There are quarries established on this spot from whence stone is raised for the use of the island: it is also exported to Guernsey and to England. In times of peace it has been carried to France.
The quarries are inexhaustible; the cliffs for a long space and an elevation of an hundred feet or more, consisting entirely of this stone, in large masses apparently undisturbed by a single fissure. Shafts for columns of considerable length have been taken from the quarries, and were the demand sufficient to call for new openings, I have no doubt that columns of twenty feet and upwards might be raised.
No metallic traces, except of iron, have ever been observed in Jersey[1].
There is no trace of lime, a substance so much wanted.
The schistus, though spread wide over the island, has not hitherto afforded any slate.
I wish that my knowledge and my time had enabled me to make these notes somewhat more than a mere sketch of mineralogical topography.
