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

 from 5 to 6 miles inland, and about 90 feet above the sea. They 

 <'.re close to the water, and from i to 10 feet above it. The 

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

 \/as 204° F. in February, 1899. In another it was 194°. The 

 \/ater was probably at the boiling-point in some cases as it entered 

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

 \ ave no recollection of deposits of any extent around the springs. 



13. The Hot Springs of Vunimoli on the Lambasa 

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

 fiom 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 

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

 square basins which receive the waters. The temperature of the 

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

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

 d ;posits. These springs lie about 8 miles inland and are rather 

 o/er 100 feet above the sea. They are, however, small and un- 

 iriportant, 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. 

 T ley issue copiously from the volcanic agglomerate at a tempera- 

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

 fr )m the river, and a foot or so above it. Algse flourish in the 

 w Iter, and siliceous sinter incrusts the rocks. 



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

 or THE Wai-ni-koro River.— a few hundred yards from the 

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

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

 th ; water, which in September, 1899, had a temperature of 97° F. 



16. The Hot Springs of Natuvo on the North Coast 

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

 vil age 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 

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