in considerable demand. Regarding the question whether there 
sufficient high-grade silver ore or stibnite to pay for working, no! hi 
definite can be said. It is probable that both the lead and antimoii 
sulphides and the small amount of iron pyrites associated with the 
occur as small veins scattered through the schists. Although bo 
stibnite and galena resemble each other to some extent, the form 
has often been determined by miners through its character of fusil 
readily in the candle flame. The coarser varieties can also be d 
tinguished from galena by their lighter color and somewhat fibrq 
texture. The coarser varieties of galena break into little cubes. 
There is a great resemblance between the Kantishna and Fairban 
regions. The geologic environment and mineral associations a 
practically the same. The essential difference is apparently one 
physiographic development. The Kantishna region is in a youth 
stage. The valleys are narrow and have steep grades, and tin 
deposits are consequently shallow and have undergone less shifts 
with the accompanying gravitative differentiation of the heavy cd 
stituents to the vicinity of bed rock. 
The hulk of the production has come from Eureka Creek and mc 
of the remainder from Glacier Creek. The conditions on Eure 
Creek probably find an explanation in the fact that the heavy forei: 
wash derived from the bench near the mouth, working in combinatii 
with a decrease in grade, checked to a greateror less extent the renurv 
of the gold that was being brought down the valley of Eureka (Ye 
while the canyon was being cut, and thus brought about an enric 
ment at this particular point. There is the possibility, too, that t 
bench gravels contributed a part of the gold. It is noteworthy 
this connection that the richest ground on Glacier Creek is at t 
point where the valley emerges from the hills into the benched ar 
that surrounds their base. 
There was no lack of water during the summer of 1906, but in 
tlvy season the small creeks would shrink below the economic lira 
The timber resources in the vicinity of the hills are scanty. The 
is some fair timber along parts of the valley of Moose Creek and tl 
increases in quantity toward the mouth, hut in general the localiti 
where mining is done are above the limits of good timber, and hind; 
has to be packed for several miles. The town sites of Glacier ai 
Diamond were well timbered, and the valleys of the Bearpaw ai 
Kantishna contain many small areas of fine spruce. 
Steamer transportation during the summer of 1906 was ve 
irregular, and the accessibility of the placers to the points where it 
possible to land supplies from steamers is rendered difficult on accou 
of swampy areas that in places well-nigh block the approaches tot 
hills. Up to the present time but little -attempt has been ma
