The other principal streams which enter the Mississippi are Fever river, Parasaw, Kaskaskia, and Cahokia. No large streams enter the Ohio or the Wabash, from this State; but some of them are navigable by keel boats.

In the region of Galena are the richest lead mines in the world. Copper ore has also been discovered. The State abounds in mineral coal, which is excellent for the grate. It burns freer than the Pennsylvania coal, and emits much more light. Salt is made in large quantities at the salt works, near Shawneetown.

In the southern part of the State, cotton will grow in a favorable year, and it is cultivated to some extent for family use. This conclusively shows a milder climate than in New-England. In the northern section, in the region of the vast prairies and lakes, the wind sometimes blows strong and keen in the winter. It is not subject to the strong chilly easterly winds so severely felt along the Atlantic coast. During the year, the climate is undoubtedly more mild than that of New-England. Apple, pear and peach trees grow vigorously and produce abundantly. In the spring of the year the air becomes fragrant with the blossoms of fruit trees and wild flowers.

The soil and the climate are well suited to the production of wheat, Indian corn, potatoes, and all garden vegetables. The crops are abundant and of an excellent quality. The prairies every where abound in wild grass, and afford an inexhaustible range for cattle, horses and sheep. The grass is very nutricious, and it may with truth be said, there is not a finer grazing country in the world.

The most prevalent diseases are bilious fevers and the fever and ague. These are caused by stagnant water and swamps. Removed from these, good health is generally enjoyed. The consumption, the scourge of New-England, is never known in all the western country. In some parts of the lower section of the State, the inhabitants have been afflicted with a disease called milk sickness. It, in the first place, affects the cattle, and never occurs until the frosts of autumn. These frosts kill the grass on the high prairies, and induce the cattle to go into the low bottoms and woods, where vegetation remains green. It has been discovered that the disease is caused by the cattle's eating a poisonous vine which grows luxuriantly in these bottoms. After eating this vine, the animal appears weary and faint, travels with difficulty, droops, and at length dies. If men or animals partake of the milk of the cows, when they are thus disordered, they are affected in the same manner. Men, however, sometimes recover. This disease is not confined to Illinois. Near the rich bottom lands in Indiana and Missouri, animals and men have been affected with it. In the northern half of the State, I was informed, that not an instance of milk sickness had ever been known.

There are no large towns in Illinois, but quite a number of flourishing villages. Danville, near the eastern line of the State, is quite a flourishing town; and here the land office for the northern section is kept. It is one hundred and thirty miles south of Chicago, and it is supposed, that the office will shortly be removed to that place. Springfield, situated on a branch of the Sangamon river, is near the centre of the State, and is a large, flourishing village. It is sixty miles south of Peoria, about thirty east of the Illinois river; and it is highly probable that it will become, shortly, the seat of the State government. The most important towns on the Mississippi river, are Galena, Quincy, Alton, Edwardsville, and Kaskaskia; on the Ohio river, are Trinity, America and Shawneetown; on the Wabash, are Palmyra, Lawrenceville, Palestine, Sterling, &c. and in the interior, besides those we have before mentioned, are Vandalia, the present seat of the State government, Jacksonville, Maysville, Hillsborough, Salem, and many other small villages; besides quite a number of paper towns, that may in time have a "local habitation," in addition to their high sounding names.

Chicago is now the largest town in the State; and as it is favorably situated for trade, it will probably continue to take the lead in time to come.—Vandalia, the present seat of government, is pleasantly situated on a high bank of the Kaskaskia river. Respectable buildings for the accommodation of the government and the courts have been erected. The village contains about a hundred houses; some of them, built of brick and elegant.

Kaskaskia is the oldest town in the State. It is pleasantly situated on an extensive plain upon the bank of the river of the same name, and eleven miles from its mouth. It was settled as early as Philadelphia, by the French, and once contained seven thousand inhabitants; but now it numbers not more than one thousand. This was formerly the seat of government; it was removed to Edwardsville, then to Vandalia; but it will probably be destined to take one more remove, either to Springfield or Peoria.

Galena, on the Mississippi, near the northwest corner of the State, began to be settled in 1826. It is three hundred and fifty miles north of St. Louis, and about one hundred and fifty west of Chicago. It now contains between one and two thousand inhabitants, forty-two stores and warehouses, and two hundred houses. It is the seat of justice for the county, and has ten thousand inhabitants in its vicinity.

The same provisions here for schools have been made as in the other western States. In addition to one thirty-sixth part of all the public lands, three per cent. on all the sales is added to the school fund. It is in contemplation to establish an university. For this purpose a sixth part of the school fund and two entire townships have been appropriated. Rock Spring theological school, under the superintendence of the Baptists, is a respectable academy in the Turkey Hills' Settlement, seventeen miles east of St. Louis. It has fifty students.[1] Primary schools are found in the villages and populous neighborhoods; but in many places there is much need of them.
