But I have dwelt long enough on the upper country. I took the stage and travelled twenty-five miles over an open prairie, passing only one house, and arrived at night at Holderman's grove. This is a pleasant grove of excellent timber, having by its side a number of good houses and large cultivated fields. The next morning, we rode fifteen miles to Ottawa, where we breakfasted. Here the Illinois and Fox rivers join, and appear to be nearly of equal size, both about twenty rods wide. The village is on the east side of the Illinois river, which we crossed in a ferry boat. A tavern, some houses and stores are built on a small flat under the hill, and a number of houses on a bluff, two hundred feet above the river. Steamboats come up as high as this place, unless the water be quite low. If it be not a sickly place, I am much mistaken. The fever and ague seems to be the prevailing disease. I have observed that situations on the western rivers are generally unhealthy. The river diverges to the west, and the road down the country immediately leaves it. In travelling twenty-five miles, I found myself fourteen from the river. Here, I left the stage, and went to Hennipen, a small village on the Illinois river. It is regularly laid out on a high, level prairie, which extends three miles back, and consists of two taverns, four stores, a dozen dwelling houses and a court house--it being the seat of justice for Putnam county. I found a number of people sick in this place with the fever and ague. Here I crossed the river, about fifty rods wide, in a ferry boat, and found on the other side about two miles of heavy timbered bottom land, subject to overflow. From this, I ascended a high bluff, passed three or four miles of oak openings, and then came into the open prairie. Ten miles from the river, a new town, called Princeton, is laid out in the prairie, on the stage road leading from Peoria to Galena. Three buildings, one of which is a store where the post office is kept, had been erected when I was there; but as it is in a healthy situation, and surrounded by a beautiful rich country, it may in time become a large village. I travelled some distance in a northerly direction, between great and little Bureau rivers. The larger stream has a number of mills upon it. The country around here, is too similar to the upper part of the State to need a particular description. High rolling prairies, skirted with timber, every where abound in this region, and present to the eye a most beautiful landscape. It is mostly settled by people from New-England; and they appeared healthy, contented and happy--and are in fact, becoming rich and independent farmers.
