In 191 9 I studied the formations of the Glacier Lake District at the 

 headwaters of the Saskatchewan River, and during the field season 

 of 1920 the Devonian and pre-Devonian formations at the head of 

 Clearwater River and Pipestone Pass, about t,^ miles (53.1 km.) 

 east-southeast of Glacier Lake section. In 1924 I proposed the name 

 Messines for the Middle Devonian limestone at Glacier Lake, where 

 it is superjacent to the Ordovician (Canadian) Sarbach formation.' 

 The Messines appear to be the equivalent of the Intermediate lime- 

 stone of McConnell. The name Pipestone was proposed for the 

 Upper Devonian limestone at Pipestone Pass, which is about 33 miles 



(53.1 km.) east-southeast of Glacier Lake, and 42 miles (67.6 km.) 

 north of the south end of the Sawback Range, where McConnell 

 studied his Banff limestone series. The Pipestone limestone is pre- 

 sumably the stratigraphic equivalent of the Lower Banfif limestone 

 of McConnell. 



Dr. E. M. Kindle published the results of his study of the Devonian 

 section of the south end of the Sawback Range in 1924.^ He found 

 that the Upper Banfif shale of McConnell contained a Triassic fauna 

 and proposed the name Spray River formation for it. For the 

 Upper Banfif limestone the name Rundle Mountain was proposed, 

 and the Lower Banfif shale was shortened to Banfif shale. The Lower
