des Noquets, and the valleys of the Menomonee and Manistee. The 
coarse drift described as occurring beneath the drift proper, at several 
points along the shore of Lake Superior, seems to be entirely wanting 
in this district. 
Starting from Mackinac westward, the furrows and striz were 
noticed at the bottom of St. Martins bay, and two miles north of Pine 
river, on a point composed of almost horizontal ledges of limestone, 
having an average direction from E. to W., some running N. 80° E,, 
and others 8. 70° and 80° E. At Payment point the direction being 
from N. 50° to N. 60° E, At the bottom of Big Bay des Noquets, on 
the west shore of the eastern cove, the direction is EK. and W. At the 
~ mouth of the Escanaba, in Little Bay des Noauets, the direction is N. 
E.and 8. W. At Oak Orchard, on the west shore of Green bay, the 
direction is N. 15° to N. 20° E. At the saw mill, near the mouth of 
the Menomonee, the direction is EK. and W.; six miles above Kitson’s 
trading house, E. N. E. and W.S. W.; three miles above Sturgeon’s 
falls, N. 65° E.; foot of the Lower Bukuenesec falls, N. 70° E.; Lower 
Twin falls, N. 60° to N. 70° E.; and at Upper Twin falls, N. 65° to 70° 
EK. From Green bay, southwestward, they were noticed at Mehoggan 
point, N. E. by E. and N. N. E.; at Mehoggan falls, N. E. by N.; three 
miles west of Milwaukee, N. E.; and at Strong’s landing on Fox river, 
N. E. by E. 
The true drift seldom approaches the shores of Lake Michigan and 
Green bay, but it is met with in ascending the rivers at no great dis- 
tance. Its absence from the coast is the result of subsequent denuda- 
tion, when the waters of the lake stood at a higher level than at present. 
It was observed at Pointe aux Chenes, and for a distance of six miles 
toward Payment point, and on Potawatomee and some of the higher 
islands. The thickness at Green bay was found on boring to be 108 
feet. 
Near the junction of the Machigamig and Brule, where the united 
streams take the name of Menomonee, the river banks are composed of 
drift, forming bluffs 100 feet or more in height. The drift is com- 
posed of sand and layers of gravel more or less interspersed through it, 
and covered more or less with bowlders. The higher lands adjoining 
are covered with the same materials. The country adjacent to the 
Manistee is likewise covered with the drift sand and pebbles. The 
whole country drained by the White-fish and its branches, and the 
Escanaba is likewise covered with the drift. The drift clay is well 
marked, in many places, below the drift sand, especially upon the
