the base the Assiniboine beds, 168 feet — a total thickness of 556 feet. 

 The position of the series is determined by levelling at the Assiniboine 

 river where the top of the Assiniboine beds is placed at 964 feet above 

 sea. The division in the Pierre seems to be quite uncertain in the 

 vicinity of the Pembina escarpment. The recognition of the weathered 

 shales as Millwood or Odanah is not satisfactory, as in the south 

 the Millwood seems to have included in it hard layers that have been 

 mistaken for Odanah, so that the division as given in the Deloraine 

 well is adopted. The positions of coal seams in Turtle Mountain 

 and the Boissevain sandstone depend on levelling observations made 

 by the writer and published on a map of Turtle Mountain included in 

 the Summary Report of 1902. The coal seam near Redvers is reported 

 in local news items as eight feet of coal at a depth of 250 feet, and at 

 Wauchope a six foot seam at 150 feet depth. At Carrievale a small 

 seam of coal is reported at a depth of 231 feet. These are projected 

 from the elevations of the surface in the vicinity of the wells. At 

 Oxbow, several seams were penetrated, but of these there is no accurate 

 record. The Taylorton borehole is here represented by the composite 

 section given by Mr. MacLean in Summary Report 1918, Part A, p. 4. 

 The lower seam is placed at 623 feet below the surface according to a 

 statement in Summary Report, 1917, Part C, p. 40. The record of the 

 Ralph well is given in Mémoire No. 116, p. 45. 



In these sections the position of the various coal seams above 

 the Niobrara is fairly accurate, so that the correlations of the Redvers 

 seam with the lowest at Taylorton, and the Wauchope seam with the 

 one above, seem reasonable. Their correlation with the seams in 

 Turtle Mountain, while not absolute, being dependent on the record 

 of the Fleming well, suggests that there may be several undiscovered 

 seams in the upper part of that mountain, and would mean a further 

 possibility for a coal supply in the Province of Manitoba. 



As there are no exposures from which fossils might be obtained 

 the position of these lignite beds has been assigned to the beds associ- 

 ated with the Tertiary rocks of Estevan. The projection on the 

 section submitted shows that they lie below the exposed Tertiary 

 beds, and are those explored by the drill at Taylorton. Their relation 

 to those of the Lance formations in Dakota is not definite, but they 

 appear to occupy the same relative position as the Ludlow lignitic mem- 

 ber. Lender Taylorton the drill records do not mention light coloured 

 material, generally grey coloured sands and clays. In the eastern or 

 Turtle Mountain section all the material exposed is yellowish and 

 lighter in colour, so that in Canada there is a colour change in the beds 

 which appear to be Ludlow. This may be an argument for the correl-
