Art, LIV.—Notes on American Earthquakes, No. 14; by 
; C. G. Rockwoop, Jr., Princeton, N. J. 
IN this article, as in former ones of the series, I give a sum- 
Mary of the information which has come into my hands in regard 
to earthquakes which occurred during the preceding year in 
North or South America and the adjacent waters. The infor- 
Mation has been gathered from various sources, largely from the 
Monthly Weather Review of the U. S. Signal Service, and 
from current newspapers; but I have also been fortunate in re- 
Celving a greater number than usual of manuscript reports, mostly 
relating to the shock of Aug.10. For many of these my thanks 
are due to Cleveland Abbé of the Signal Service, and especially 
to W. M. Davis of Harvard College, who kindly put into my 
hands a large amount of matter, both manuscript and printed, 
Which he had collected. The persons, whose letters to these 
‘wo gentlemen I am reaping the benefit of, are too numerous to 
> mentioned here by name, but putting their contributions 
with my own collection, I find that I have at command about 
One hundred and fifty direct manuscript reports on the earth- 
quake of Aug. 10, besides a very large amount of newspaper 
Cuttings, For other.reports I am, as heretofore, indebted to J. 
M. Batchelder of Cambridge, Mass., and to Charles Carpmael 
= Toronto, Superintendent of the Canadian Meteorological 
rvice, 
As in former notes, when a shock is recorded on the authori- 
ty of asingle report, the source of the information is indicated,
