[build, after the manner of barges which ye have hitherto built.]: We do not know why we get the description of the barges at the second building rather than the first. Perhaps the original text described then for the first journey, but Moroni elected to describe them here because of his interest in warning his future readers that comes on the heels of the first mention. In any case, the fact that the barges must be built again suggests that they had been dismantled during the four years to supply living materials to the small colony.
