It contains, where seen by Mr. Palache, rather abundant 
inclusions or segregations, which are dark in color, banded 
or schistose, and porphyritic with quartz and feldspar crys¬ 
tals. It is cut by dikes of pegmatite and aplite. In one 
case the aplite is cut by pegmatite (fig. 1), in another the 
pegmatite is cut by aplite (fig. 2). The aplite (12), in addi¬ 
tion to quartz, orthoclase, and a little plagioclase feldspar, 
contains minute garnets and isolated octahedra of magne¬ 
tite. Veins of alteration containing epidote were noted. 
These granitoid rocks continued on north through Gren¬ 
ville Channel and Chatham Sound. At the deserted In¬ 
dian village on Cape Fox, west of Duke Island, we found 
monotonous old-looking gneisses, quartzites, and coarse 
hornblende- and mica-schists, much tilted. 
Just across the straits at the Indian village of New 
Metlakatla, on Annette Island, we made the following 
section along the coast from the town west to the cliffs 
and cascade: 
1. Highly inclined schistose rocks, often chloritic, with frequent in- 
terbedded bands of what appeared to be highly altered sandstone. 
2. A considerable thickness of a much veined and jointed green¬ 
stone, probably an altered intrusive. 
3. The cliff near the Cascade and probably the whole neighboring 
mountain is of yellowish arkose, much brecciated, and veined with 
flint.
