Notes on the 1916 Eruption of Mauna Loa

The writer's observations and comments on this eruption divide naturally into four parts: I. Distant observation and photographic record of the outbursts of fumes on May 19, and of the beginning of flow on May 21-22, 1916. II. Observation at the front of the Honomalino branch of flow on May 23. III. A hurried reconnaissance of the Kahuku branch of flow, and of the flow-source region, on May 30-31. IV. A thorough examination and photographic record of conditions throughout the region of the source of flow, made in the company of Dr. A. L. Day, in the six days, June 28-July 3, 1916. Treatment under these headings makes for a somewhat extended and rambling account; but it has been found very difficult to present the complicated sequence of observations, which in some respects are unrelated, in any more succinct way.
