1910. He also prepared a beautifully illustrated " Monograph on 

 the Yakutat Bay Region, Alaska, Physiography and Glacial 

 Geology " which was published in 1909 as Professional Paper 

 No. 64 of the U. S. Geological Survey. He assisted in the prepa- 

 ration of the " Watkins Glen-Catatonk Folio " (published the 

 same year by the Survey) comprising the area of two 15-rninute 

 quadrangles immediately surrounding Ithaca and Cornell Uni- 

 versity. Among his published papers are also numerous contri- 

 butions to scientific and educational journals. 



He was vigorously at work up to a few days of his death. 

 The correcting of proof-sheets of a Professional Paper for the 

 IT. S. Geological Survey on " Alaskan earthquakes " and the 

 writing of a text-book on "Advanced Physiography" were 

 brought to a close by his death. During the past winter he had 

 been actively engaged experimenting upon glacier and pond-ice, 

 seeking evidence of the determining causes and conditions of the 

 motion of glaciers. Dr. O. D. VanEngeln was assisting him in 

 these experiments and will continue them and prepare the record 

 of the experiments for publication. A scientific account of his 

 four expeditions to Alaska to study its glaciers had but recently 

 been finished. Professor Lawrence Martin was associated with 

 him in its preparation and will complete it for publication. He 

 was also looking eagerly forward to making further explorations in 

 Newfoundland during the coming summer when his life was sud- 

 denly terminated. Professor Tarr was one of the first American 

 teachers to give university rank to the physical geography of the 

 high school curriculum. His training under Davis at Harvard 

 specially fitted him for the task and at Cornell he found the 

 opportunity to build up a well-equipped physiographic laboratory 

 for the scientific teaching and investigation of the problems of 

 physiography. He was a vigorous explorer, a keen observer, a 

 ready speaker, an interesting and inspiring teacher and will be 

 greatty missed not only by his niany pupils but by physiographers 

 at home and abroad, among whom he had already attained high 

 rank. He was President of the Association of American Geog- 

 raphers, foreign correspondent of the Geological Society of 

 London, fellow of the Geological Society of America and member 

 of other scientific and educational societies ; and associate editor 

 of the Journal of Geography and of the " Bulletin " of the Ameri- 

 can Geographical Society and corresponding member of La Com- 

 mission Internationale des Glaciers. h. s. w. 



Professor A. Laavrence Rotch, the meteorologist, died on 

 April 7 at the age of fifty- one years. In 1885 he established and 

 subsequently maintained the Blue Hill Meteorological Observa- 

 tory. He was the first to use kites in the recording of the mete- 

 orological data of the upper atmosphere, and through this work, 

 his investigation of clouds and in other similar lines, his contri- 

 butions to science were numerous and important. 



Professor Osborxe Reyxolds, distinguished for his impor- 

 tant contributions to engineering and theoretical physics, died on 

 February 21 at the age of seventy years.
