from a prolonged dive.

At midnight a tremendous sea struck her, and for a minute you could
not see the yacht at all, as she was completely enveloped in spray and
foam. Tom said it was just like being behind the falls of Niagara,
with the water coming over you from every quarter at once. It was only

flame would shoot up and pierce through the overhanging cloud to the
heavens above, while the molten lava rose like a fountain for a short
distance, and then ran down the sides of the mountain. It was
