Dear Sir :—I add a line to the above to inform you that up to this 
date the action of the late eruption is undiminished. ‘Truly our island 
's on fire. A line from Mr. Coan informs me that he passed within 
five or six miles of a stream of lava, yesterday, which was burning its 
path through the woods, in the direction of Puna. ‘The action on the 
mountains was more intense last night than it has been since the morn-

knowing when, and where, and how, this fiery flood is to reach the sea. 
The locality of its source almost precludes the hope that its progress 
can be as harmless as on a former occasion

of lava had burned through the woods to within fifteen miles of Hilo, 
and that it was still progressing. The cur

it was supposed at that date, that it would ultimately reach the sea, and 
discharge itself into the bay of Hilo. 
_ The light at night was very brilliant, and at Hilo it was almost as 
light as day, Persons who left this city last week on a visit to Hilo, 
will arrive ata seasonable moment to witness one of the most sublime 
Phenomena. of nature, and ‘one of so rare occurrence that few are for- 
tunate enough to witness it.—Alta California. 
[According to later accounts the eruption ceased when the stream 
had reached within seven miles of Hilo.
