twenty-five ounces; fifteen tons, one hundred and nineteen 
ounces ; and twelve tons, ninety-five ounces. The lead varied 
from twenty to seventy per cent. During 1890 considerable 
more was shipped. 
The deepest mine in the camp is only one hundred and thirty- 
two feet deep, and, as all the ore has to be packed down at pre- 
sent, and the expenses of getting to smelters in the absence of 
railway transportation are so great, it is being piled up at the 
mines, awaiting further development. 
Ascending the mountain, I first examined the ‘Jeff Davis” 
claim, which is about seven hundred feet above the level of the 
lake. The vein is quite well defined, showing eighteen inches 
of ore in mica schist. The pure galena carries about twenty 
ounces of silver to the ton. ‘This vein is in the first lode from 
the lake, at a height of about eleven hundred feet above it. In 
the second lode is the ‘‘ Spokane,” showing a twenty-six inch 
vein of galena in mica schist, the pure galena carrying about 
forty ounces of silver to the ton. The gangue is quartz, and 
a considerable amount of iron pyrites is visible, but only a few 
feet of shaft have been sunk on the vein. On this same lode 
are several extensions more or less developed. Following up this 
trail, I next came to the ‘‘ Sunlight,” at an elevation of nine- 
teen hundred feet, and in the third of the main lodes. This 
is in the limestone, and shows considerable development, the 
ore being more or less oxidized, the mineral body being twenty 
inches in diameter, uncovered fur some distance, and the clear 
galena assaying sixty ounces of silver. 
There are several more claims on this lode, with more or less 
development. In the fourth lode I next looked at the ‘‘ No. 
1,” at an elevation of twenty-five hundred feet above the lake. 
Considerable work has been done. The ore body is large, se- 
lected samples showing one hundred and fifty-seven ounces of 
silver totheton. ‘The mineral, partly carbonate, partly galena, 
occurs in grayish limestone and is uncovered for several hun- 
dred feet. The ore is very friable and decomposed at the sur- 
face, but sulphurets and wire silver are found at depth. 
There are a number of other locations on this lode, but I did 
not visit them. The highest claim is the ‘“‘Sky Line,” situated 
southwest of, and over a mile from, the last, at an elevation of 
nearly five thousand three hundred feet above sea level. It is 
being actively and liberally developed, the vein being fourteen 
feet wide and the ore showing considerable wire silver. Near 
the surface it is very much altered and decomposed, but at 
depth considerable galena is obtained. This ore is being packed 
to the lake, and shipments of several carloads of selected ma- 
terial have yielded three hundred ounces of silver.
