The little to be said of Nahua watercraft may be as appropriately inserted here as elsewhere. I have already referred to the important use made of canoes in the transportation of merchandise upon the lakes of Anáhuac. In the art of navigation, however, no progress was made by the Nahuas at all in proportion to their advancement in other respects. As navigators they were altogether inferior to their savage brethren of the Columbian and Hyperborean groups on the north-west coasts, whose skill in the manufacture and management of boats has been described in a preceding volume of this work. The reason is obvious: their progress in agriculture enabled them to obtain a food supply without risking their lives habitually on the sea; their sunny clime obviated the necessity of whale-blubber and seal-skins. In the earlier stages of civilization men make progress only when impelled by some actual necessity; consequently among the Nahuas, when means were supplied of crossing streams, and of transporting goods on the lakes and for short distances along the coast at the mouth of large rivers, progress in this direction ceased.
Clavigero's investigations led him to believe that the use of sails was unknown, and although Brasseur de Bourbourg in one place speaks of such aids to navigation, yet he gives no authority for his statement.[422]
Rafts and 'dug-out' canoes were the vessels employed; the former were used for the most part in crossing streams and were of various material and construction. Those of the ruder kind were simply a number of poles tied together with strings.[423] Those called by the Spaniards balsas were of superior construction, made of otlatl reeds, or tules, and rushes of different kinds in bundles. The best balsas were about five feet square, made of bamboos and supported by hollow gourds closed by a water and air tight covering. The rafts were propelled by swimmers, one in front and another behind.[424]
The canoes—acalli, 'water-houses' among the Aztecs, called also tahucup in Tabasco—were hollowed out from the trunk of a single tree, were generally flat-bottomed and without keel, somewhat narrower at the bow than at the stern as Las Casas says, and would carry from two to sixty persons. As to the instruments employed in hollowing out and finishing the acalli we have no information, neither do we know whether fire was one of the agents made use of.[425]
BOATS USED IN WAR.
The use of boats was not altogether confined to traffic, but extended to war and the transportation of troops. Fierce conflicts on the waters of the lakes are recorded in the ancient annals of Anáhuac; canoe fleets of armed natives came out to meet the Spaniards at various points along the coast; and we read of the vain efforts to defend the approaches to the Aztec capital, by thousands of boats which could offer little resistance to the advance of Cortés' brigantines.[426]
These fleets, so inefficient against Spanish vessels and arms, must have been of great service to the Aztecs in maintaining their domination over the many towns on the lake shores. To increase the efficiency of boats and boatmen, races and sham fights were established, which, besides affording useful training to paddlers and warriors, furnished an additional means of entertainment to the people who gathered in crowds to watch the struggles of the competitors, applaud the ducking of each vanquished boat's crew, and to reward the victors with honors and prizes.[427]
