3. Eruption of Hina.—A letter by Mr. Fouqué in “Les Mondes” of the 
6th of April, contains the following: At half past 10, on the evening 
of the 21st of January, there was a severe earthquake, and immediately 
after, the eruption commenced. It broke out on the northeast side of 
the mountain at a point about 1700 meters above the sea-level and 500 
our lower craters detonated differently from the three others. The

“The submerging and uprising of the island in the boiling cauldron of 
the crater, is a rare and grand spectacle. The henomenon occur-

red in June last, with this difference, that the island disappeared entirely 
for several days, but was gradually restored by the spouting liquid lava. 
“I was at Kilauea on the 9th and 10th inst. There was much action 
lands, some fifteen miles from Kilauea, I passed many large pit and cone 
craters, most of them ancient and densely wooded, from 300 to 800 feet 
in height and depth. Ispent a night near a beautiful pit-crater called 
Napau, nearly circular, about 300 feet deep, a mile, perhaps, in diame- 
ter, and with a bottom of sand, so smooth and hard that a regiment of 
cavalry might be reviewed there, One-eighth of a mile from this crater, 
fissures are opened in the earth, out of which scalding steam and smoke 
have issued from time immemorial, and affording heat enough to cook 
for an army.”—Honolulu Commercial Advertiser, Dec. 10, 1864.
