speaking, a single gigantic konide, having an altitude of 1,133.5 ???., 

 and standing on an irregularly round base of 8 Lm. in diameter, 

 which approximately coincides with the present dimension of the 

 island. The main crater-cone is Kita-dakk {MUiacJii) or the north 

 crater-cone (homate).

Later, the two other apical craters, the south and tlie middle, 

 were created, the former being comparable in magnitude witli the 

 main ; and the total morphological aspect of tlx^ mountain top 

 presents that of a triple volcano, although the two later ones are 

 really parasitic to the main, the iiorth cone. The reason why they 

 are so ca.n be readily understood from the wide distribution {sec 

 Geologic Map) of the Hght-brownish (jvmj lava {Mihachl lava), 

 which characterizes the material of the main body of the volcano 

 and the crater- wall of the north cone.
