 constructed bv the writer on the data of levelings by the General Staff of our 

 Armv before and after the eruption of the volcano in 1014. The values with 

 the minus sign prefixed, e.g., — Sd^mm. near Cape Osaki, indicate the

 the first levelings of 1892-1900 and the relcvelings of July-August of 1914, 

 i.e., after the catastrophe of January. Those values enclosed by parentheses 

 prefixed with the minus sign, e.g., — (055 mvi.) show tlie subsequent progressive 

 subsidence of the local crust after 215 days ascertained by the third levelings.
