of a kind of pumice, which is so hard as to form millstones, 

 but of a very bad sort, and the chief cause of the bad bread 

 which is eat in all the Archipelago. 



Of Paros, though celebrated for its marble, the high hills 

 are of granite -, but clay-slate also appears in the vicinity of 

 the marble. 



Miconi is chiefly of granite and basalt. There are currents 

 of volcanic glass, from one to fourteen inches in breadth, in 

 the granite, which is also interspersed with basalt. Towards 

 the south a crater appears full of volcanic glass, basalt, and 

 many kinds of stone which have evidently undergone the 

 action of fire. Towards the port is decayed granite, and there 

 is no mark of limestone. 



Scio is one of the most beautiful of the Greek isles, and 

 the people the most amiable and intelligent. In the torrents 

 are found many kinds of granite, jasper, agate, carnelian, 

 quartz, and calcareous spar. There are also ancient mines 

 of silver; and some volcanic appearances. Scio is famous 

 for the culture of mastic ; and the population is computed at 

 sixty thousand. 



The hills of Mitilene are sometimes wholly composed of 

 pure and white pumice, while others are granitic, and the 

 greater part calcareous. The mountain called Kara is wholly 

 composed of fragments of basalt, quartz, and a black stone 

 which seems a trap of the Germans united by a cement which 

 is half calcined. 



Near Smyrna the highest mountains are of granite. One 

 hill appears split in two halves ; of which one, which is sepa- 

 rated to the distance of about 300 paces, is all broken in 

 pieces. The internal fissures of the mountain are filled with 

 a white limestone, like the marble of Paros, which penetrates 

 the granite in every direction, in veins from one inch to 130 

 paces in breadth. Here, and at Paros, the marble is sepa- 

 rated from the granite by a layer of green mica-slate. The 

 calcareous hills about Smyrna may often be distinguished 

 from the granitic by being cavernous, and yielding a hollow 

 sound under the feet. Bournabat, the fairest part of the
