Thompson Falls CLAW.

Within half a mile of Thompson Falls,
on the road to Ceur d'Alene, near the
junction OF Ch,rry and Prospect creeks, is
a deposit of a very superior article oil fire
clay. The deposit is in blanket form and
covers an AREA Of something over fifty
acres of ground. 1t lies in three separate
or district stratas or veins.
The first or upper strata is about three
and a half feet thick and contains about
30 per cent. aluninum and about 60 per
cent. silica. The second vein is about four
feet thick and carries 66.7 to 81 OF silica
and 10 to ~ OF aluminium. The third vein
is from 8 to 10 feet thick and is from sc To
81 per cent. OF silica and from 10 to 70
per cent. aluminium, thus making g vein of
from ID to I6 feet in depth. this being as
lar down as the parties have been abls to
go i'll consequence of water. The farther
down tn y go the richer it gets in silica.
IL Is estimated that with proper machinery
Tor dlsposing OF the water the vein of CLAW
will run down from 25 to 80 feet and per.
haps deeper, as they have never yet been
able to find the bottom.
Ih,s clay has been analysed by Carney e.
Hand and Stechi OF this CITY: by Mr.
Bridge and other assayers of the Ana.
conda; br Mr.. Seville of the Boston g. Mon.
tana; by Grant & Pr, ston OF New York.
and by Prof. Tingley of Boston, and the
assays OF these gentlemen give the results
o stated; and in no instance where
anais eng from the same strata have they
differed more than l or X per cent, The
entire absence OF alkali and other burifnI
components Is most marked in the ASSAYS
which have been made OF this Cay, there !
not being even a trace Of alkali discovered !
