"But we will eat first, and afterwards go to the tower," said the king, as he took his guest by the arm. It was a magnificent meal, and Roger, who had seen something of court life in England, for he was often stationed about the palace, knew that this banquet would compare most favourably with anything which King Harry could show. The meats and the dishes were all beautifully prepared, while there was abundant variety. But he had other things in his mind, and was glad when they rose from their couches and went to the tower. From the lofty elevation he was able to see all the outskirts of the city, and when at length he descended it was with the knowledge that orders had already been given for the work of construction to be carried out. "And now for the crossbows and the lances," said Teotlili. "I have already sent orders for the recovery of the Spanish armour and arms, and grieve that we did not trouble about it before. But we never thought of the necessity. Our divers brought up the gold which Malinché attempted to carry off, and after that we did not trouble. Now we will go to the artisans' quarters." They tramped through the city, followed by a crowd of eager natives, while everywhere Roger was treated with the utmost respect. Then they reached the part where the carpenters plied their trade, and here the wood for the crossbows was selected, and one of special toughness, and of somewhat greater length than the steel bow on Roger's weapon, chosen for that portion. "A steel bow would have been better," said our hero, "but as we have none of the metal, wood must do. It will throw a shaft farther than the bows now in use, and a tip of iron to the former will do the rest." Roger's coming was in fact the signal for unusually hard work in and about the city of Mexico, and when three weeks had passed he had the satisfaction of knowing that great strides had been made. Huge chasms now gaped in the causeways, while the edges of these were left steeply sloping, so that an enemy could not easily climb up them. Then archways were left for the secretion of a few canoes, whose crew could dart out at the proper moment and fall on the flank of the enemy. The opening of the aqueduct was also strongly fortified, though it seemed certain that the position could not be held for long. "We will keep the water running till the last moment," said Roger. "Then we must fall back on our store. I should advise that as many as possible of the women and children should be sent out of the city, for then our stores will last longer."
