international boundary. Both the narrow and the wide morainic belts 

 mentioned trend mainly from southeast to northwest, and were apparently 

 accumulated on the southwestern border of the ice-sheet during slight 

 pauses of its retreat, perhaps being all contemporaneous with the single 

 broad and massive Itasca moraine in northern Minnesota. 



The outermost of these belts, varying from a half mile to 1 mile or 

 more in width, here and there marked by hills 50 to 100 feet high, but 

 more commonly by lower and often very scanty knolls and swells, passes 

 from east to west about 3 miles north of tlie citv of Devils Lake, by the 

 south end of Dry Lake, through the northeast part of township 154, range 

 66, and thence by a somewhat devious course through the center of town- 

 ship 155, range 67 (there being on the west side of a chain of lakes which 

 occupies mitilled portions of the preglacial or interglacial channel of the 

 Mauvaise Coulee), and through the south half of township 156, range 68, 

 to the southwest side of Hurricane Lake, from which it runs westward, 

 becoming merged with the Leaf Hills moraine in the large morainic tract 

 north of Broken Bone Lake. The farther course of this belt forms a 

 south-to-north series of ch'ift hills on the west shore of Long Lake, and it 

 is doubtless traceable thence northward to the Turtle Mountain. Probably 

 also one or more of the wide belts of rolling and hilly di'ift observed north- 

 east and north of Devils Lake continue westerly to the east part of this 

 massive highland, contributing- to its morainic di'ift covering; but only 

 scanty morainic hillocks were sefen in the vicinity of Rolla and, indeed, 

 along the whole eastern and southern base of the mountain area. 



The continuation of the Itasca moraine in southwestern ilauitoba 

 extends northerly from the east end of Turtle Mountain, by Killamey, to 

 the northern part of Pelican Lake, a distance of about 25 miles. Thence 

 it extends west-northwest 20 miles, forming the west part of the Tiger 

 Hills in their extent along the north side of Langs Valley and the Souris 

 to township 7, range 19, where it again bends to the north and holds that 

 course 10 or 12 miles to the prominent Brandon Hills. Here again it turns 

 to the west, making a sharp angle, but within a few miles it sinks to the 

 general level of the adjoining country and loses its distinctive character. 

 Proceeding onward to the west about 20 miles, this moraine is next found
