GEOLOGY, BY DR. BOASE.

This parish, with the exception of a narrow band of slate which skirts the coast from Pendeen Cove to Cape Cornwall, is situated entirely on granite. It has been long celebrated for its mines, which generally are placed on or near

to the junction of the granite and the slate; and in consequence of the narrow limits of the latter rock, their workings often extend under the sea. Botallack mine is a noted instance of this description; and its steam engine and machinery, perched on the side of a steep rocky cliff, present one of the most picturesque objects in the country. St. Just has afforded specimens of by far the greater number of British minerals. Its slate has a basis of compact felspar, and exhibits many interesting varieties of this rock; but the most rare is that which abounds with disseminated garnets at Botallack. The principal lodes of this parish exhibit some peculiarities in their direction, and the little coves are generally covered with beds of diluvium, some of which are composed of large granitic pebbles and boulders, which appear to have once formed a beach, although at present they are elevated above high-water mark. St. Just abounds with so many interesting objects as to make it impossible to enumerate them in these short notices. Ample details may be found of all these productions in the Transactions of the Geological Society of Cornwall.
