Granite.

The Granite quarry comprises the high level, at a height of about 120 feet above the sea level, and the long ranged low level quarries extending for nearly a mile along the beach, to which the railway from the high level descends at a gradient of 1 in 40. The low le- page 3 vel quarries, which originally showed a grand face of rock, have proved most disappointing and unsatisfactory, from the great amount of soft disintegrated stone which had to be stripped and removed to get at the hard and sound patches. It is therefore fortunate that the breakwaters are just about completed when these quarries show signs of exhaustion. There is still some stone to be got from them, but the quantity and quality is now uncertain.
