In accordance with the geological law that regions of the greatest 
disturbance are generally those of the greatest metamorphism, it 
is not strange that the rocks of the West Passage are more meta- 
morphic than those of other portions of this section of the basin. 
On the west shore of the Island of Conanicut the Coal-measures 
dip E.S.E. true, away from the west side of the basin, the nearest 
rocks to the west being the Mica-schist (B), which forms there 
the shore of the mainland. In examining the outcrops on the 
west shore of the northern portion of Conanicut, which, with oc¬ 
casional interruptions, extend some three miles or more, I noted 
the following section, beginning with the more recent strata : 
Mica-schist with Garnets, Staurolite, Ottrelite and Chlorite, 4 
feet. 
Plumbaginous Argillyte, with minute veins of Mica and coal 
ferns, 3 feet. 
Mica-schist with Garnets, Staurolite, Ottrelite and Chlorite (in¬ 
cluding 2 feet of Plumbaginous-schist), 10 feet. 
Several layers covered, but conformable. 
Mica-schist with Garnets and Chlorite (including a few inches 
of Plumbaginous Argillyte), 3J- feet. 
Quartzose Mica-schist (including 2 feet of Quartzyte with radi¬ 
ate Asbestus), 7 feet. 
Plumbaginous Argillyte with Garnets and Chlorite, 2 feet. 
Mica-schist with Garnets, Staurolite, Ottrelite and Chlorite, 8 
feet. 
The Staurolites occur as single crystals, twins of 6o°, and drill¬ 
ings. The Garnets and Staurolites are generally partial pseudo- 
morphs of Chlorite after Garnet or Staurolite. 
If such highly crystalline Paleozoic rocks occur in one region 
they may elsewhere ; and it would not be surprising if some met- 
amorphic rocks, now regarded as of Azoic or Eozoic age, should 
be ultimately found to belong to the Paleozoic.
