Barlow's writings, published either as official reports or memoirs 

 issued by the Geological Survey of Canada or the Department of 

 Mines at Ottawa, or by various other Governments, institutions, 

 societies, etc., form a progressive series of Geological investigations, 

 involving extensive field-work covering many summer seasons, labor- 

 atory and office work, close microscopical examinations linked with 

 petrological researches and chemistry, presented in clear, attractive, 

 accurate and forceful as well as practical manner. His keen powers 

 of observation coupled with his graphic description of the various 

 mineral deposits and areas studied did much to make his numerous 

 writings eagerly sought, not only by the practical miner but also by 

 the ardent student and professor of Geological Science, In all his 

 geological labours Dr. Barlow made laboratory work the handmaid 

 of field work with remarkable success. He ofttimes pointed out to 

 his confrères the value and necessity of close microscopic investi- 

 gation in the office following detailed field exploration in a given 

 geological area. He also recognized many geological provinces in 

 Canada constituting centres of geological problems of a fascinating 

 nature and, from his experience of some thirty years work in the 

 crystalline rock-formations of Canada, he had begun to correlate and 

 co-ordinate results when he was so suddenly removed by death. A 

 bibliography of his work comprises some sixty volumes, reports, 

 memoirs, papers or pamphlets from 1890 to 1915; his last "memoir" — 

 a posthumous work — was only very recently issued (May, 1915), 

 from the Department of Mines Press. From his numerous 

 writings may be gauged the great volume of his work. Dealing 

 at first with the nickel and copper deposits of Sudbury, in the Province 

 of Ontario, Canada, he pursued further studies of the Archaean com- 

 plex in the Laurentain and Huronian areas of Lakes Huron, Timagami, 

 Timiscaming and Keepawa. His elaborate monograph of the Lake 

 Timiscaming district forms a classic; whilst his careful researches in 

 the Haliburton region of southeastern Ontario added much to our 

 knowledge of that complicated region. During his geological ex- 

 plorations Dr. Barlow made carefully selected collections of geological 

 specimens with a view of illustrating the precise geological characters 

 and physical appearance of the rocks found in the areas examined. 

 These are preserved in the National Museum at Ottawa and comprise 

 a vast amount of material, much of which has been exhibited or will 

 be in the near future. 



In 1912-13, he devoted much time and labour to the preparations 

 and carrying out of the International Geological Congress and accom- 

 panied the excursions to the Maritime Provinces, Cobalt, Haliburton, 

 Sudbury, and British Columbia. His lucid and logical expositions of
