for a moment for the influx of magma into them. The earthquakes 

 revived afterwards till noon ; the climax, however, had already- 

 been reached during the night before. The insular population felt 

 the strongest shock at about 5.30 a.m. 



Then surface activity was drawing closer. At about 8 a.m., 

 white filaments of misty clouds were seen to rise after an earth- 

 quake near the Gongen shrine^^ at an elevation of 300 m. on the 

 west slope facing Kagoshima, while at about the same time the 

 Hot and saliuc hot-spriug, and wells at Ari-mtira on the sou- 

 Springs tlicm foot spoutcd iu fouutaius to a height of 1 m. 

 It will be remembered that this village was afterwards buried 

 under ' live ' lava. The cold mineral spring at the water's edge 

 in Saidô on the northern shore spouted at about 8.30 a.m. As the 

 spot is known by the name of Yuno-saki or the ' hot-spring point,' 

 it is likely that formerly the spring possessed a high temperature. 

 The outgushes of this and other springs all round the island may 

 not necessarily be attrilnitable to subterranean pyrogenic origin ; on 

 the contrary, the writer is rather inclined to assign the cause to 

 disturbances of drainage by the constant shaking and trembling 

 high up in the body of the volcano. 



At 9.10 A.M., a thread of white steam clouds (Text. -fig. 14 a) 

 rose upright from the southern top-crater (Minami-daké) where two 

 weak solfataric vents had l)een constantly emitting vapors from 

 the inner cliff ever since the activity of 1879.'^ It was a sure sign 

 of surface activity, as the lava canal is directly connected with 

 the crater. In the An-ei eruption of 1779, the same pioneer erup- 

 tion happened in one of the three top-craters. {See Fig. 10 a, p. 44.) 

 About five minutes later, an earthquake (scale 3) happened 

 associated with cannonading sounds and tremblings, and then the
