“5. The climate is uniform and the air clear for astronomical work.
“6. There are frequent small earthquakes, which are of great interest for technical reasons.
“7. The remarkable distribution of both hot and cold underground waters in Hawaii needs [[197]]careful study, and this has an important bearing on agriculture as well as upon science.
“8. The territory is American, and these volcanoes are famous in the history of science for their remarkably liquid lavas and nearly continuous activity.”
Professor Jaggar consequently advised those interested:
“1. To erect buildings on the brink of the Volcano of Kilauea, in which to house the instruments, library, and offices for working up and tabulating the statistics, records, and information obtained.
“2. To set apart a room for a local museum, to exhibit to visitors instruments, plans, diagrams, maps, and photographs. This will be of value in exciting interest with a view to securing an endowment.
“3. To welcome advanced students from either the Institute or other institutions for special work in the laboratory.
“4. To erect subordinate instrument stations, with self-recording instruments, and to employ voluntary observers, at various points hereafter to be determined. It is hoped that eventually some work will be done by the staff of the observatory in the study of tides, soundings, earthquake waves, and the movements of the coast line of the island. [[198]]
“5. To send expeditions to other volcanic and earthquake belts for comparative studies.
