Nakashiina^^ (Le.) Avas inclined t(j believe this one to be younger tlian 

 Ivita-dake. The Avriter consider.? the north pit to be the first-born, 

 then comes the southern, and the middle pit to l)e the yoinu/esf of the

 of the southern pit craters on the cirque-like explosion ('?) cliff near the

1) The writer fully endcjrsos the \ie\v expressed l)y the Lite Nakashima from a i^etrographic 

 standpoint, since the light C(jlored salic hyi^ersthene-andesite of the n(jrth cone greatly differs 

 from the black femic sempatic two-pyroxene andésites of the middle and south cones, which 

 sometimes even contain an accessory of olivine. The only question left for future consideration 

 is : AVliich has the precedence, the mid<lle or the soiitli cones, in their birth ? 



As may be seen in the photographic view taken from the top of the north cone (PI. Y. Fig. 1), 

 the southern margin of the minor and shallow crater of Naka-daké is sharply cut off by the 

 southern bottomless giant of Minami-daké, without being in the least ditfiijured by the grand 

 explosion of its southern neighbor. On seeing the mutual relation of both j^it-craters, the writer 

 is rather inchned to believe that the middle crater is the younger of the t\\o. K. Vamaguchi 

 believes the middle pit to be simi>ly a ])Ortion of the stemmed-up lava-flmv of the south cone.
