Much of the northern country remains unorganized 

 and the vast North West Territory (2,665,000 square 

 miles) between Hudson's Bay and the Rocky Moun- 

 tains, as well as Labrador, are for the most part unin-

The central interior region, dotted with lakes and 

 intricate river systems, is a continuation of the forest- 

 less, arid and subarid, plains and prairies of the country 

 West of the Mississippi River, toward the north

 with low hills, not over 1500 feet elevation, which cuts 

 it off from the northern country and forms the limit of 

 commercial forest. This region, the bulk of the 

 provinces of Ontario and Quebec a belt of not ex- 

 ceeding 300 miles in width and about 1500 miles in 

 length, altogether 300,000 square miles with 93,000
