These are the passages that mention it, exactly as the scans read.
Tlie township of New Boston embraces congressional to-^aiship 14 north, and ranges 5 and 6 west, extending to the Mississippi river. The eastern part is undulating and contains a depth and richness of soil unexcelled in the county. The westeiTi part of the township is level, containing a narrow strip of sandy soil, in some places almost destitute of vegetation ; between this strip and the undulating region of the east the bottom land is extremely fertile and })roduces heavy crops.
To Mr. William Denison and his son John W. belong the honor of planting the first settlement in the township, as well as in the county. They were Pennsylvanians, and came directly fi-om Wa}Tie county, Indiana, ha%nng previously lived for a short time in Ohio. They settled near the site of the present town of New Boston in ] 827, and there lived in close and friendly relations with the Indians who at that time frequented the place. The \'icinity offered many attractions to the Indians in the shape of hunting and fishing ; and, indeed, at the present time it has more than a local celebrity in this respect.
Let the reader pause here a moment and call to aid his imagination in picturing a settlement of this kind. On the one hand a boundless waste of prairie, covered with tall waving grass, which sinks and rises with a billow}- motion, as far as the eye can reach. On the other lumd the great Father of "Waters, spread out in silent majesty, or lashed to fiiry by the untrammeled winds which sometimes sweep over the ])lains from the west. Here was to be found the savage in his native wildness. Here he smoked his pipe of peace or hallooed his wnld war-dance. And here was started the first settlement of what was to be, at a tuture time, one of the myriads of fair towns that dot the broad State of Blinois.
