Grove Karl The passing of Dr. Gilbert after almost seventy-five years 

 Gilbert* of activity deprives geological science of one of its ablest 

 and most honored representatives. It is permitted to few 

 men to leave an equally enviable record. To an unusual degree his work 

 was distinguished by keenness of observation, by depth of penetration, 

 by soundness in induction, and by clarity of exposition. It is doubtful 

 whether the products of any other geologist of our day will escape re- 

 vision at the hands of future research to a degree equal to the writings 

 of Grove Karl Gilbert. And yet this is not assignable to limitation of 

 field, or to simplicity of phenomena, or to restriction in treatment. The 

 range of his inquiries was wide, his special subjects often embraced in- 

 tricate phenomena, while his method was acutely analytical and his 

 treatment tended always to bring into declared form the basal princi- 

 ples that underlay the phenomena in hand. 



In the literature of our science the laccolith will doubtless always be 

 associated with the name of Gilbert. In its distinctness as a type, in its 

 uniqueness of character, and in the definite place it was given at once 

 by common consent, one may almost fancy a figurative resemblance be- 

 tween the laccolith and its discoverer and expositor. Gilbert's mono- 

 graphs on the Henry Mountains and on Lake Bonneville will long stand 

 as unexcelled models of monograph treatment. His contributions to 

 physiographic evolution, particularly his analysis of the processes that 

 end in base-leveling, link his name with that of Powell, and give to 

 these two close friends a unique place as joint leaders in interpreting 

 morphologic processes. Glacial and hydraulic phenomena were also 

 fields in which Gilbert's powers as an investigator and expositor were 

 signally displayed. 



In accuracy of delineation, in clearness of statement, and in grace of 

 diction Gilbert's contributions are certain long to stand as models of the 

 first order. His personality was of the noblest type ; he was a charming 

 companion in the field; he was a trusted counselor in the study. The 

 high place he has held in the esteem of co-workers is quite certain to 

 merge into an even higher permanent place to be accorded him by the 

 mature judgment of the future. T. C. C.
