The impression has formerly existed abroad, that Illinois is less healthy than other western states. This is entirely erroneous. As in all countries, there are some localities, where the causes that produce sickness exist more than in others. This is not the fact with Illinois in general.
That this state is as healthy as any other western state, can be abundantly supported by facts. Let a candid observer compare the health of the early settlers of New England, with that of the early settlers of the West, and he will find the scale to preponderate in favor of the latter. Unless there is some strange fatality attending Illinois, its population must be more healthy than the early settlers of a timbered region. But in no period of its history have sickness and death triumphed, in any respect equal to what they did two or three years since, in the lake country of New York.
The year 1811, is recorded in the memoirs of the early settlers, as a season of unusual sickness near the banks of the Mississippi and Missouri rivers. The latter river rose to an unusual height in June, the waters of the small creeks were backed up, and a large surface of luxuriant vegetation was covered and deadened. This was succeeded by hot and dry weather. Bilious and intermittent fevers prevailed extensively. The seasons of 1819, '20, and '21 were usually sickly in Illinois and Missouri. Emigrants, in shoals, had spread over a wide range of country within a year or two preceding. Multitudes were placed under circumstances the most unfavorable to the preservation of health, in new and open cabins of green timber, often using the stagnant water of creeks and ponds, with a luxuriant vegetation around them undergoing decomposition, and all the other evils attendant on the settlement of a new and unbroken country. Under such circumstances, can it be surprising that many were sick, and that many died? The summer of 1820 was the hottest and driest ever known in this country. For weeks in succession, the thermometer, in the shade at St. Louis, was up to 96° for hours in the day. Not a cloud came over the sun, to afford a partial relief from its burning influence. The fevers of that season were unusually rapid, malignant, and unmanageable. Almost every mark of the yellow fever, as laid down in the books, was exhibited in many cases, both in town and country. The bilious fever put on its most malignant type. Black, foetid matter was discharged from the stomach, and by stools. The writer and all his family suffered severely that season. He lived seventeen miles from St. Louis, on the road to St. Charles in Missouri, on a farm. The settlement had been called healthy. The Missouri bottom was one mile distant. Three miles west southwest, was the Creve-coeur lake, a body of water several miles in length and half a mile in width, connected by an outlet with the Missouri river. The water of this lake was entirely stagnant, covered with a thick scum, and sent forth a noisome smell. Fish in it died. My oldest son, a robust youth of ten years of age, and my brother-in-law, a hale and stout young man, sickened and died the first week in October. I was attacked the 5th day of July, came as near dying as a person could and recover. All my children were sick. While convalescent, in September, I took a long journey to Cape Girardeau country, 120 miles south, and back through the lead mine country to the Missouri river, 60 miles west of St. Louis, and in all the route found that sickness had prevailed to the same extent.
