The Great Plains 



Little has been added to the excellent work of Tyrrell and Dow- 

 ling on the Palaeozoic of the Manitoba Lakes region. In 1912 E. M. 

 Kindle reviewed the geology, gave faunal lists, and separated the lowest 

 Devonian as a basal division with the name "Elm Point Limestone." 

 In the far north the palaeozoics have received more consideration on 

 account of the recent developments in search of oil. A more detailed 

 classification and a wealth of fossil evidence are being prepared for 

 publication at the present time. 



A. E. Cameron in 1916 and 1917 gave the following classification 

 of the rocks of the Great Slave Lake district :—
