The surface of the greater portion of this township is remarkably level; a small portion in the eastern part and along the Big Darby is rolling and slightly hilly, while the central and southern portions are a part of the celebrated "Darby Plains," noted for their level surface, and deep, rich soil, consisting of black vegetable mold. Originally, as the first settlers found these plains, they consisted of prairie and oak openings, the former covered with an exuberance of grass, which in some portions grew to an enormous height; some of the settlers testifying that, as they rode through it on horseback, they could grasp a handful on each side of the horse, and tie them together over the rider's head. This is an excellent grazing and stock country, and from its first settlement, the people have devoted much of their time and attention to the stock business. During a few years of recent date, they have given attention to ditching, tiling and draining these lands, which are thus rendered excellent for corn and wheat. Here, as elsewhere, the first settlers sought the higher and more rolling lands, along the streams, upon which they located, considering the prairies on those plains as worthless; too flat and wet to ever admit of cultivation, or even to be habitable. But early in the settlement of this township, colonies from the New England States came here, and, appreciating the true value of these rich lands, with true sagacity and sound judgrpent selected and located upon them; and although, for some years, they endured sickness, and inconvenience attendant upon the work of first improvement, and caused largely by decaying vegetation, yet now they are possessed of as fine farms as can be found in the State. When these prairies were first taken up, they were pu,rchased for about one-half the price of the higher and more rolling lands, a lai-ge area being bought for 60 to 75 cents per aci'e, now they are worth about tAvice as much per acre as the hilly clay lands. This, township is well watered. The Big and Little Darby, with their many tributaries, drain almost every part of the township. The Big Darby enters this township in its northwestern portion, and courses in a southeastern direction, leaving the township on its eastern border, about midway between the northern and southern boundaries. In its course, commencing in the northwest corner of the township, it receives from the southwest the following tributaries: Watson Run, Hay Run and Prairie Run; from the north or east side it receives Buck Run, which cou.rses entirely through the northeastern portion of the township in a southeastern course, emptying into the Darby at the east boundary line. The Little Darby enters this township near its southwest corner, from Madison County, courses northeast until it receives Treacle Creek, thence flows southeast and leaves the township at its extreme southeast corner. Treacle Creek is its principal tributary, and enters from Champaign Connty, near the southwest corner of the township, about one-half mile west of L^win Station. It courses northward about two and one half miles, thence east one and a half miles, thence south to the Little Dai-by, inclosing with the latter a large tract of probably 3,000 acres of land, and almost making an island of it, there being only an isthmus in the northwest corner of the township, between the head-waters of Treacle Creek and Little Darby, of about one-half mile in width.
