channels of the streams. Such water is imfit 

 for household or even for manufacturing uses, 

 and tliough the coal refuse is not an organic 

 pollution, nor a chemical poison, its presence 

 in large quantities is a troublesome factor 

 to be considered when water filtration is pro- 

 jected. The distances downstream to which 

 this material persists under different flow 

 conditions will also furnish an interesting 

 subject for study. 



PuOFESSOB 1\ C. Chamberlin, of the Uni- 

 versity of Chicago, has had charge, during 

 the present season, of the investigations car- 

 ried on by the U. S. Geological Survey in the 

 deposits of Pleistocene age in the United 

 States. An important part of these deposits 

 consists of the gravel and till widely spread 

 over the northern tier of states by the inva- 

 sion of the great glacier during a late geo- 

 logical epoch. These gravels are of consid- 

 erable economic importance on account of 

 the clays found in connection with them in 

 certain localities. In the middle states they 

 are of importance on account of the water 

 retained by them, which is available for wells ; 

 while in the western states they are associated 

 with auriferous metals. Professor Chamber- 

 lin has been assisted by Professor Salisbury 

 and Mr. W. W. Atwood in the Rocky Moun- 

 tain region, by Prank Leverett and W. F. 

 Taylor in Michigan and by W. C. Alden in 

 Wisconsin. 



Through the influence of Director Stewart, 

 of the Experiment Station at West Virginia 

 University, and with the cooperation of some 

 prominent citizens of Morgantown, the U. S. 

 Division of Good Roads in the Department 

 of Agriculture has been induced to supervise 

 the building of three miles of good road in 

 Monongalia county. Work upon this piece 

 of model road is now going on. It extends 

 from the west end of the suspension bridge 

 at Morgantown down the river three miles, 

 to Randall. A portion of it is to be built 

 of Telford blocks, and the remainder is to 

 be a MacAdam road. Citizens furnish the 

 material and labor and the U. S. government 

 furnishes the machinery _ and supervises the 

 work. 



The Department of State has received from 

 theBelgiaxi legation, Washington, under date of 

 November 3, 1902, notice of the International 

 Congress of Hygiene and Demography, to be 

 held at Brussels from September 2 to Septem- 

 ber 8, 1903. An invitation is extended to 

 the United States to be officially represented, 

 and the wish is expressed, in behalf of the 

 Minister of Foreign Affairs, that committees 

 of propaganda, composed of persons eminent 

 in medical science and hygiene, be organized 

 in the different states, with whom the central 

 committee at Brussels may correspond. The 

 questions to be discussed will include bac- 

 teriology, microbiology, parasitology applied to 

 hygiene; alimentary hygiene, applications of 

 chemical and veterinary science, sterilization, 

 use of antiseptics ; sanitary technology ; indus- 

 trial and professional hygiene ; hygienic trans- 

 portation, best means of disinfection ; adminis- 

 trative hygiene, aim and organization of 

 medical inspection, quarantine regulations, and 

 supervision of tenement houses; colonial 

 hygiene, malaria, beri-beri, etc.; demography. 

 Blank applications and copies of regulations 

 and programs, sent by the legation, are filed 

 for reference in the Bureau of Foreign Com- 

 merce. 



UNIVERSITY AND EDUCATIONAL NEWS.

 Cornell University, who spoke on ' Problems 

 of Modern University Education as Suggested 

 by the Charter of the University of Colorado.' 

 The other addresses were given before the 

 professional schools. Dr. Frederic S. Lee, of 

 Columbia University, spoke on ' The Scientific 

 Aspect of Modern Medicine'; Mr. Frederick 

 N. Judson, of St. Louis, Mo., spoke on ' The 

 Quarter-Century in American Jurisprudence'; 

 and Professor Dugald P. Jackson, of .the Uni- 

 versity of Wisconsin, on ' The Potency of
