was a stream of lava, rolling and surging and beating against
huge, precipitous, red-hot cliffs; and, higher up, suspended from other,
also red or white hot overhanging cliffs, depended huge stalactites, like
masses of fiercely glowing fern leaves waving about in the subterraneous
wind; and here we saw how thin was in some such places the crust over
which we walked, and how near the melting-point must be its under surface.
For, as far as we could judge, these little craters or cones rested upon
a crust not thicker than twelve or fourteen inches, and one fierce blast
from below seemed sufficient to melt away the whole place. Fortunately
one can not stay very long near these openings, for they exhale a very
poisonous breath; and so we were drawn back to the more fascinating but
less perilous spectacle of the lakes; and then back over the rough lava,
our minds filled with memories of a spectacle which is certainly one of
the most remarkable our planet affords.
When you have seen the fiery lakes you will recognize a crater at sight,
and every part of Hawaii and of the other islands will have a new interest
for you;

for all are full of craters, and from Kilauea to the sea you may trace
several lines of craters, all extinct, but all at some time belching forth
those interminable lava streams over which you ride by the way of the Puna
coast for nearly seventy miles back to Hilo.
I advise you to take this way back. Almost the whole of it is a land of
desolation. A narrow trail across unceasing beds of lava, a trail which
in spots was actually hammered down to make it smooth enough for horses'
feet, and outside of whose limits in most places your horse will refuse to
go, because he knows it is too rough for beast or man: this is your road.
Most of the lava is probably very ancient, though some is quite recent;
and ferns and guava bushes and other scanty herbage grow through it.
In some of the cavernous holes, which denote probably ancient cones or
huge lava bubbles, you will see a cocoa-nut-tree or a pandanus trying to
subsist; and by-and-by, after a descent to the sea-shore, you are rewarded
with the pleasant sight of groves of cocoa-nuts and umbrageous arbors of
pandanus, and occasionally with a patch of green.
Almost the whole of the Puna coast is waterless. From the Volcano House
