Just above the mine which had been worked at Trewavas 

 Head,"" and about 300 or 400 yards from the barrow, are two 

 granite blocks with artificially formed basins. 



One of these stones measures 4 feet 3| inches in length, 1 foot

 by 1 foot 9 inches in width, and 5| inches deep ; is of the same 

 form as the first, but occupies a more central position in the stone. 

 Some portion of this latter block has been broken away by boring 

 with a metal tool in modern times ; and holes for a like purpose 

 had been commenced in the other ; but these efforts in the art of 

 rock-splitting I beheve to be much more recent than the formation 

 of the basins. 



Eesidents near the spot can give no account of these stones ; 

 miners refuse to acknowledge them as utensils required in their

 of the Transactions of the Geological Society of Cormvall. The cliffs and 

 other objects between Perran-Uthnoe and Porthleven — a portion of the 

 Cornish coast not much visited — are well worthy of the attention of tourists.
