HERMAN BEACHES NEAR TREHERNB. 367 



tract of mitrainic drift which overspreads the east part of the Tiger Hills, 

 as crossed in township 7, range 9, by the road to the south from Treherne. 

 About 20 and 50 rods north of the beach just described two inconspicuous 

 beach lines, terrace-like sand and gravel deposits, are found at 1,266 and 

 1,254 feet, referable to subdivisions (&^ and hh) of the second Herman 

 stage. A little farther north tlie third Herman beach is represented at 

 Irvine Scarrow's house, in the south edge of section 6, township 8, range 9. 

 This is a slight terrace with crest at 1,243 and 1,244 feet and descent of 

 4 or 5 feet on its north side. Mr. Scarrow's well, on this beach, 31 feet 

 deep, consists of black soil, 2 feet; interbedded sand and clay, 10 feet; 

 very coarse shale gravel, 5 feet ; beds of coarse and fine gravel and sand, 

 13 feet; and very hard dark bluish till at the bottom, dug into onlj^ 1 foot. 

 This well shows an accumulation of shore drift to a depth of 30 feet, 

 swept out by the currents of the lake from the curve where its beaches 

 turned westward. About an eighth of a mile north of Mr. Scarrow's house 

 another beach, also referable to the third Herman stage, descends from 

 1,236 and 1,238 feet at its crest to 1,230 feet at the base of its northward 

 slope. At the summit of the Manitoba and Southwestern Railway, a mile 

 east of the Little Boyne River, and on the slope thence eastward, very 

 massive beach deposits are accumulated, due apparently to the same 

 action of northwestward currents from the northern end of the Pembina 

 Moimtain. The summit of the railway is on such a beach, 1,217 to 1,220 

 feet above the sea, the fourth in the Herman series, forming a broad swell 

 from which a gentle slope falls on its northeast and southwest sides. Ai'thur 

 Willett's well here goes to a depth of 42 feet in beds of sand and gravel, 

 obtaining a plentiful supply of good water from their lower portion, with- 

 out reaching their bottom. A fifth of a mile farther east the railway cuts a 

 beach ridge with its crest at 1,211 feet, also referable to the fourth Herman 

 stage. 



The Assiniboine delta occupies the western border of Lake Agassiz 

 from Treherne westward about 60 miles to Brandon, and thence north- 

 eastward about 35 miles to Neepawa. The shore of the lake along these 

 distances is not generally marked by a definite beach ridge, the absence of 

 which seems to be accounted for chiefly by the extreme shallowness of the
