ern part of the west Kootanie district. Mr. J. B. Tyrrell conducted an 

 expedition through the "Barren Grounds," but owing to the short time 

 which elapsed between his return and the publication of the report, 

 only brief notes on the trip are given. A somewhat fuller account of 

 the expedition of 1893 is, however, inserted. Dr. R. Bell and Mr. W. 

 Mclnnes spent the season in Ontario on work previously begun. 

 Among other points. Dr. Bell determined that the gneissic area 

 between St. Mary's River and Gonlis Bay is not connected with the 

 granitic tract lying to the northeast, but forms an isolated mass. Dr. 

 R. W. Ells was engaged upon work along the Upper Ottawa and 

 adjacent regions. Some interesting points of structure were observed 

 at various places. While it is very evident that the syenites or granites, 

 as a whole, in this section are intrusive in the crystalline limestone, 

 some portions of them are of comparatively recent date. At one 

 point they have disturbed horizontal beds of Calciferous and Chazy, 

 and at another have penetrated and altered the Potsdam. Mr. A. P. 

 Low spent the seasons of 1893-4 in exploring the interior of Labrador 

 and his report, when it shall be completed, promises to correct the 

 popular notion that Labrador Peninsula is a waste, barren region 

 totally unfit for habitation. One of the important results of the 

 exploration is the discovery of a great tract of Cambrian rocks carrying 

 rich beds of iron ore. The strise of the region show that the icex)f the 

 glacial period flowed off in all directions from the central area. Mr. 

 R. Chalmers concludes as a result of the season's work that the facts 

 altogether demonstrate that Nova Scotia has been glaciated entirely by 

 ice which gathered upon its own surface, and afford no evidence of a 

 great ice-sheet crossing the Bay of Fundy and overriding that penin- 

 sula. Mr. Whiteaves reports that the second part of the third volume 

 of Palceozoic Fossils, consisting of a monograph upon the fossils of the 

 Guelph formation of Ontario, is completed and ready for publication. 

 The volume as a whole is well printed and well illustrated and 

 forms a most valuable addition to the literature of the region. The 

 area in which the Canadian Survey works is not only one of great 

 extent, but also of great complexity. It is furthermore to a consider- 

 able extent unsettled and unexplored. As a result, the cost of 

 geological investigation is relatively high. In view of these facts, and 

 the known wealth in mineral resources of much of the partially 

 explored country, it would seem that the director's plea for larger 

 appropriations is well founded. It is to be hoped that the government
