in
 solution chemically and in suspen- ] sion mechanically, and allow them
 slowly to precipitate, and let stand for time; it will be found on ex-
 animation that the different mater
 ials have arranged themselves in
 stratas lengthwise with the surface
 while the quartz and metals have
 arranged themselves in the center of
 ,he tank, mach after the form of an
 ore veiH or lode.
 'in making excavations in old piles of !ailings,' says Prof. Vim.
 Denton, State Geolog:st of Massa-
 chuse!ts, "it is found that the differ
 ent materials have arranged them
 selves in layers forming stratas, each
 of its kind"
 In these two means employed by 1
 the forces of nature the miners who 1
 helped to mangle the said mine un-
 der the management and direction l
 of 61r. Boyd, can readily compre- 1
 hend all phenomenon of the form a. tien of the ore bodies of the Copper
 opolIs mines. The ore bodies found | near the center of the dike OF claim
 No. 4. that had all the general ap- peaFance of lode, was where they had settled, while the dike was in 8 plastic state. Having separated from the rest of the dike while it was in a liquid state, while the rlch- CT side stratas, including those at the west end, were cracks and chaanbe that were filled ap by the eondens> ing of metallic gases as they entered them while working their way toA wards the surface
 Now considering the principles relative te the formation of an igs neous lode containing ore deposits or bodies, what might be expected the relative values of tke ore deposits near the surface or those deep in the lode. Evidently it would be far to suppose that the ore bod ies containing more metals and less quartz being heavier would settle faster and thus tho richer deposits of of orc would be found deep in the Z lode. Then, what woald be the most sensible way to prospect, devel- ep, and establish the value of an ie> neous lode? Most assuredly any [ good miner would say sink a shaft f from which drifts could be run at i along the line of the ore deposits that their extent and value ' night be asceTtaineG.
 New this was just what I had ;tarted in to do while conducting he preliminary prospecting I had .un a tunnel into tho hill crossing c he lode or ore deposit about 200 feet rom where it cropped out in the avine, thus demonstrating that the ode or ore body extended into the ! liil, then started a working shaft on c he top of the hill about 90 feet east f where the tunnel crossed the lode md D feet south of the cropping of :. he ore deposit. so AS to tap the de- z ,osit about two hundred feet dewn, the tunnel with the shaft t the depth of so feet and sank the haft g feet below as far as I could 70 without tirRbering, and had a !; rift run north to the ore deposit but = Ild not cut through it. r
 It will seem incrediable to any miner, but it is a fact that the Su> !: foreman Mr. Boyd :, nd tAe President of the company :; dr. Kline repudiated my work and . pronounced it worthle S. They ould have raised the water out of ny shaft and tunneled across the ire deposit in six shifst of three men ach. They sank new shaft in my unnei where the lode crossed it as leep as they could go for water, bout 46 feet, at an expense of fuil s500- They started tunnel on the ode 200 feet west level with the bot> | om of the ravins leaving no place T or vast, dump of course neither v lad they any safe place for an ore lump as the ravine was narrow and s before they were in 50 feet they were Y there waste 50 feet below f
