I. Notice of the Physical Characters of Rupert District, Red River, 

 Hudson Bay. Communicated by William Rhind, Esq. With 

 exhibition of Specimens, collected by Major George Seton. 



Eupert's Land forms the south-west portion of that vast 

 valley which surrounds Hudson Bay, North America. From 

 the north border of Minnesota, a territory of the United States, 

 and that slightly-elevated watershed where the head springs 

 of the Mississippi Eiver have their origin, the Eed River also 

 takes its rise, but flows north in a contrary direction to 

 the Mississippi, passes through the centre of Kupert's Land, 

 and terminates in Lake Winnipeg. From this river the 

 district extends north-west and south towards the Eocky 

 Mountains, with an area calculated at forty millions of acres. 

 The face of the country is level, with a slight slope towards 

 the north and east, the prevailing rock is a magnesian lime- 

 stone, with fossils, belonging to the Upper Silurian system, 

 of a white colour, sometimes of a chalky, and sometimes a 

 cherty structure, is a good building-stone, and affords lime 

 by burning, corresponding probably to the Landeilo strata of 

 England. The strata form a series of low terraces rising 

 iii the direction of the Eocky Mountains. Above the lime-
