Dr. Hill Has Had One of the Most Distinguished Careers 

 in American Science 



He is an author with over 200 titles to his credit. He has been a member 

 of practically every learned society covering his field of activity, among 

 which may be mentioned: Medalist, Geologique Societe de France; Amer. 

 Assoc, for the Adv. of Science; N. Y. Acad, of Sci.; Wash. Acad, of Sci.; 

 Geographical Soc; Amer. Geographical Soc; Southwestern Geological Soc; 

 Branner Geological Soc; Geological Soc. of Amer.; Natnl. Geographical 

 Society; Washington Philosophical Soc; Seismological Soc. of Petroleum 

 Geologists (honorary membership bestowed 1926, "in consideration of his 

 valuable contributions to the science of petroleum geology"); etc His career 

 with the U, S. Geological Survey extended from 1885 to 1925, during which 

 period he was advanced to the positions of executive Officer and Senior 

 Geologist, being honorably retired from the latter position. 



Tributes to Dr. Hill's work: 



J. B. Lippincott: "Dr. Hill was definitely assigned by the U. S. Geological 

 Survey to special studies for it in Southern California between 1913 and 1917 

 and he has continued these studies with some interruptions for a period of 

 fifteen years. He has devoted his time particularly to investigations of the 

 fault lines and earth movements that have occurred in the geologic past in 

 this section, and is undoubtedly the best-posted and highest authority that we 

 now have on this subject." 



George Otis Smith, Director U. S. Geological Survey: "Your work on 

 the geology of Texas ... is the foundation on which rests the results 

 obtained ... by investigators who have worked on that general area." 



Faculty of the University of Texas; "You laid a foundation in Texas 

 geology on which those of us who are row working in the State are striving 

 to build. Your name and your publications will remain so long as the science 

 of geology continues." 



Bulletin of the Geological Society of America: "He was associated with 

 Alex. Agassiz in explorations of Central Amer. and the West Indies. . . . 

 His contributions to the geology of Mexico, Panama, Costa Rico and the West 

 Indies were important. In fact, wherever he went he made valuable contri- 

 butions to the ftind of geologic information. He is perhaps the first recon- 

 naissance geologist of his day." 



Oklahoma Geological Survey: "You have added to our store of knowledge, 

 until now for many years you have been regarded as the world's greatest 

 authority on this subject." 



Dr. T. W. Vaughan: "His work constitutes one of the greatest single 

 contributions to knowledge of the Cretaceous of the enormous interior region 

 of the U. S. . . He broke down a dam which had held back the knowlaige 

 of the geology of a large part of the continents of both North and South 

 America. . . . Hill's work constitutes one of the most important indi- 

 vidual records in the geology of this country. All of us should be proud of it." 



Chas N. Gould: "Dr. Hill's work on the geology of the southwest was 

 basal, fuiidamental, and will stand the test of centuries." 



T. C. Chamberlin of Chicago University: "Paper on the Comanchean that 

 has become one of the guideposts of our science." 



Douglas Johnson of Columbia: "I belong to that very large number who 

 have been your disciples. . . . very high opinion of which he has of your 

 epoch-making contributions to American geology" 



P. S. Smith, Acting Director U. S. Geological Survey: "He is one of the 

 most able of American geologists, has an enviable national reputation and 

 has contributed greatly to the foundations on which geologic science rests." 



l)avid White, National Research Council: "Your work has stood the 

 test and is still the standard."
