being the rule rather than the exception. Numerous dykes and sills of
granodiorite and porphyritic granodiorite intrude the sediments.

A 8-foot coal seam is exposed on the western bank of Kispiox River
54 miles above the junction. This seam occurs on the north limb of a
faulted anticline. On the eastern bank of the Kispiox about 4 mile farther
upstream another coal seam, with a maximum width of 3 feet, is exposed.
The coal in both seams is very impure and crushed. Local inhabitants
have used coal from these seams in their forges.

Three, small, dirty, and crushed coal seams were observed along the
west bank of Skeena River between Kispiox village and a point approxi-
mately 5 miles north. At this point two seams are exposed. Normally
they are 6 to 12 inches wide, but due to faulting and folding they form
pockets that are much wider. In an open-cut 15 feet above the river,
one seam has been squeezed at its junction with a fault so that now the
coal forms a pocket 4 feet in width and 20 feet in length along the fault
plane. In a second pit, 50 feet higher, the second seam is exposed. It has
migrated under pressure to the crest of a small anticline where it forms a
body 20 feet long, 10 feet wide, and at least 6 feet thick. The local
inhabitants use the coal from these two seams in their forges. A repre-
sentative sample of coal collected from the pit 15 feet above the river and
analysed by the Fuel Testing Laboratories at Ottawa, gave the following

analysis:

Seven miles above me junction of tei sree Kispiox Rivers, on
the west bank of the Skeena, a slide has laid bare a face of rock 300 "feet
high. The sedimentary section exposed on this face is broken by a fault.
The thickness of the section below the fault is approximately 400 feet
and above approximately 600 feet. The lower 400 feet of the series .
contains three coal seams, 1-9, 0-6, and 1-3 feet thick, respectively, and the
upper 600 feet of the series contains four seams 1-4, 0-9, 0-6, and 1-3 feet
thick, respectively. According to Malloch?, three samples of coal from these
seams gave the following analyses:
