In the seventeenth and the early part of the eighteenth centuries the buffalo ranged as far east as western New York and Pennsylvania, and as far south as Virginia, the Carolinas and Georgia. Father Marquette, in his explorations, declared that the prairies along the Illinois river were "covered with buffalos." Father Hennepin, in writing of northern Illinois, between Chicago and the Illinois river, asserted that "There must be an innumerable quantity of wild bulls in this country, since the earth is covered with their horns. * * * They follow one another, so that you may see a drove of them for about a league together. Their ways are beaten, as are our great roads, and no herb grows therein." Of the presence of large numbers of buffalo, that resorted to the salty licks of Kentucky, we have frequent mention by both Humphrey Marshall and Mann Butler, the early historians of that state. In the year 1755, Colonel James Smith mentions the killing of several buffalo by the Indians at a lick in Ohio, somewhere between the Muskingum, the Ohio and the Scioto. At this lick the Indians made about a half bushel of salt in their brass kettles. He asserts that about this lick there were clear, open woods, and that there were great roads leading to the same, made by the buffalo, that appeared like wagon roads. The wild cattle had evidently been attracted thither by the mineral salts in the water. In the early morning of June 13, 1765, George Croghan, an Indian agent sent out by William Johnson, of New York, to report to the English government conditions in the west, coming into view of one of the fine large meadows bordering on the western banks of the Wabash, saw in the distance herds of buffalo eating the grass, and describes the land as filled with buffalo, deer and bears in "great plenty." On the 18th and 19th of the same month, he traveled through what he terms as a "prodigious large meadow, called the Pyankeshaw's Hunting Ground," and describes it as well watered and full of buffalo, deer, bears, and all kinds of wild game. He was still in the lower Wabash region. On the 20th and 21st of June he was traveling north along the Wabash in the vicinity of the Vermilion river in Vermilion county, and states that game existed plentifully, and that one could kill in a half hour as much as was needed. He spoke, evidently, of the large variety of game before mentioned. The whole of the prairie of Illinois, filled with an abundant growth of the richest grasses, and all the savannas north of the Wabash in Indiana, that really constituted an extension of the Grand Prairie, were particularly suited to the range of the wild herds, and were the last grounds deserted by them previous to their withdrawal west, and across the Mississippi.
