 by the Spanish fleet, and plied their archery with such galling effect, that the Spaniards were forced to make a temporary breach in the dike, wide enough to admit two of their own smaller vessels, which, passing through, soon obtained an entire command of the interior basin, as they before had of the outer. Still, the bold barbarians, advancing along the causeway, marched up within bow-shot of the Christian ramparts, sending forth such yells and discordant battle-cries, that it seemed, in the words of Cortés, "as if heaven and earth were coming together."

On the day appointed, his forces were under arms with the dawn. Mass, as usual, was performed; and the Indian confederates, as they listened with grave attention to the stately and imposing service, regarded with undisguised admiration the devotional reverence shown by the Christians, whom, in their simplicity, they looked upon
