nel shaft was sunk to depth of
 ninety-fve feet on a small pocket of ore which failed to pay. A shaft
 or incline of about 45 degrees and
 eighteen feet wide by sixteen feet
 in length, was run to bring the ore from the shaft to the surface. At no point along the line of the tun- nel docs the depth of it's roof from
 the surface exceed ten feet, it was great deal of useless labor, through a valueIess mass of broken traprock held together by silicious lime states My next visit was to the Menasha claim. This claim can boast of the only legitimate mining that has been done on the company's premises. The devel- opments on this claim consist of a shaft or incline ninety-five feet deep. This incline stands at an angle of 40 degrees and Is large enough for working purposes, being 5xlO feet in the clear. At the commencement of this incline body of amygdsloidal ore was encountered about six feet
 wide and twenty feet in length along the line of stratifcation, but at the depth of 95 feet was too low grade to work. About one thousand feet easterly from the Menasha we on counter the Fon Du Lac mining claim. This claim is situated on the north bank of an arroyo and during @ recent rainstorm became filled with debris. Appearances indicate that a large body of ore exists on the flat south of this claim. To sum up, what ore there is in place on the vari- ous claims os this company, appears
 to be in segregated masses, lying
 rudely parallel with the eruptive rocks. The strike and dip of these,
 however, is found throughout the
 various explorations, as also on the
 surface, to be very irregular, and
 there is evidence in the confused
 character of the ground, as we'll as in
 the slip joints and polished surfaces of
 the rocks, that motion of the various
 beds upon one another has taken
 place along lines of limited extent and
 varying direction. The distribution of the ores in the metalliferous ground
 now under consideration, is found to
 be as irregular as is tho structure of
 the ground itself. They consist prin- cipally of the vitreous, with some variegated ores and comparatively small amonnt of copper pyrites. In general, these ores are found occur ring in punches and strings, which,
 though preserving, usually an SSp- proximate parallelism to the line of the formations, cannot be traced con- tinuously for any considerable dis tance. In general throughout the workings, tendency to a concentra- tion of the ore towards a central point may be remarked. There is central basin or flat towards which all stratas of this ore lead, no matter at
 what point of the compass it is found. The formation is trap overlying old red sandstone, where it was placed by some convulsion of nature, where it assumed the character of huge masses of broken rock carried away from the main body of ore, towards the four cardinal points of the compass, yet where the small veins occur retaining its stratl6cation. Appearances on the surface confirm me in the belief that an immense body of good ore ex- ists in the basin above referred to. All the ore stratas have a tendency in that direction at an angle of about 50 degrees. 1 am positive that no permanent veins will be found in the disturbed masses of trappean rock. the company have a 50 ton furnace erected on the premises. Its actual capacity would be about A tons. While at the furnace I examined the huxes and found that on a previous run carbonate of lime containing 45 per cent lime and fifty five per cent silica had been used, The ore being highly silicious could not of course, be smelted without the aid of high per centage of lime, less the silica, to keep the molten mass in fluid state An iron, claimed to be manganese, l found in the fuxing bin. which upon examination I found to be titanic iron. This is the worst character of iron that could be used for fuxing. It is infusible alone before the blow pipe. It is of
