HERMAN BEACHES IN BRANDON. 369 



of 10 feet of oblicjuely l)edded sand and gravel, coiitaiiiing' abuiitlaut peb- 

 bles up to 2 iuclies and rarely cobbles 3 or 4 inches in diameter, about 

 two-thii'ds being- Paleozoic magnesian limestones, from oue-tentli to one- 

 fourth Cretaceous shale, and the remainder mostly Archean granites and 

 schists. This beach ridge varies from 10 to 20 rods in width and from 5 

 to 10 feet or more in height, having a smoothly rounded, wave-like form. 

 The elevation of its crest near tli<? court-house ranges from 1,260 to 1,269 

 feet above the sea, and at Eleventh and Twelfth streets it is 1,260 to 

 1,261 feet. No distinct beach ridge of the slightly higher Herman h stage 

 of Lake Agassiz was found in the vicinity of Brandon, but evidence of the 

 lake level in that stage is afforded in the southeast part of Brandon by 

 the delta plateau of coarse gravel and sand at the com't-house and east- 

 ward, which is 1,270 to 1,282 feet above the sea, and by an old water- 

 course crossed 3 to 4 miles west of Brandon on the road to Kemnay, both 

 of which are more fully noticed in the description of the Assiniboine delta. 

 North of the Assiniboine the highest shore of Lake Agassiz passes 

 from Brandon east and east-northeast by Chater and Douglas, being on or 

 close below the verge of the plateau of till, overspread by delta gravel and 

 sand, which lies close north of the Canadian Pacific Railway. About a 

 mile north of Douglas station this shore is marked by a dune hillock, nearly 

 at the middle of the line oetween sections 10 and 11, township 11, range 17. 

 Thence its course is north-northeastward, and is indicated by an eroded 

 escarpment, extending 2 or 3 miles, with a height of 10 to 15 feet, and less 

 distinctly observable a few miles beyond. The base of this escarpment 

 where it crosses the south line of section 24 in this township is 1,269 feet 

 above the sea; and the surface at the schoolhouse, a sixth of a mile farther 

 west, is about 20 feet higher. All the area eastward is delta sand and 

 gravel; but the escarpment and the country rising thence slowly noilh- 

 westward ai-e till. The continuation of this line between a moderately 

 rolling sm-face of till on the west, with plentiful bowlders and frequent 

 lakelets, and the slightly undulating sand and gravel delta on the east, with 

 low dunes on many parts of its area, passes north-northeastei'ly in range 16 

 across the west half of township 12 and the east half of township 13, and 

 thence north through the eastmost tier of sections in townsliip 14, to Stony
