Northern Sections, 
The water courses which correspond with the heads of the Big 
Beaver, and fall into Lake Erie, are from west to east; Grand River, 
Ashtahula, and Conneaut Creek of the Lakes. 
Grand River has dug for itself a bed, whose bottom is considera- 
bly lower than the general surface of the country to its east. At 
Bloomtield it is already 92 feet below the level of the turnpike. Its 
valley is deep, and its banks are very rugged, and formed of clay, 
without any tenacity. It offers some flats at the bends of the river, but 
in the intervals the banks are often perpendicular, on a height of 100 
or 150 feet. At its lowest stage it has but little water — its tribu- 
taries on the right bank are almost dried up in Summer, but on the 
left bank, descending from a higher country, they are more permanent. 
AVIien it reaches the natural dyke which bordeis on the Lake, Grand 
River, near Austinburg, runs suddenly to the west to Join Lake Erie, 
at Fairport. Its greatest floods rise from 15 to 16 feet; in the lower 
part of its course they do not rise above 8 or 10 feet, and at its mouth 
are insignificant. By sinking two rows of piles in continuation of 
that mouth, a passage has been opened for the river through a sand- 
bar, which formerly obstructed it, and on which there was only 10 or 
12 inches of water. But the piles are not closed, and an interval of 
1 or I2 feet has been left between them; it would be proper to sink 
more piles in these intervals, especially to the W. as the reigning 
winds are from the S.W. and the neighborhood is subject to squalls 
from the N.W. This would secure an important port on this part 
of the Lake. The bottom is sand and gravel, the length of the passage 
between the piles is from 270 to 330 yards, its breadth 1 38 yards. A 
new bar is formed at the mouth of the channel, but has 8 or 10 feet 
above it. 
The Aslitabula offers precisely the same feature as Grand River, 
as to tiie deplh of its valley, below tlie general surface of the country, 
and the rugged and perpendicular cliavacter of its banks. Conneaut 
creek of the Lakes offers the same features, and, as well as Grand River, 
has but a small provision of v/ater in the summer months, at least if 
compared totl)e Big Beaver, or Cuyahoga.
