TORNADOES. 169 



Sandy Hook, on December 24, 1853. In a few 

 moments she was a complete wreck ! The wide range

THE eruption in progress, as we write, from Mount 

 Vesuvius, and the numerous and violent eruptions 

 from this mountain during the two last centuries, seem 

 to afford an answer to those who think there are traces 

 of a gradually diminishing activity in the earth's inter- 

 nal forces. That such a diminution is taking place, we 

 may admit ; but that its rate of progress is perceptible 

 that we can point to a time within the historical 

 epoch, nay even within the limits of geological evi- 

 dence, at which the earth's internal forces were certainly 

 more active than they are at the present time may, 

 we think, be denied absolutely. 



When the science of geology was but. young, and 

 its professors sought to compress within a few years 

 (at the outside) a series of events which (we now 

 know) must have occupied many centuries, there was 

 room, indeed, for the supposition that modern volcanic 

 eruptions, as compared with ancient outbursts, are but 

 as the efforts of children compared with the work of 

 giants. And accordingly, we find a distinguished
