State from the Mississippi River to the western State boundary. Lillard county 
extended from the Missouri River to Grand River, and Saline bounded it on the 
east. Saline and Cooper extended from the Missouri to the Osage. Wayne 
county included a fourth part of south Missouri, extending from Washington to 
the west State line. 
On this map Pike County included all of Illinois west of the Illinois River, 
and on the north reached across to Indiana. There were twenty-six counties in 
Illinois, and Ft. Dearborn was on Lake Michigan where now is the city of 
Chicago. 
In Schoolcraft's Travels, through certain portions of the Mississippi Valley, 
1 821, we find a small map of the Ohio Valley with Illinois, Michigan and Eastern 
Missouri. On this map we find laid down on the north side of the Ohio, from 
opposite the mouth of White River (of the Wabash) to opposite the mouth of 
Tennessee River, the Oshawana (Shawnee) mountains. From Chicago to St. 
Louis and near the Illinois River, we find Mt. Johet, Rock Fort, Ft. Clark, and 
Mauvais Terre. In this volume there is also a small geological sketch map of 
the Lead District of Eastern Missouri, extending from the Missouri River to 
beyond Fredericktown. This map is printed with south at top, and north at 
bottom. 
On Mitchell's Map of Missouri, 1835, we find that there were then thirty- 
two counties in Missouri, and Green county joined Gasconade and Crawford on 
the east, with Pulaski on the south, while west of these the State seemed yet 
not to be divided into counties. Jackson and Lafayette extended to Grand 
River on the south and Pettis reached to the Osage. The Platte Purchase was 
not yet made and Clinton extended from Clay to the north line of the State. 
Chariton also extended from the Missouri River to the northern boundary, and 
Missouri was bounded by Wisconsin Territory on the north. From Potosi 
westward to the Gasconade River we find the "Black Hills." The Ozark Moun- 
tains extended from northwest Arkansas northeastwardly to central South 
Missouri. 
On Morse's Map of the United States, 1844, the south and west boundary of 
the United States is : beginning at the south, the Sabine River and west boun- 
dary of Louisiana to Red River, thence up Red River to a little west of the 
twenty second meridian west from Washington, thence north to Arkansas River, 
thence up said river to the summit of the Rocky Mountains about west longitude 
29° from Washington, thence along the crest of said mountains northwestwardly 
to the parallel of 42°, thence west to the Pacific Ocean. Our north boundary 
was 49°, as far west as the Rocky Mountains, but west of these we claimed to 
54°, 40'. The strip between 49° and 54° 40' was soon after ceded to Great 
Britain. Oregon included all of the United States west of the Rocky Mountains, 
and Indian Territory all west of Arkansas and Missouri, with Missouri Territory 
lying north, and Iowa extended from Missouri to British America, with Wiscon- 
sin on the east and Missouri Territory on the west. Texas was independent and
