flows are lost sight Of. During the
eruption of last March some Of the
visitors came near being cut off by
the streams Of lava which flowed over
the enormous sink that surrounds the
main crater. Even small children ven
tured close to the tapping columns of
molten froth that rolled out of the
fiery pit.
Hotel at Crater's Edge.
Upon the very edge of the big crater
is built the Volcano house, a modern
hotel where the guests may view the
performances of the restless monster
from the windows of their rooms or
from the restful chairs upon the We
randas. Many times during the day
light tremors of earthquakes may be
felt mt the hotel, and on all sides of
the building white fumes of sulphur
constantly pour forth from cracks in
the lava formation. For miles around
the main crater Of Kilauea are to be
seen evidences of vast destructiveness
wrought by the volcano in times past.
all going to show that its present long
period of comparative passivity may
be only a prelude to another disas-
trOus performance.
1t Is at Kilauea that the most thor
ough scientific study of volcanoes and
earthquakes ever undertaken is in
progress. This work Is in charge OF
Prof. Thomas A. Jaggar, Jr. He con-
ducts an observatory and seismolog-
cano, where every phase and move
ment Of the lava pit and the earth ire
mors are recorded day by day. This
research work has already resulted In
many valuable discoveries. some of
which promise to be of much practical
value in the future, 1t is asserted.
For one thing, the conclusion has
been reached that the underground
fires of Kilauea may be used for indus
trial purposes. At the last session of
the Hawaiian legislature bill was in
troduced appropriating $4,000 to
make borings in the floor of the big
crater to test the heat supply for
power purposes. While this measure
failed of final passage because of the
rush of other measures that were
deemed of more Importance, 1t Is re-
garded as practically assured that the
next legislature will make the desired
appropriation. 1t is stated that the
use Of this heat in large power plant
or piping II to sugar mills and other
industries could be easily accom-
plished.
