he published his famous work on the Geology and Mining Industry 

 of Leadville, which was of great utility in directing attention 

 to the importance of scientific enquiry as a preliminary to the 

 exploitation of a mineral region. Other important works dealt 

 with the secondary enrichment of ore-deposits, with theories of 

 ore-deposition, and with the geolog}' of the Green Eiver and the 

 Uinta Mountains. His influence on the development of the more- 

 scientific side of economic geology has been much felt among the 

 younger men of America. 



E,0BEET Dayies Eobeets was born at Aberystwyth in 1851,. 

 and educated at University College, London, and at Clare College,. 

 Cambridge, where he took a first class in the Natural Sciences 

 Tripos in 1874. He proceeded to the M.A. degree at Cambridge 

 and the D.Sc. in London in 1878 ; was elected to a Fellowship at 

 Clare in 1884, and became University Lecturer in Geology in the- 

 same year. He had much to do with the organisation and success^ 

 of the Cambridge University Extension Lectures, and also of 

 those of London University, and eventually he became Registrar 

 to the Board to Promote the Extension of University Teaching in 

 London in 1902, a post which he held till his sudden death on 

 November 14th, 1911. He was closely associated with, the 

 University of Wales, and was Chairman of the Executive Committee 

 in 1910-11. He was also High Sheriff of Cardiganshire in 1902-3. 

 His chief interests were bound up with educational questions, and 

 for many years he was Lecturer and Secretary to the Gilchrist 

 Trust, for which, as well as for the University Extension movement, 

 he frequently delivered lectures to large audiences. He was a lucid 

 and capable lecturer, and a most painstaking teacher. His duties 

 did not allow him time to attend many meetings at this Society, 

 or to complete any extensive research ; but he published papers ^ 

 chiefly concerned with the pre-Cambrian rocks of North Wales, in 

 the ' Geological Magazine.' His chief interests, however, especially 

 in his later life, lay on the physiographic side, the borderland 

 between Geology and Geography, and he was especially fond of 

 problems connected with river development and the growth of 

 landscape. He devoted many of his holidays to field work in 

 association with investigators on these lines, and was a whole- 

 hearted advocate of the application of Prof. W. M. Davis's methods 

 of work to this country. He published ' An Introduction to 

 Modern Geology,' and his teaching had considerable influence in 

 directing the young men at Cambridge and in many of the more-
