A New Island.—A Tacoma, Wash., despatch of the 8th inst., gives this interesting bit of news:
Amid waves which are still boiling from the heat of a violent submarine eruption, a new island lifts its rocky head above the sea near Boroslov island, Alaska, which was thrown up by a similar eruption about 100 years ago. The infant island presents a superficial area of several acres, and with Boroslov, and other small islands which rose from submarine depths in 1882, forms points of the small triangle about seventy miles west of Unalaska. News was brought to Unalaska by fishermen, who were unable to approach the island because the water surrounding it was still seething from heat, indicating that its upheaval was of recent occurrence. When observers attempted to approach closely, they found the water so hot that they were compelled to keep away. Several little volcanoes exist in the broken chain of land and geological formation of the later ages, largely cetaceous and miocene. The region contains numerous dikes of plutonic rock and many boiling springs.
