" How the Map of the Grand Canyon was 

 made." The maps of the Grand Canyon, 

 Tosemite Valley and the new Glacier National 

 Park have all been prepared by Mr. Matthes, 

 who is now engaged upon the map of the new 

 Mt. Eanier National Park. 



Samuel Calvin, professor and head of the 

 department of geology, State University of 

 Iowa, and state geologist of Iowa, died at 

 Iowa City on April 17. He was 71 years of 

 age and had been connected with the Univer- 

 sity of Iowa for thirty-seven years. 



Professor J. Bosscha, the Dutch physicist, 

 died on April 15, aged seventy-nine years. 



Dr. J. T. Thompson, the author of valuable 

 contributions to ophthalmology, died at Car- 

 difi on April 28. He was a brother of Pro- 

 fessor Sylvanus T. Thompson. 



The directors of the New York Public 

 Library announce a gift of $375,000 by Mr. 

 Andrew Carnegie to be used for establishing 

 and maintaining a library school. 



A BILL has been introduced into the legis- 

 lature of New Jersey providing for the ap- 

 pointment of a state plant pathologist. 



Dr. Charles A. Oliver, of Philadelphia, 

 has bequeathed his property valued at $16,000 

 to the Wills Eye Hospital, the University of 

 Pennsylvania and the College of Physicians 

 of Philadelphia. 



The Gray Herbarium, Harvard University, 

 is to have new quarters for its library. The 

 structure will be a two-story addition to the 

 present building and will extend to the west, 

 taking the place of the old library wing, and 

 covering part of the site recently occupied by 

 the Asa Gray House, which was removed 

 some weeks ago. The addition will be of 

 similar construction to the Kidder wing. 

 The library, which will be placed in the new 

 building, is devoted to the classification of 

 flowering plants and ferns. It contains more 

 than 20,000 volumes and pamphlets. The gift 

 which makes possible the erection of the new 

 building amounts to $25,000; it comes from 

 an anonymous friend of the university. 



The research committee of the National 



Geographic Society of Washington has made 

 an appropriation of $5,000 for continuing the 

 glacier studies of the two previous years in 

 Alaska. The work, beginning in June, 1911, 

 will be done by Professor E. S. Tarr, of Cor- 

 nell University, and Professor Lawrence Mar- 

 tin, of the University of Wisconsin, who have 

 directed the National Geographic Society's 

 Alaskan expeditions of 1909 and 1910 in the 

 Takutat Bay, Prince William Sound, and 

 lower Copper River regions. The 1911 expe- 

 dition will study briefly a number of regions 

 of glaciers not previously investigated by the 

 National Geographic Society, although par- 

 tially mapped by the Alaska Division of the 

 U. S. Geological Survey, the Boundary Com- 

 missions, etc. Work will be done on the pres- 

 ent ice tongues and the results of glaciation 

 in the mountains and plateaus of parts of the 

 interior and some of the fiords of southeastern 

 Alaska, the former having lighter rainfall and 

 smaller ice tongues than the Takutat Bay 

 and Prince William Sound regions. 



The Home correspondent of the London 

 Times calls attention to the fact that for some 

 time past Herr Immanuel Priedlander, of 

 Naples, has been working for the establishment 

 in that city of an International Institute to 

 carry on a continuous and systematic investi- 

 gation of volcanic phenomena. An observatory 

 has existed on Vesuvius for many years, but 

 from the insuiEcient means at its disposal no 

 extended and systematic work has hitherto 

 been possible. Such an institute as Herr 

 Friedlander contemplates will be provided with 

 the necessary laboratories and instruments for 

 the regular measurement of temperatures on 

 Vesuvius, for the periodical collection and 

 analysis of the gases, and for the registration 

 and observation of local earthquakes of a vol- 

 canic character, not only during the eruptive 

 phases of the volcano, but also throughout its 

 periods of comparative calm. It would form 

 a training school for volcanologists, as well as 

 give opportunity for other scientific persons to 

 make observations. Herr Friedlander's idea 

 is not a new one. An International Insti- 

 tute on Vesuvius was advocated some time ago 

 by Professor Johnston Lavis; Mr. Cool, a
