Mauna Loa in Eruption, 1880.

On November 9th, about 8 p.m., the above flow started a branch along the slope and face of the 

 mountain towards Kapapala ranch, Kau, and is still on its journey, making, I should judge, eight 

 to ten miles a day.

 Loa, and a few hours later from Hilo on the northeast. In both cases the lava foun- 

 tains were distinct, leaping high into the air. This was quite like all former recorded 

 eruptions, but in one way this differed from them all, and that was in the diffuse way 

 in which the streams were poured out; the length of time the lava poured forth was

 run north bj' east towards Mauna Kea, bitt this stopped after a course of twelve 

 miles, not far from the sheep station of Kalaieha on the high plateau between the 



great mountains of Hawaii. I have .seen the end of that stream and it presents no
