THE GREAT ERUPTION OF SA.KURA-JEMA IN 1914. 55 



abundant globiilitic bodies, and is often locally decolorized, ap- 

 pearing macroscopically as light flecks. The pyroxene may be 

 mostly enstatite-augite as in artificial slags. Magnetite and feldspar- 

 microlites are wanting in the I'ocks from Inoko-jima, while in 

 those of other islands magnetite-dust and skeletal plagioclase- 

 microlites occur in moderate quantity. The rock is cloddy, due to 

 contraction-fissures variously traversing the whole body, formed by 

 a sudden quenching of the hot mass in water, the clefts so pro- 

 duced are afterwards fined with a limonitic substance, and filled 

 with black dust which marks the direction of flaws. 



Some of these characteristics differentiate the subaqueous from 

 the lavas of subaërial consolidation.

AcTrïSY (1779-80) echoed for many years. 



1781 On April 11th, 1781 (10th year of An-ei, or 1st 

 year of Temmei era), an eruption took place (where ?), and the 

 people in the island were greatly frightened. They made a vow 

 to the God of the mountain, and refrained from fishing on the 

 18th (lunar calender) of every month. This day they still keep. 

 While the writer was in Kagoshima last year, he heard people 

 talking about this sacred 18tli, whicli had lately not been strictly 

 observed by the inhabitants, causing tl^e wrath of the God Gongen 

 whose shrine is located on a fittle elevation (400 m.) on the western 

 slope, and the principal centre of the late eruption on the western 

 flank was near the said shrine now entirely blown off with the hill. 



1782 On January 18th, 1782 (2nd year of Temmei era), 

 the mountain Was active ? 



1783 On September 3rd, 1783, it sent out flames, and ash 

 fell as far as Kyoto.
