Reading edition
Mr. A. J. Conant in the Commonwealth of Missouri, pp. 77–8 (St. Louis, 1877), refers to ancient canals fifty feet wide and twelve feet deep observed by Dr. G. C. Swallow. He quotes a pretty full account from Geo. W. Carleton, Esq. Mr. Conant considers some of the southern bayous of artificial origin.
