Both Rollo and the Swiss boy immediately put out their oars and pulled; but Gerald soon found that the current was too strong for them. In spite of all they could do, the boat was evidently slowly drifting towards the bridge.

"It is of no use," said Gerald, at last. "We shall have to go through; but that will do no harm if we can only manage to keep her from striking the piers. Take in your oars, boys, and let me pull her round so as to head down stream, and you stand ready to fend off when we are going under."

The excitement of this scene was very great, and Rollo's first impulse was to scream for help; but observing how cool and collected Gerald appeared, he felt somewhat reassured, and at once obeyed Gerald's orders. He took in his oar, and holding it in his hands, as if it had been a boat hook or a setting pole, he prepared to fend off from the piers when the boat went through. In the mean time Gerald had succeeded in getting the boat round, so as to point the bows down stream, just as she reached the bridge; and in this position she shot under it like an arrow. Several boys who were standing on the bridge at this time, after watching at the upper side till the boat went under, ran across to the lower side, to see her come out.

The boat passed through the bridge safely, though the stern struck against the pier on one side, just as it was emerging. The reason of this was, that Gerald, in bringing it round so as to head down the stream, had given it a rotating motion, which continued while it was passing under the bridge, and thus brought the stern round against the pier. No harm was done, however, except that the boat received a rather rude concussion by the blow.

"Now, boys," said Gerald, speaking in French, "we must keep her head and stern up and down the stream, or we shall make shipwreck."

"Yes," said Rollo, in English; "if we should strike a snag or any thing, broadside on, the boat would roll right over."

"A snag!" repeated Gerald, contemptuously. The idea was indeed absurd of finding a snag in the River Rhone; for a snag is formed by a floating tree, which is washed into the river by the undermining of the banks, and is then carried down until it gets lodged. There are millions of such trees in the Mississippi, but none in the Rhone.

However, Rollo was right in his general idea. There might be obstructions of some sort in the river, which it would be dangerous for the boat to encounter broadside on; so he took hold resolutely of the work of helping Gerald bring it into a position parallel with the direction of the stream. In the mean time the boat was swept down the torrent with fearful rapidity. It glided swiftly on amid boiling whirlpools and sheets of rippling foam, that were quite frightful to see. The buildings of the town here bordered the banks of the river on each side, and there were little jutting piers and platforms here and there, with boys upon them in some places, fishing, and women washing clothes in others. The boys in the boat did not call for help, and so nobody attempted to come and help them. Gerald's plan was to keep the boat headed right, and so let her drift on until she had passed through the town, in hopes of being able to bring her up somewhere on the shore below.

At one time the force of the current carried them quite near to the shore, at a place where Gerald thought it would be dangerous to attempt to land, and he called out aloud to Rollo to "fend off." Rollo attempted to do so, and in the attempt he lost his oar. He was standing near the bows at the time, and as he planted his oar against the bottom, the current carried the boat on with such irresistible impetuosity that the oar was wrested from his hand in an instant. If he had not let go of it he would have been pulled over himself. Gerald, however, had the presence of mind to reach out his own oar at once, and draw the lost one back towards the boat, so that the Swiss boy seized it, and, to Rollo's great joy, took it in again.

The boat at one time came very near drifting against one of the great water wheels which were revolving in the stream. Gerald perceived the danger just in time, and he contrived to turn the head of the boat out towards the centre of the river, and then commanding Rollo and the Swiss boy to row, and pulling, himself, with all his force, he just succeeded in escaping the danger.
