"And they are close enough to be taken before they could get clear," burst in Philip. "In the confusion some might become entangled, and then——"

"We would send our canoes against them," exclaimed Roger. "'Tis a grand idea, and we will see what can be done. I will speak to Teotlili."

"We have resin here in abundance," said the latter, when the question was put to him, "and there are other inflammable matters. The plan may well be tried, and may succeed at first. But they will not be caught twice. Later on the houses will protect us."

He went off at once to make arrangements, and his men worked with such energy that when the Spaniards had contrived to fill in the far gap, and were preparing to advance again, a couple of craft composed of three canoes lashed together, lay in recesses beneath the causeway, their boards piled high with resin and other matters.

"And now comes the question of who is to take command," said Roger. "These natives are so terrified at the sound of the cannon that they will hardly fill the post. I will gladly take one canoe."

"And I a second," burst in Philip. "But you should not go, Roger, if you will forgive my saying so. You are the commander here. The king and all look to you, and already you have had one narrow escape. You are too valuable to the defence, and should protect your life as long as possible. I will go for one."

"And by your leave I will sail the second," exclaimed Peter, all aglow at the prospect. "There is little to do. We must push out, and pole along gently. Then, as we get to close quarters, we will fire the mass and leap overboard."

"Then it shall be arranged as you say. I will stay behind and will lead the attack. It is already getting dusk, and perhaps, if we delay a little, you will be able to get out to the brigantines without being seen. If that is the case we may do them some damage. I will have men armed with the crossbow in canoes, ready to take advantage of the confusion. Go to your places and prepare. I will send to you when the moment comes."

He dismissed them with a nod, and went to the barricade erected on the causeway. Like that at the last gap, it consisted of sun-dried bricks, and was so thick that it offered an effective resistance to the cannon-shot of the enemy. On its landward side there was a gaping chasm where the causeway had been entirely removed, and this the enemy now proceeded to fill, just as they had done in the case of the other one. Thanks to the huge amount of native labour which their allies provided, there was no difficulty about the matter, and for material there was the stone and bricks from the houses and forts built at the extreme land end of the viaduct. Already the Spanish allies had levelled these, and now they came in their thousands, each carrying a boulder, a beam, or some dozen bricks, which they threw into the gap. While they worked, the soldiers kept up a furious fire against the barricade beyond, while their crossbow-men sent shafts humming through the air. Then the brigantines hove up the stone anchors which each had cast, and poling higher up, dropped anchor in a position which gave them a clear and close range.

"Let the crossbow-men alone stand behind the barricade and pick off the enemy and hamper the work of filling in the ditch," cried Roger, calling Teotlili's attention. "The others are to throw themselves on their faces, and in that way they will escape the shot from the brigantines."
