booty of trifling value. After a fortnight of rapid marching, fighting and reconnoitering, Cortéz and his men returned to Tezcoco. Here he was met by an embassy from the friendly Chalcans and pressed for a sufficient force to sustain them against the Mexicans, who despatched the warriors of certain neighboring and loyal strongholds to annoy the inhabitants of a town which had exhibited a desire to fraternize with the invading Spaniards. Indeed, the Aztecs saw the importance of maintaining the control of a point which commanded the most important avenue to their capital from the Atlantic coast. The wearied troops of Cortéz were in no plight to respond to the summons of the Chalcans at that moment, for their hurried foray and incessant conflicts with the enemy had made them anxious for the repose they might justly expect in Tezcoco.

This duty he soon successfully performed. But the Aztecs renewed the assault on Chalco with a fleet of boats, and were again beaten off with the loss of a number of their nobles, who were delivered by the victors to Sandoval whom Cortéz had sent back to support the contested town as soon as the news of the fresh attack reached him.
By this time the brigantines were nearly completed, and the canal dug by which they were to be carried to the waters of the lake, for, at that time, the town of Tezcoco was distant from its margin.

Nor was his heart uncheered by fresh arrivals from the old world. Two hundred men, well provided with arms and ammunition, and with
