Ill THE HOT SPRINGS 33 



come up in half-a-dozen places on either bank of the river, and are 

 from S to 6 miles inland, and about 90 feet above the sea. They 

 are close to the water, and from i to 10 feet above it. The 

 temperature of one small pool, where the water bubbled up briskly, 

 was 204° F. in February, 1899. In another it was 194". The 

 water was probably at the boiling-point in some cases as it entered 

 the pools, and in the others it could have been only a few degrees 

 below it. The rocks of the district are agglomerates and tuffs. I 

 have no recollection of deposits of any extent around the springs. 



13. The Hot Springs of Vunimoli on the Lambasa. 

 River. — A few minutes' walk from Vunimoli, and about 100 yards, 

 from the left bank of the river, these hot springs issue in a place 

 named Vunimbele from the foraminiferous clay rock (soapstone) of 

 the district. They are on the side of a ditch which communicates 

 with the river. The natives have cut out of the soft rock small 

 square basins which receive the waters. The temperature of the 

 hottest spring in August, 1899, was 155° F. That of others 

 was 140°. The conditions are not favourable for the formation of 

 deposits. These springs lie about 8 miles inland and are rather 

 over 100 feet above the sea. »They are, however, small and un- 

 important, and the locality in which they occur is now overgrown 

 with vegetation and not easy to discover. 



14. The Hot Springs of Mbati-ni-kama on the Ngawa 

 River. — These springs are situated in the Lambasa district about 

 7| miles from the coast, and rather over 100 feet above the sea. 

 They issue copiously from the volcanic agglomerate at a tempera- 

 ture of 161° F. (August, 1899), and are only removed a few paces 

 from the river, and a foot or so above it. Algae flourish in the 

 water, and siliceous sinter incrusts the rocks. 



15. The Hot Spring of Nandongo on the Head-Waters 

 OF the Wai-ni-KORO River. — A few hundred yards from the 

 village and elevated about 180 feet above the sea there is a small 

 pool in the clay of the river bank, 2 or 3 feet above and close to 

 the water, which in September, 1 899, had a temperature of 97° F. 



16. The Hot Springs of Natuvo on the North Coast 

 OF Natewa Bay. — About a mile east of Mbiagunu and near the 

 village of Natuvo, there are two hot springs of small size which I 

 visited in August, 1899. One that issued on the reef-flat from the 

 coral-rock at a temperature of 136° F. was covered over towards
