North shore of Lake Athabasca. 



Dubawnt River, just below Daly Lake. 



This species occurs in scattered groves down the Dubawnt 

 River to Dubawnt Lake. On the shore of Hudson Bay it 

 reaches its northern limit at the mouth of Nelson River. 

 The most northern examples are spreading shrubs in the 

 middle of which may be found a small upright stem four 

 or five feet high. — J. B. T. 



154. Picea alia. Link. — W.B. 



North shore of Lake Athabasca. 



The sandy eskers near Hinde and Boyd lakes were thinly 

 covered with fine large trees of this spe'cies. Groves of 

 large trees were also growing on the wet but well drained 

 flats or slopes beside the Dubawnt River down to within a 

 short distance of Dubawnt Lake. Many large drifted trunks 

 were also found at the forks below this lake. Its northern 

 limit on the shore of Hudson Bay is at Little Seal River, 

 north of Port Churchill, where it replaces the preceding 

 species in the wet swamps near the shore. — J. B. T.
