part 1] ANNIVERSARY ADDRESS OF THE PRESIDENT. lvii 



o£ this Society. The majority of them deal with the Carboniferous 

 Svstem or with the 2>eolo£v f Xorthern England. He also wrote 

 a useful book on the Geology of Northumberland <fc Durham, which 

 has passed through more than one edition ; and the geological 

 article in the Victoria County History of Durham is from his pen. 

 But his interests were not confined to this side of the subject. 

 He was an active member of several important committees of the 

 British Association, among which may be mentioned the committees 

 on Underground Temperatures and on the Conductivity of Rocks. 

 A large proportion of the work of the latter committee was carried 

 out at Newcastle under his supervision and that of his colleague, 

 the late Prof. A. S. Herschel. Another question to which he 

 devoted a considerable amount of attent?' ?i in his earlier years was 

 the influence of geology on public hea.cli: and on this he wrote 

 several articles, including one on the distribution of goitre. 



But it is not by his published work that his students will chiefly 

 remember him. He was an admirable lecturer and a most genial 

 and sympathetic teacher, whose pupils became his friends and 

 remained his friends for life. In his later years an affection of 

 the foot, characteristically disregarded as of no moment, at length 

 compelled an operation which left him lame, and incapacitated him 

 for. field work, but his cheerfulness remained unimpaired. His last 

 illness was long, lasting for several months, and he died at his 

 home at Corbridge on February 7th. 1918, in his 71st year. 



He had become a Fellow of the Society in 1S70, and the 

 Murcbison Medal was awarded to him in 1904. [P. L.] 



The veteran American geologist Arnold Haote had been a 

 Fellow of this Society since 1880. In the early days of his career 

 he took part in Clarence King's Exploration of the Fortieth Parallel 

 and in other pioneer work in the West, and he also carried out 

 special missions for the Governments of Guatemala and China 

 From 1S70 he was attached to the United States Geological Survey, 

 and took a leading part in geological investigations in the Western 

 States. His most important works are the ' Geology of the Eureka 

 District, Xevada ' ( 1892) and the ' Geology of the Yellowstone 

 National Park* (1S99). the latter written in collaboration with a 

 number of colleagues. Hague's kindly disposition and personal 

 qualities gained for him a large circle of friends. He was President 

 of the Geological Society of America in 1910, and, among other 

 honours, the degree of Doctor was conferred upon him by Columbia
