MEMORIAL OF JOSEPH BARRELL 25 



greatest infiuence are his papers on isostasy and those dealing with the 

 origin of continental and littoral sediments. A proper evaluation of 

 these contributions can only come from men who are masters of the 

 subjects. 



In response to my request for a statement regarding the character, 

 scope, and significance of BarrelFs work on isostasy, Dr. William Bowie 

 has submitted the following : 



1 wish to take this opportunity of expressing my deep appreciation of the 

 very valuable contribution made to the literature on the theory of isostasy by 

 Prof. Joseph Barrel). His work was far-reaching and thorough and threw 

 much light on the relation of isostasy to geology. In fact, Barrell did more, 

 in my estimation, to bring the geodesists and geologists together in the science 

 of isostasy than did any other investigator. Geodesists deeply feel the loss 

 of Barrell, for they were depending on him to lead thought in the application 

 of the theory of isostasy to geological science. 



Barren's work in isostasy will long be an inspiration to geodesists and geol- 

 ogists and his name will always be associated with those of Pratt, Diitton, 

 Hayford, and others who have made notable contributions to the knowledge 

 of isostasy. 



The group of papers which may be termed studies in sedimentation 

 reveal so fully the mental characteristics of Barrell, his methods of think- 

 ing, and the results and significance of his contribution that they deserve 

 separate treatment. To supply this need, T. Wayland Vaughan kindly 

 consented to prepare the paper on the work of Professor Barrell in prob- 

 lems of sedimentation."

The scientific reputation of Barrell rests on the papers listed below. 

 A complete list of titles would include 19 reviews, chiefly in the general 

 field of geophysics, 5 brief discussions of papers read before the Geolog- 

 ical Society of America, 3 abstracts of papers later published in full, and 

 4 contributions of local miiversity interest. 



As arranged chronologically, Barrelhs bibliography shows a develop- 

 ment of interest in the broad aspects of geology, and also the influence 

 of changed surroundings and associations. The engineer and mini no- 

 geologist is revealed in the papers published before 1906 and also in the 

 "Geology of the Marysville Mining District," which, though published 

 in 1907, is based on field-work done some years previously. After adjust- 

 ing himself to his routine work at Yale, Barrell entered whole-heartedly
