the vein, and ;seems to be the general character of fhe deposits-for a
distance of fifty Peet in depth, or down to the pinch in the vein.
Another product is found in pockets or smalls in the vein, which seems
' to have been a secondary flow, muoh darker in appearance,very brittle
with conchoidal fracture, granular structure with brownish powder and
appears to be a similar product to the'uintaite or gilsonite of :the
Utah fields. This too is wanting in volatile matter, easily fusable
uhder flame, but will not melt of itself. Is soluable in oil, but at
~- 300 deg. Far. This would appear to be the character of the product
\4 below, though it is believed it will become more solulble without
excessive heat, and contain more volatile matter as depth is gained.
The basin to the east of these deposits and in the country west
of @rand Lake, in many places shows an overflow of Brea,~but its source
has not been found.
The deposits so far discovered are almost inacceasable, owing to
the distance, 60 miles, from the nearest railroad point. Cost of
transportation by wagon to railroad is necessarily great, owing to the
rough mountain roads and high passes to bo crossed. The deposits
' can only be worked during the summer months, if the produ;t is found
to be of aufficlAnt value to work at all.
.About 200 tons of the product was taken out~in 1898. A portion of
the second grade described above was marketed at $30. Tho cost of
wagon haul, $18. Railroad freight $12.50. oost of mining and Hacking
$1G. per ton.
Itis doubtful whether the product cnn bo made available for the
narkot in whatever bracoh of the trade it might be used, until
cheaper mean:i for transporhation can be afforded.
