nearly 6 miles, passing north through sections 23, 14, 11, and 2, Lintl, and 

 the southwest part of section 35, township 150, range 55. High portion 

 of the upper beach in the south edge of section 14, 1,153 feet, and depres- 

 sion west, 1,142 feet; crest onward through tins section, 1,153 to 1,149 feet. 

 In the north part of section 11 and the south edge of section 2 it is a few 

 feet lower, is irregular in height and outlines because of intersecting water- 

 courses, and has a less continuous and shallower depression on its west side. 

 In section 2, however, lioth beach ridges are finely displayed, having the 

 same contour as southward. Crest of upper beach in sections 2 and 35, 

 1,152 to 1,155 feet; depression on the west, 8 to 15 feet, partly occupied 

 by a long slough. The northwest part of section 35, in the course of these 

 beaches, is lower smooth till, with no deposits of sand and gravel. 



Goose River, near the north line of the northwest quarter of section 

 35, and the Little Groose River, in the north part of section 15, townsliip 

 150, range 55, where they cross the ancient lake shore, are in valleys about 

 30 feet deep, eroded in till. Each consists of pools 5 to 7 feet deep and 10 

 to 20 feet wide, alternating with other portions so narrow that one may step 

 across them. 



In the east part of the west half of section 2G and tlie southwest corner 

 of section 23, township 150, range 55, the ixpper Herman shore is oifset a 

 third of a mile east from the remainder of its course and consists of massive, 

 irreo-ular swells of till, partly overspread with gravel and sand, 1,152 to 

 1,160 feet. Among them are hollows 4 to 6 feet deep, without outlet, and 

 their entire belt, a, quarter of a mile wide, is crossed by depressions as low 

 as 1,145 feet. Through section 22 this shore bears a typical beach ridge of 

 sand and gravel, 40 to 50 rods wide, 1,157 feet, with depression of 10 to 15 

 feet on the west; descent of the eastern slope, 20 to 25 feet in 30 or 40 rods. 

 In section 15 this upper beach, 1,152 to 1,157 feet, has a quite irregular 

 form, chiefly due to erosion by the Little Goose River and its small tribu- 

 taries. It is again exhibited in its ordinary type through section 10, being 

 a ridge 25 or 30 rods wide, with crest at 1,155 to 1,157 feet, 15 to 20 feet 

 above its east base and with a narrow depression of 4 to 8 feet on the west; 

 through the west part of section 3, township 150, rauge 55, and the west edge 

 of the southwest quarter of section 34, township 151, range 55, 1,157 to
