east quarter of section 26, 1,165 to 1,166 feet; and at the quarter-section 

 stake on the north side of this section 26, 1,163 feet. 



Near the west line of section 23, Lampton, two Herman beaches abut 

 upon the east flank of the north end of "the mountains," and extend thence 

 north-northwesterly 2 miles to the Middle Branch of Park River. The 

 eastern one, a well-defined ridge of sand and fine gravel, passes close west 

 of the quarter-section stake between sections 15 and 10. The elevation of 

 .its crest is 1,161 to 1,166 feet, with increase in height from south to north; 

 the descent on the east is 15 or 20 feet in as manj- rods, and the depression 

 on the west is 3 to 8 feet deep and 10 rods wide. The other beach ridge is 

 40 or 50 rods farther west, parallel with the preceding and similar in form 

 and material; its crest, rising slightly northward, is at 1,173 to 1,176 feet. 

 Another distinct beach ridge, but of smaller size, runs in a parallel course 

 through the east part of the southwest quarter of section 9, with its crest 

 at 1,185 to 1,187 feet. These appear to represent together the thnd and 

 second Herman beaches of the series observed northwest of Maple Lake in 

 Minnesota and east and west of Larimore. The lowest Herman beach 

 in this vicinity passes as a well-marked ridge of gravel and sand tlirough 

 the west part of sections 11 and 2, Lampton, and the east part of sections 

 34, 27, and 22, Grardar, having a height of 1,145 to 1,150 feet, from which 

 there is a descent of 5 to 10 feet on the east and half as much on the west. 

 Upper Herman beach, northward from the north end of "the moun- 

 tains," forming in the northwest quarter of section 21 and the west part of 

 section 1(), Lampton, a massive broad ridge, composed of sand and gravel, 

 with pebbles up to 4 or even 6 inches in diameter, crest, 1,197 to 1,207 

 feet, rising highest northward, where the beach deposit overlies the eastern 

 slope of a wave-like swell of till that rises to 1,212 feet. Small beach 

 i-ido-e belono-ing to this stage, in the east edge of the southeast quarter of 

 section 8, Lampton, 1,202 to 1,207 feet. Surface at Evan Edwards's house, 

 in the west part of the southwest quarter of section 9, 1,197 feet, consisting 

 of sand and gravel of this beach to a depth of 10 feet, underlain by till, 

 yellowish in its first 6 feet and dark-bluish below. Summit of a smoothly 

 rounded hillock, probably till, but having few or no bowlders, in the east 

 edge of the northeast quarter of section 8, about 1,230 feet; train of beach
