Tue Committee asks to be reappointed with a grant of 60). 
The death of John Milne, in July 1913, creates a situation of 
some difficulty and anxiety. He organised a world-wide seismological 
service with very little financial help from others. In many of the 
outlying stations the instrumental equipment was provided either by 
himself or by one of his friends, and the care of it has been gener- 
ously undertaken by a volunteer who is often busily engaged in other 
work. The collation of results was in the early years undertaken by 
Milne himself, with the able help of Shinobu Hirota. Of late years 
a subsidy of 200]. a year from the Government Grant Fund allowed 
of paid assistants; and Shinobu Hirota thus obtained a well-deserved 
official position; but for many years the only salary he received was 
paid from Milne’s own pocket. It is by no means certain that the 
volunteer services at the stations, and the subsidy from the Govern- 
ment Grant Fund which makes it possible to keep running the 
central station at Shide, can be long continued; and it seems in 
any case very improbable that they can be rendered permanent. 
But a much more serious difficulty is the want of a salary for a 
Director or Superintendent of the whole British network of stations, 
who can give undivided attention to the valuable results which they 
have accumulated and to which they are daily adding. The salary of
