last year. The latter crater is very active ; it is half a mile in diameter, 
and 250 feet deep from the “floor” of Kilauea, and in this awful fiery 
chasm the waves of liquid lava are continually moving—irresistibly drawn 
to the centre, the seething whirlpool, where masses of lava are fused like 
blocks of sealing wax, and where great fountains of brilliant lava are 
hurled high up in the air! Kilauea is 300 miles from Honolulu, and the 
volcano is 4,000 feet above the sea-level. It took the travellers over an

“ And whereas the Legislature of the Province of Ontario passed an
