THE GREAT EKLTTION OF .SAKIJllA-JIMA IN 1914. 43 



1478 The after-eiTects continued till 1478, when the moun- 



tain erupted again and the slu^re of Fukuyama on the op}30.site coast 

 of Osunii was converted into a desert by rains of ash and pumice. 

 During the whole period the Kirishima group, tlie northern 

 neighbor, kept a profound silence, or at least there is no record 

 of its activity. In loo 4 (23i'd 3^ear of Tembun era) and 1556 

 (2nd year of Koji era), Kirishima was, however, active. In 

 1615 (1st year of Genua era) Kaimon, this time the southern 

 neighbor, made a great eruption. Thus, while Kirishima and 

 Kaimon were displaying activity from 1554 to 1615, Sakura- 

 jima was not in the least affected.

1) In reatling the phrase, *■ the mount ' bnrnt ' or erupted," we must guard agiinst 

 falling into mistake. To cite an exam^jle, the writer found in the record of the same year the 

 following clause : The Sakura-jima shrine located on the sloi)e of the south crater about nine- 

 tenths from shore was burnt by accident from the tobacco pipe of a farmer of Akamizu.
