This county bears the name of the celebrated Polish soldier. Count Pulaski, who, failing to sustain the Independence of his own country, came to this during the revolutionary war, was appointed a brigadier general, and fell, mortally wounded, in the attack on Savannah, in 1779. The surface of the county is mostly level, though in several parts there are ridges of low sandy hills. About one half of the county is prairie; the other half oak openings, though portions of it have a very heavy growth of the various species of oak timber. A few of the bottoms of the Tippecanoe and other streams have small groves of walnut, sugar tree and white maple, and the soil is well adapted to the growth of fruit trees. An arm of the Grand Prairie extends several miles into the southwest corner of the county. The other principal prairies are Fox-grape, Dry, Northwestern, Oliver's, and Pearson's. The west prairies are favorable for grazing, and, through a process of drainage, they are being rapidly improved, so as to be cultivated with profit. The dry prairies and openings are mostly a black loam mixed with sand, and occasionally a good deal of mud, and are well adapted to wheat, corn, oats, etc.
Winnemac, the county seat, is located a little to the east of the center of the county. It is a flourishing town, with good railroad facilities, educational advantages, and commercial thrift. The county is well settled and in a very prosperous condition.
