20° east of north and west of south, and dipping 50° toward the 
east. 
On these massy strata are incumbent alternating beds of lime- 
stone and greywacke slate, some beds of the former substance 
being even four, five, and six feet thick. These rocks are much 
contorted; and indeed inflections prevail throughout the eastern 
part of this coast, from whence arise the various range and dip 
already observed. In this quarter, the deeper beds lie almost hori- 
zontally, while the superior gradually acquire the high angle 
of 50°. 
In a cove to the south, a conglomerate appears, the base of which 
is a mixture of clay slate and limestone, enveloping pebbles and 
even boulders, (two and three feet in diameter,) of limestone and of 
coarse greywacke, which consists of a clay slate base containing 
much limestone, calcareous spar, quartz, clay slate, and greywacke 
itself. 
In the southern part of this cove, the limestone is seen supporting 
massy strata of fine grained greywacke four and five feet thick, and 
forming cliffs forty and fifty feet in height ; but some of the strata 
are only a few inches, or one or two feet thick. The line of junc- 
tion is well marked by a thin seam of calcareous spar, rising from 
the south to the north under an angle of 15°. In the lower strata, 
the greywacke is a firm compact rock, of fine grain, containing 
numerous small scales of silvery mica dispersed in all directions, 
sometimes also disseminated iron pyrites, and occasionally small 
fragments of clay slate. In the upper strata, it merges into grey- 
wacke slate, and into clay slate. These slaty rocks frequently alter- 
nate with thin layers of limestone, from one inch to } or of an 
inch in thickness ; and they are also traversed by numerous small 
contemporaneous veins and strings of calcareous spar and quartz.
