about 20 feet high. The north, 5-foot vein continues to this point along the
floor of the cut and extends upwards for 12 feet on the end rock face, but
there abruptly ends and is sueceeded upwards by a zone of much fractured
rock. The south vein at the west end of the cut lies about 15 feet south
of the north vein. Beyond the end of the cut the south vein is exposed in
two places with widths of 3 to 4 feet and at a third place 290 feet west of
the end of the cut it varies from 2 feet to an inch or so in width. Two
hundred feet farther along the strike there are indications (vein No. 8 A) of
a possible continuation of this vein.

The information gained along the open-cut and in the tunnel indi-
cates, that as confirmed by imperfect evidence from other sources (a) the
veins are very steeply inclined to the north, but are subject to local variations
in the angle of dip and strike; (b) the veins fork and may end abruptly;
and (c) much of the wider parts of the veins is very rich in apatite.

Vein No. 9. Vein No. 9 lies west of No. 8 vein, but not in line with it.
No. 9 vein as indicated by a few outcrops is a single vein for a length of 140
feet, beyond which it splits into two diverging veins each traceable west-
ward for a length of nearly 300 feet. The easternmost outcrop where the
vein appears as a single body is 5 feet broad and presumably the vein
continues eastward some considerable distance. A short distance south
are exposed one or more thin veins presumably paralleling No. 9 vein, but
not exposed elsewhere. At its next outcrop to the west, No. 9 vein is
15 feet wide and forks nto two narrow diverging branches. The southern
one outcrops for a length of 200 feet with a width at the end of the exposures
of 33 feet. Thirty-five feet northerly is exposed the northern of the pair
of branching veins and it is at least 5 feet wide. These two veins are not
known to outcrop any farther westward and presumably rapidly die out
in that direction.

Vein No. 10. Vein No. 10 lies north of veins Nos. 8 and 9 and is
situated on the edge of a broad, exposureless area extending down and
along the face of the hill. The vein is exposed at only one place and there
has a width of 20 feet and a length of 50 fect, but only one-half the exposure
is of pure magnetite, the remainder being largely apatite and fragments
of rock. One hundred feet south of No. 10 vein, another vein, 2 feet
wide, is exposed over a length of 10 feet.

Vein No. 11. Vein No. 11 is exposed at intervals over a length of
150 feet. It has a width of 2 feet. Fifty feet south of it is one exposure
of a vein of about the same width.

Vein No. 12. Northward from the entrance to the tunnel on No. 8
vein, a number of exposures of narrow veins occur in a distance of 450
feet measured across their strike. The veins are not traceable for more
than a few feet. The most southerly of these veins is exposed at intervals
over a length of 60 feet, in places is 3 feet wide, but is not continuous along
thestrike. About 15 feet north of this vein is a single outcrop of a narrower,
parallel vein. One hundred feet north, a one-foot vein outcrops at inter-
vals over a length of 50 feet. One hundred feet farther north are three
exposures of magnetite. One of these is a 2-foot vein dipping at a com-
paratively low angle; the second is a body 5 to 10 feet in diameter; and
the third is of a vein several feet wide. One hundred and fifty feet farther
north is a group of four exposures at each of which occur one or two veins
a few inches or a foot wide.
