Township, where it is about one-fourth of a mile wide. In places it has 
a width of about one-half of a mile. Near the east end as it approaches — 
the river a large area of muck occurs. This channel seems to enter the 
Wabash Valley in the western edge of Section 36. Another deep valley 
enters the Wabash Channel in the eastern half of Section 31, heading 
toward the southeast. It starts just north of the present State insane 
institution at Long Cliff. Near the western end this valley has almost 
perpendicular walls and a width of over one-fourth mile. The southern 
escarpment of the two channels in Clinton Township, taken as a whole, 
show a very irregular outline with numerous gullies and V-shaped val- 
leys, indicating very extensive erosion, while on the opposite side no 
indication of stream erosion exists. At present it is occupied by a few 
small streams, but no large ones. 
Early History.—Until 1824 Cass County was included in Tippecanoe 
County. The organization of the county was completed April 13, 1829, 
under acts of the State legislature, passed December 18, 1828, and 
January 19, 1829. At that time it contained all that portion of the 
State now included in the counties of Miami, Wabash, Fulton, Marshall, 
Kosciusko and St. Joseph and parts of Laporte, Starke and Pulaski. 
The county seat was located at Logansport, August 10, 1829. 
The first owners of the soil of Cass County were the Pottawottomie 
and Miami Indians. The former owned the land north of the Wabash, 
and the latter that upon the south. The first cessions of lands was 
made by the Miamis in the treaty of 1818, in which they gave up the 
land west of the mouth of Eel River. The Pottawottomies surrendered 
the land north of the Wabash in 1876 at the Mississinewa treaty and at 
subsequent times and by various other treaties. 
Logansport was named in honor of Captain Logan, a Shawnee chief, 
who lost his life in November, 1812, because of his fidelity to the whites, 
and not for Logan the Mingo, as many suppose. The original plot of 
the town contained 111 lots, with streets 66 feet wide, except Broadway, 
which is 82% feet wide. 
Roads.—December 31, 1918, Cass County had 452% miles of free 
gravel roads and 340 miles of unimproved roads. Rural free delivery 
extends to all parts of the county, which stimulates the extension of 
good roads.

Federal Census, including estimated population for 1920:
