the northwestern shores of Hudson bay and in the southern part 

 of Baffin island, by the rounded and polished rock surfaces, 

 which are everywhere well marked by the ice striae, often in 

 several sets showing- changes in the direction of the ice move- 

 ment. On the east side of Baffin the rock surfaces show signs of 

 rounding and smoothing by ice, but the striae are not well 

 marked, and the glaciation does not appear to have been nearly 

 so intense as to the south and westward. Passing northward up 

 the western side of Davis strait and Baffin bay, the evidence of 

 intense glaciation becomes less and less, that on Ellesmere the 

 present condition of the local ice-covering would appear to repre- 

 sent nearly as great an amount of glaciation as ever occurred 

 there." 



3. Geological Survey of Brazil. — A Geological Survey of 

 Brazil has recently been established and placed under the charge 

 of Dr. Oryille A. Derby, well known for his valuable con- 

 tributions to the geology and mineralogy of the country. This 

 important enterprise is due immediately to the wise foresight of the 

 new President, Dr. Affonso Augusto Moreira Penna, inaugurated 

 on the 15th of November last, and Dr. Miguel Colman du Pine 

 Almeida, appointed by the President to the portfolio of Indus- 

 try, Highways and Public Works. Dr. Colman was formerly 

 Secretary of Agriculture of the state of Bahia, where he proved 

 himself one of the most able and far-sighted of the younger gen- 

 eration of Brazilian engineers and administrators. The new 

 department, denominated Servipo Geologico e Mineralogico do 

 Brazil, will be located in Rio de Janeiro. The leading feature 

 of its program is the rapid reconnaissance of the general geology 

 of the country with detailed investigation of the districts, that on 

 account of their mineral wealth, deficiencies of water supply or 

 other reasons, offer special scientific and economic interest for 

 investigation. Owing to the lack of proper topographic maps no 

 systematic map work will for the present be attempted. 



Dr. Derby is remarkabty well fitted for the post to which he 

 has been appointed, since he has been active in scientific work in 

 Brazil for many years and is well acquainted with all the local 

 conditions. He organized and long directed the geographical 

 and geological survey of the state of Sao Paulo. Dr. Derby, it is 

 stated, will be assisted by such native and foreign resident geolo- 

 gists as have made valuable contributions to the geology of Brazil.
