^ The field observations upon which this paper Is partly based were made In the sum- 

 mer of 1905, in connection with a general geological study of the Yakutat Bay region by 

 a U. S. Geological Survey party under the direction of Prof. R. S. Tarr. A grant of 

 money, obtained through the assistance of the American Geographical Society of New 

 York, made it possible for the author to accompany this party as special assistant In 

 physiography and glacial geology. 



The office work upon which this paper is more largely based was done during tiie 

 winters of 1906-8, at the University of Wisconsin, in connection with the preparation 

 of a U. S. Geological Survey professional paper by R. S. Tarr and the author, dealing 

 with these earthquakes and now in preparation. 



Acknowledgment is made to H. P. Ritter and R. D. Oldham for the loan of manu- 

 script notes, to H. F. Reid and the U. S. Coast and Geodetic Survey for newspaper 

 clippings, to many seismologists for data, to many persons in Alaska and Canada for 

 replies to earthquake circulars, and to R. S. Tarr and G. K. Gilbert for suggestions re- 

 garding the subject-matter of this paper. 



The paper Is published by permission of the Director of the U. S. Geological Survey.
