British Columbia may be said to possess the 

 largest compact timber resources iu the "world. 

 Only the fringe has been cut. It is estimated 

 that the Douglass pine, cedar, spruce, Alaska 

 pine, etc., standing in the railway belt, amount 

 to 25,000,000,000 feet, worth $25,000,000. The 

 coast is heavily timbered as far north as Alaska. 

 There is no white pine, but spruce attains per- 

 fection in this section.

AN EXHIBITION OF GEOGBAPHIOAL AND 

 GEOLOGICAL MATERIAL. 

 The City Library Association of Springfield, 

 Mass., has recently erected a fine building, 

 which is to be devoted to the display and use of 

 collections in Natural History. As some inter- 

 val of time must elapse before the collections 

 ■can be installed, there has been arranged in the 

 main museum hall — 123x47 feet in dimen- 

 .sions-^an attractive and instructive exhibition 



of material which illustrates the rapid advance 

 in geography and geology. 



A study of this collection of maps and publi- 

 cations reveals great activity on the part of gov- 

 ernment and publishers in map-making and in 

 the adaptation of recent discoveries for the use 

 of school and colleges. An opportunity is of- 

 fered to compare the technique and scope of the 

 surveys and maps made by the United States, 

 England, France and Germany. There are 

 displayed a number of sheets of the Ordnance 

 Survey of England and many staflf maps from 

 Germany and France. The clearness with which 

 a multitude of details is shown on these pro- 

 ductions is remarkable. Then the results of 

 the topographical survey of the United States 

 are shown in a carefully selected series of atlas 

 sheets. The geographers of this country have 

 taken up with much zeal the task of classifying 

 various land forms. That such a proceeding is 

 hedged round with difficulties is easily ap- 

 parent. The best success has been had where 

 the relative development of a region has been 

 made the test in classification. Among the 

 sheets on exhibition are several selected by 

 Henry Gannett, chief geographer of the United 

 States. Use has also been made of the recent 

 work of Professor W. M. Davis, of Harvard 

 University. 



There is in the exhibition material which 

 illustrates recent progress in geology. The ex- 

 hibit made by the United States Geological 

 Survey at Omaha has been loaned for the pur- 

 poses of this exhibition. There are also exam- 

 ples of the work of the Geological Surveys of 

 Great Britain, of Canada, of Germany and of 

 many of the State governments. Especially 

 fine work has been done in New Jersey under 

 the direction of John C. Smock, and in Mary- 

 land by William Bullock Clarke. Professor B. 

 K. Emerson, of Amherst College, has loaned 

 his valuable manuscript maps on the geology of 

 old Hampshire county, in Massachusetts. 



There is also a very complete exhibition of 

 the works of the best map makers in this 

 country and abroad, and a number of relief 

 maps. The Association cordially invites all 

 persons interested in geography and geology to 

 to visit the exhibition, which it is now planned 

 to continue until July 1st.
