the general location of this strip within which lie the sediments 

 whose correlation is dealt with in this paper. The Tirniskaming 

 Northern Ontario Railway passes through its western end, 

 affording access to the important mining center of Kirkland Lake 

 through Swastika station, and to Larder Lake through Dane sta- 

 tion. The only access to the Quebec portion of the area is by 

 canoe from Lake Timiskaming, Larder Lake, or the National 

 Transcontinental Railway. 



PREVIOUS WORK AND CONCLUSIONS 



Reconnaissances along easily accessible water routes were 

 made as early as 1900 by W. J. Wilson,^ W. G. Miller,^ L. L. Bolton, ^ 

 Walter McOuat,^ W. A. Parks,^ J. Obalski,^ and J. F. E. Johnston,^ 

 but the first detailed work appears to have been that of Brock^ 

 and Bowen,^ in 1908, at Larder Lake. In the four years following 

 the whole of the krea shown in Figure i was mapped in more or less 

 detail by A. G. Burrows, and P. E. Hopkins,'" E. L. Bruce," M. E. 

 Wilson,'' R. Harvie,'^ and J. A. Bancroft.'^ 



These writers have reached very different conclusions regarding 

 the age and external relations of the sediments in this strip of ter- 

 ritory. Burrows and Hopkins (191 2) consider the sediments of 

 Teck, Lebel, and Gauthier townships to be a single series of inter-
