The war canoe does not appear in these early accounts as a special type. According to the traditions of the eastern Micmac and Malecite Indians, their war canoes were only large enough to carry three or four warriors and so must not have exceeded 18 feet in length. These were built for speed, narrow and with very sharp ends; the bottom was made as smooth as was possible. Each canoe carried the insignia of each of its warriors, that is, his personal mark or sign. A canoe carrying a war leader had only his personal mark, none for the rest of the crew. It is possible to regard the large canoes of the Iroquois as "war canoes" since they were used in the pursuit of French raiders in LaHontan's time. However, the Iroquois did not build the canoes primarily for war; in early times these fierce tribesmen preferred to take to the warpath in the dead of winter and to raid overland on snowshoes. In open weather, they used the rough, short-lived and quickly built elm-bark canoes to cross streams and lakes or to follow waterways, discarding them when the immediate purpose was accomplished. Probably it was the French who really produced the bark "war canoes," for they appear to have placed great emphasis on large canoes for use of the military, as indicated by LaHontan's concern with the largest canoes of his time. Perhaps large bark canoes were once used on the Great Lakes for war parties, but, if so, no mention of a special type has been found in the early French accounts. The sparse references suggest that both large and small canoes were used by the war parties but that no special type paralleling the characteristics of the Micmac and Malecite war canoes existed in the West. The huge dugout war canoe of the Indians of the Northwest Coast appears to have had no counterpart in size among the birch or elm bark canoes. Except for LaHontan, the early French writers who refer to the use of sail agree that the canoes were quite unfitted for sailing. It is extremely doubtful that the prehistoric Indians using bark canoes were acquainted with sails, though it is possible that the coastal Indians might have set up a bush in the bow to utilize a following wind and thus lighten the labor of paddling. However, once the Indian saw the usefulness of a sail demonstrated by white men, he was quick to adopt it; judging from the LaHontan reference, and the use of sails in canoes must have become well established in some areas by 1685.
