ry’s Bay, which measures in some places 100 feet in perpen- 
ular height. It is composed of red and white sandstone, 
alternating with each other, in parallel strata, at an inclina- 
tion of very nearly 5°. It appears to have once extended 
further into the bay, as the shore is uniformly composed of 
similar sandstone, beyond low water mark. The tide rises 
here ordinarily about 25 feet ; but sometimes, when the wind 
blows powerfully in the right direction, it rises to a much 
greater height, even to 30 and 35 feet, as I was informed by 
a person residing near. When this is the case, in conse- 
quence of its dashing with such great force, the sea separates 
large masses of the stone, which are afterwards cut into con- 
venient shapes for the sides and hearths of fire places. This 
sandstone is sometimes slaty in its structure, but close in its 
texture, hard enough to strike fire with steel, and the grains 
appear to be almost uniformly of one size, occasionally inter- 
mixed with minute scales of mica, The cement is quite fer- 
ruginous and sometimes passes into red chalk, in the form of 
narrow veins or seams. 
About eight miles nearer the mouth of the bay, is a preci- 
pice of greenstone, varying in height from 60 to 70 feet, ex 
tending along the sea-shore and forming a barrier to the sea 
for a long distance. In some places it is almost perpendicu- 
far, but its general form is very irregular, as it corresponds 
im Ms course with the windings of the shore. In this preci- 
pice, I found specimens of laumonite, which were taken from 
. 
and terminating in pyramids of amethyst. In many 
places, both in vallies and on mountains, granite and cyan- 
ite (sienite ? Ed.) are scattered over the surface, in large masses, 
or apparently boulders, and often piled together in the great 
est confusion ; but I have never observed either of them in 
distinct beds, although they may eventually be found to ex- 
ist. These aggregated rocks are not therefore metalliferous, 
but T have occasione!ly noticed garnet, chlorite and schor}, 
ated through them, though not in abundance, _
