22 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.

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.
