i^iometres '^^^ surface drift is consequently sandy in char- 

 acter, and true sections are not seen until 

 Manitou lake is reached. 



South of the track at Wainwright the 

 Canadian government has reserved nearly 

 144 square miles (37,762 hectares) for the 

 maintenance of a herd of 1,217 bison (1912) 

 commonly known as buffalo. The experiment 

 appears to be successful and the heid is increas- 

 ing; 220 calves are reported for 191 2. 

 618 m. Zumbro — Altitude 2,051 ft. (625 m.). 



994-4 km. Between Zumbro and Yonker the railway 

 follows the south shore of Manitou lake. The 

 cut banks seen in the distance consist of the 

 light coloured sands of the upper portion of 

 the Belly River series. The basin is part of a 

 former drainage channel into which several 

 minor channels converge. 

 585 m. Unity — Altitude 2,087 ft. (636 m.). From 



941 km. Vera to Unity the railway traverses an old 

 channel leading to Manitou lake, narrowing to 

 Unity, where the general prairie level is gained. 

 The plateau marks the approximate top of the 

 Belly River series, the terrace lying to the north 

 being probably underlain by Pierre shales. 

 From Unity the railway runs along the foot 

 of a slight escarpment which marks the 

 northern edge of the Belly River rocks, 

 that occasional cuts show to consist mostly of 

 yellow sands. 

 569 m. Scott — Altitude 2,159 ft. (660) m.). South 



915-5 km. of Scott an old drainage channel marks the 

 extreme end of the Eagle Hill creek drainage 

 basin. Eastwards between Reford and Cob- 

 lentz the cuttings show heavy deposits of boulder 

 clay. 

 535 m. Oban — Altitude 2,120 ft. (646 m.). Two 



861 km. miles (3-2 km.) west of Oban dark shales 

 outcrop and probably lie above the Belly 

 River. From Oban eastwards to Mead, the 

 country is rolling and constitutes the Eagle 

 Hill belt, possibly underlain by Tertiary rocks. 

 East of Mead the surface is very uniform and 

 is underlain by sandy shales which suggest a
