634 General Notes. [J u b'» 



bay much of the land is good ; to the south-west the country is 

 well wooded, and valuable minerals, including iron-stone, galena, 

 gypsum, petroleum-bearing limestone, etc, are known to exist. 

 The land around Hudson's bay is rising from five to ten feet in a 

 century. It is not improbable that, possessing a sea-port in the 

 very center of the continent, 1500 miles nearer than Quebec to 

 the fertile lands of the Northwest territories, Hudson's bay may 

 prove the future highway between those territories and Europe. 



This portion of the report concludes with a memoir upon the 

 northern limits of the principal forest trees of Canada; a list of 

 thirty-eight species of fossils collected in Manitoba, principally 

 coelenterates, brachiopods and gasteropods; a list of 261 species of 

 plants collected at various spots around Hudson's bay in 1880, 

 and a catalogue, by Dr. J. L. LeConte, of the coleoptera collected 

 between Lake Winnipeg and Hudson's bay. Other appendices 

 are devoted to the mollusca, the analysis of the waters of Hayes' 

 and Nelson rivers, and weather statistics. 



The Magdalen islands are thirteen small islands in the Gulf of 

 St. Lawrence, inhabited principally by French Acadians, and 

 capable of becoming an unrivaled sea-side resort on account of 

 the clean sandy beach backed by rich greensward. 



Absence of Ancient Glaciers in Eastern Asia.— In an 

 article on glaciers and glacial periods in their relations to climate, 

 in Nature, A. Woeikof refers to the fact that the great interior 

 plateaux of Central Asia are too dry for glaciers. China, Mand- 

 chooria and Amoor are destitute of glaciers owing to the want of 

 moisture in the winter time, dry north-west winds then prevail- 

 ing. This has been the case since the Pliocene period. Purn- 

 pelly and Richthofen found no traces of ancient glaciers in China 

 nor on its western and northern borders, neither did Dr. Schmidt 

 find any in the Amoor. As to the plateaux of Central Asia, they 

 must have been exceedingly dry since the rise of the Himalaya 

 and Karakoram to the south and the Pamir heights to the west 

 of them, and thus have had nothing corresponding to the later 

 glacial periods of Europe and North America.
