 archipelago since it was first known to whalers or settlers 

 have visited difierent districts in succession. 



The

expended each of them their chief violence in distinct areas. 



In the year 1823, there was a small cove called the Jail, 



about 80 miles north of Dusky Bay, much visited by sealers, 



for it afforded suitable anchorage for their vessels, being 



sheltered by lofty cliffs, and having deep water so close to 



the shore that they could step out of their boats on "to the

After a succession of earthquakes in 1826 and 1827, so 

 complete was the transformation of this coast that its former 

 features could no longer be recognised ; the cove had become 

 dry land, and trees were seen under water near the coast, 

 having probably been carried down by landslips into what

my work. The late Von HofF published which accoimts were published since 



from time to time, in Poggendorf s An- that time by Prof. Alexis Perrey, of 



nalen, lists of earthquakes which hap- Dijon. A continued series of accounts 



pened between 1821 and 1836 ; and, by of earthquakes and volcanic eruptions 



consulting these, the reader will perceive by the last-mention(>d author, drawn up 



that every month is signalised by one with great care, since 1842, has been
