Reuben Gold Thwaites,
Historic Waterways—Six Hundred Miles of Canoeing Down the Rock…
“ For a dozen miles beyond the Fox River end of the canal the river, as I have before said, is dredged out through the swamp like a big ditch. The artificial banks of sand and peat which line it are generally well grown with mare's-tail, beautiful clumps of wild roses, purple vetch, great beds of sensitive ferns, and masses of Pennsylvania anemone, while the pools are decked with water-anemone. Nature is doing her best to hide the deformities wrought by man. The valley is generally about a mile in width, ridges of wooded knolls hemming in the broad expanse of reeds and rice and willow clumps. ”
