that was practically free from corundum and 
ore. This mine was worked 
very extensively over twent}^ 
years ago, but had been aban- 
doned until 1899, when it 
was reopened. The old works 
were near the highest point of 
the vein, on the slope of the 
mountain, and were worked 
for about 30 feet. The new 
work was started 1 1 7 feet be- 
low the mine, and a tunnel 
from the east side was run 1 1 1 
feet to the vein. When this 
was reached a shaft and tun- 
nels were started. At this mine 
the corundum occurs in whal 
might be called porphyritic 
crystals of a bronze color, 
which are from 5 to 15 mm. 
across. Here blue and while 
masses of corundum weighing 
several pounds have been 
found, and small, well-formed 
blue crystals are also frequent . 
A little north of this mine, in 
an old opening, a cross vein 
of chlorite was encountered 
which carried a great many 
almost perfect cubes of pyrite 
and radiating groups of black 
tourmaline. 
The last opening on the vein 
where there has been any work 
isat the Snow mine, over a mile 
north of the Sackett mine. A 
small open cut was made that 
exposed the vein, 3 feet in 
width. Between these two 
mines and also from the Snow 
mine north to the river the 
vein can be followed almost 
continuously. 
While the vein can be fol- 
lowed nearly the whole dis- 
tance, the emery does not occur throughout iis

entire length, for it is
