799 



king of Belgium has accorded the congress his 

 patronage, while Prince Albert of Belgium 

 will be one of the honorary presidents, as also 

 will the ministers of finance, railways, war 

 and trade, and the mayor of Brussels. Among 

 the papers to be read will be one on the indus- 

 tries of Belgium, by Baron E. de Laveleve 

 and M. Camerman. 



The Maryland Geological Survey has estab- 

 lished a permanent State Mineral Exhibit in 

 the old House of Representatives at An- 

 napolis. The materials forming this exhibit 

 have been gradually collected by the survey 

 during the last few years, the nucleus being 

 the Maryland mineral exhibit at Buffalo in 

 1901. This was materially added to in the 

 preparation of the state's exhibit at Charleston 

 the following winter and was still further in- 

 creased for the Maryland exhibit for the 

 Louisiana Purchase Exposition at St. Louis 

 in 1904. The latter display has again been 

 much enlarged for the present purpose and is 

 intended to thoroughly illustrate the mineral 

 resources and industries of the state. The 

 exhibit was opened the first of April at the 

 time of the session of the legislature. 



The atlas published by the U. S. Geological 

 Survey to accompany Monograph 32 on the 

 Geology of the Yellowstone National Park is 

 now available. Bound in paper the atlas 

 costs $2.80, in cloth $3.75, in sheepskin $4.25. 

 Whether his taste in bindings inclines by na- 

 ture to the esthetic or by necessity to the 

 utilitarian, the scientist may now have maps 

 of the Yellowstone. The monograph, which 

 the atlas is destined to accompany, is several 

 years older, but costs less. It first saw the 

 light in 1899, and it sells for $2.45. Only the 

 second volume, however, is published. Dr. 

 Arnold Hague and his assistants had previ- 

 ously brought out, in 1896, a geologic folio 

 relating to the Yellowstone National Park, 

 which has the distinction of being the only 

 geologic folio that ever sold for 75 cents. The 

 atlas contains six topographic maps, which 

 cover the area of the Yellowstone National 

 Park and a large portion of the Yellowstone 

 Forest Eeserve. The Yellowstone National 

 Park is situated in the northwest corner of 



the state of Wyoming, but a narrow strip, 

 about two miles in width, along the west side 

 extends into Montana and Idaho, and the 

 northern boundary lies in Montana, two miles 

 north of the Wyoming state line. The scale 

 of these sheets is nearly two miles to the inch. 

 A combined map of the six large topographic 

 sheets is also published as one double-page 

 map. Six geologic maps of the same areas 

 covered by the topographic work are included 

 in the atlas. The six geologic sheets are also 

 combined to form a double-page map, which 

 shows the areal geology of the Yellowstone 

 National Park and a portion of the Yellow- 

 stone Forest Eeserve. In the reserve is in- 

 cluded the greater part of the Absaroka 

 Range, a feature essential to the correct un- 

 derstanding of the geology of the park. Ta 

 the tourist this atlas will make a special ap- 

 peal, as it makes available for the first time 

 reliable maps of the various geyser basins in 

 the park. The fact that these interesting 

 natural phenomena have been mapped will 

 have a tendency to reduce the number of 

 names indiscriminately and confusingly ap- 

 plied to them by guides, visitors and students, 

 and to secure the general adoption of the 

 place names used on the maps. The corps of 

 assistants that aided Dr. Hague in the inter- 

 pretation of this great area included Messrs. 

 Joseph Paxson Iddings, Walter Harvey Weed,. 

 George M. Wright and T. A. Jaggar, Jr. 



We learn from the London Times that a 

 resolution has been adopted by the council of 

 the Royal Scottish Geographical Society and 

 ordered to be submitted to the Secretary of 

 State for India in Council. It is to the effect 

 that, in view of the great regret felt in geo- 

 graphical circles throughout the world that 

 the proposed expedition down the Brahma- 

 putra to Assam did not take place at the close 

 of the Tibet mission, 1903-4, the council trust 

 that the Indian government will now see their 

 way to carrying out this exploration, which is 

 of extreme interest and importance, on the 

 following grounds: By it would be finally 

 settled the question of the connection of the 

 Sang-po of Tibet with the Dibong (Brahma- 

 putra) of Assam. The known difference of
