Different Etcropcan Chains of Mouniains. 305 



island, near Santorino, in the Greek Archipelago, in 1707, seem 

 to be also calculated to prove that the subterranean fires not 

 only contribute to raise the mountains by means of ejections 

 furnished by the craters of volcanoes, but that they also some- 

 times raise the already consolidated crust of the globe. The 

 extract which I here present of accounts published at the time 

 by Bourguignon and Father Goree, both witnesses of the event, 

 seems to me liable to no objection. On the 18th and 22d of 

 ]May 1707, slight shocks of an earthquake were felt at Santorino. 

 On the 23d at sunrise, there was observed, between the large 

 and the small Kajncni (two islets), an object which was taken 

 for the hull of a wreck. Some sailors went to the place, and on 

 returning reported, to the great surprise of the whole popula- 

 tion, that a rock had risen from the waves. In this region, the 

 sea had previously been from 80 to 100 fathoms deep. On the 

 24th, many persons visited the new island, landed upon it, and 

 gathered upon its surface large oysters, which still adhered, 

 to the rock. The island was actually seen rising. From the 

 23d May to the li3th or 14th June, the island gradually in- 

 creased in extent and elevation, without noise or shocks. On 

 the 13th June, it might be half a mile in circumference, and 

 from seven to eight yards high. No flame or smoke had yet 

 issued from it. From the moment when the island appeared, 

 the water had been troubled near its shores ; and on the 15th 

 June it became almost boiling. On the 16th, seventeen or 

 eighteen black rocks issued from the sea, between the new island 

 and the little Kameni. On the 17th, they increased consider- 

 ably in height. On the 18th, smoke rose, and great subter- 

 ranean noises were for the first time heard. On the 19th, all 

 the black rocks were joined together, and formed a continuous 

 island, totally separate from the first. Flames, columns of 

 ashes, and red-hot stones issued from it. These volcanic phe- 

 nomena were still going on on the 23d May 1708. The Black 

 Isle, a year after its appearance, was five miles in circumference, 

 one mile broad, and more. than 60 yards high. 



It is evidently seen, in this account, that the appearance and 

 enlargement of the first island were not accompanied with any 

 volcanic phenomenon, and that it could not be considered as a 

 product of ejected matter. Now, this is the very idea at which
