the singular part is, that right in this neighborhood are many evidences of a system of canals. A glance at the map will show that the portion of Missouri around New Madrid, and to the south of it, is dotted with swampy lakes and sluggish bayous. The evidence is to the effect that the ancient inhabitants connected these bayous and lakes with artificial canals, so as to form quite an extended system of inland water-ways. Right east of the town of Gayoso, we are told that a canal had been dug that now connects the Mississippi with a lake called Big Lake. A bayou running into this lake was joined by a canal with Cushion Lake.
From this last lake, by means of bayous and lakes, a clear course could be pursued for some miles north, where finally another canal was cut to join with the Mississippi a few miles below New Madrid. The entire length of this water way was some seventy miles, but we are not told how much of it was artificial, neither are the dimensions given. Prof. Swallow speaks of a canal "fifty feet wide, and twelve feet, deep." Whether this was one of this series or not, we do not know.<84> This is indeed a singular piece of work. It would be more satisfactory if we had more definite information in regard to the same.
With our present knowledge of the state of society among the Mound Builders, as made evident by the remains of their implements and ornaments, we are not justified in believing this part of a system of internal navigation. We have already seen that further south they sometimes surrounded their village sites with a wide and deep moat or ditch, as was observed around the inclosure containing the great mound on the Etowah. We are inclined to believe that a more careful survey would greatly modify the accounts we have of these canals, if it did not, in fact, show that they were the works of nature. According to a writer in the <i>American Antiquarian,</i><85> the whole lower part of the Mississippi Valley was abundantly supplied with canals, irrigating ditche
