The analysis of the coal collected by the writer was made
from a sample taken from the 29-inch bench in the lower part of
the seam; and, except for the low percentage of volatile matter,
resembles the analyses of the coal from Camp Robertson. In
appearance the coal is crushed and rather slaty; it is bituminous
in aspect, and in no way resembles anthracite. The low volatile
matter is ascribed to the influence of the dykes and sills of ande-
site and dacite so prevalent in the region, and a thin sill of vol-
canic rock is exposed in the adit, beyond the coal seam.

In the sandstones and shales underlying the coal seam there
are several thin streaks and seams of coal, none exceeding 4
inches in thickness. They are quite unimportant as economic
factors.

Structure. The measures are considerably disturbed in the
immediate vicinity of Camp Anthracite, and the structure has
not been worked out in detail. In the adit the measures are seen
to strike north 32 degrees west, and to dip about 85 degrees
southwest. This high dip is only local, however, and is probably
