22 Dr. Mac Culloch's Account of Guernsey^ ^c. 



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 

 Jeisey.* 



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 topo- 

 graphy. 



* I have just been informed by Mr. Lowry that manganese has been lately found; but 

 i have not learnt the particulars.
