was vigorous and the light vivid, the lavas never overflowed the rim of 
the great crater or burst out laterally. Like most of the eruptions in 
Kilauea, the action was confined within the walls of the old jae 
In n May, June, and July, the action in Kilauea was grea ased. 
It was often intense and vehement. ‘The old south lake (Halonteu9 
overflowed several times, and a chain of lakes, three, four, and sometimes 
@ or six, opened on a curved line from N.W. to N. and N.E. from 
the old lake. The action in this chain of lakes was often violent. Jets

yawning fissures opened, interrupting the stose e in crossing the bottom 
of the crater. At different times, and sometimes for many days, the 
fiery flood swept up to the path by which priori go into the crater and 
cut off all ingress by the usual route. Many parties were obliged to 
view the surging waves from above, without being able to enter the crater.
