128 ART. 3.-B. KOTO: 



were formerly outside the reach of rollers, and in April the writer 

 frequently overheard people talking about the land settling 2 or 

 3 feet. 



The same thing happened after the eruption of 1779. It 

 is stated'^ that the sea encroached upon the city of Kagoshima 

 and its northern extension of shore by a subsidence of 5 or 6 and 

 even 10 1 feet. The immerged land seems to the writer to have 

 been later reclaimed, though some recent writers entertain the 

 view that the lost land resumed its former altitude after a score 

 of years. The bottom of the trench bay, or geologically speaking 

 the rift valley, of Kagoshima is settling even at present, as will be 

 immediately spoken of. 



As to the recent positive movement of sea level, a popular 

 view is that the current is now being deflected and stemmed to 

 the opposite shore through the complete damming up of the strait 

 of Séto by the new lava-flows (p. 90 and Text-fig. 19 in p. 74), 

 wliile a few assign the cause to the increment of water tempera- 

 ture through the inflow of ' live ' lava into the sea. 



Thanks to the authority-^ of the Ordnance Department of The 

 Headquarter Staff of our Army, the writer was given all the 

 available data of former and recent levelings undertaken with the 

 express purpose of ascertaining the changes, if any, of levels in 

 the neighborhood of the volcano after the paroxysmal activity. 

 The resurvey resulted in the affirmative, and more than that, the 

 local disturbance was found to be confined within a circular tract 

 having a theoretical radius of 61 hn., conforming to that post-
