The thwart is carefully fitted to the gunwale members and the ends are pegged. Some builders wedged the ends of this thwart from outside the gunwales, the wedge standing vertical in the thwart so that the gunwale would not split; however, it is not certain that wedging was used in prehistoric times, although it is seen in some existing old canoes. The pegs used in this canoe are driven from above, into holes bored through the gunwale and the tenon of the thwart to lock all firmly together. Three holes are then bored in the broad shoulders of the thwart about 1½ inches inboard of gunwale for the root lashing that is also used. The ends of the gunwale members are now brought together, and to avoid an unfair curve appearing at the thwart in place, short pieces of split plank or of sapling, notched to hold them in place, are inserted between the gunwale members as temporary thwarts at points about 5 feet on each side of the middle thwart. After the ends are brought together and the final fitting is carried out, a peg is driven athwartships the ends and a single-part root lashing is carefully wrapped around the assembly. Some canoe builders omitted the blunted half-arrowhead form at the gunwale end. Instead, the inside faces were tapered to allow the two parts to bear on one another for some distance. The gunwales were then pinched together and lashed with one or more wrappings. Finally, a thin wedge was sometimes driven from inboard between the two gunwale ends to tighten the wrappings. The wedges were usually so carefully fitted as to be difficult to identify. It is probable that this wedged gunwale ending represents the prehistoric form, and the blunted half-arrowhead ending is a result of the use of steel tools.
