42 THE GEYSERS OF PLUTON RIVER, 
noise beneath the earth’s surface, quite equal to and 
resembling that made by several ocean steamers, letting 
off their steam through their large pipes, loud, deep, 
and harsh. There was no cessation to this awful roar, 
but one continued noise, as though a vast workshop 
‘beneath was in full operation. 
The banks of the gorge were now too steep t0
