GEOLOGICAL OBSERVATIONS 



On September 8 a single jet of steam shot up to an 

 immense height, apparently to about twice the height of 

 Mount Erebus. A strong gale was blowing at the time, 

 and the steam was carried away in a few seconds, so that 

 there was no time to take an angle. In spite of the gale 

 the steam shot up with such velocity that the column 

 appeared quite vertical. The figure shows it too near 

 Erebus, for the sake of comparison.
