They pushed the raft silently across the water, and drew it up for safety, and then stole down to the water's edge to make their way beyond the sight of the savages on the opposite side. All along the shore advantage was taken of every piece of wood available to serve as a floating structure, and when the wood was reached a few of convenient size were selected and cut up into lengths which would enable them to be readily rolled down to the river.

This work occupied them until midnight, and four large trees were thus prepared and lashed together, and one, wading in the water along the beach, using a pole, the other, with the rope, they held it within poling distance of the shore. In this manner the logs and detached pieces were floated down to the mouth of the stream, and having tied the small raft to the stern, it was finally poled across and landed at the water's edge not far from the wagon.

It was fortunate that the water was shallow and that the beach was shelving at this point, as it materially aided in effecting the launching. The moon went down before four o'clock that morning, and the yaks were yoked up and led to the river.

When Harry returned he was surprised at what he saw in their camp. The Professor and George had been at work also. Several uprights had been put up on the side of the wagon facing the besiegers, and over this had been stretched an old canvas and parts of such goods as could be dispensed with, so as to imitate the wagon, as nearly as possible.

Their ramie fiber top was of a light yellowish color, which looked bright in the moonlight. This had been removed and stored in the wagon, so that when the wagon was driven away the sham arrangement did not disclose the disappearance of the vehicle.

The wagon was driven into the water nearly hub deep, and two of the largest logs were then floated in under the axles, and the smaller ones lashed inside, so that the sustaining power of the combined logs, together with the wooden portion of the wagon and body, would be sufficient to sustain their weights.

Harry worked liked a hero, and took personal charge of the handling of the team, which was his especial delight. His presence near the yaks always gave them confidence, and on this occasion he took his position on the pole between them and near the yoke, and thus gently urged them forward.

For twenty-five feet or more the wheels kept on the ground, but soon thereafter the wheels were free, and they were delighted to find that the timbers did not permit the body to go down very low into the water, and this saved their bedding from becoming soaked.

The yaks performed their work nobly. Some months before they had forded the South River, at the time the flagpole for Observation Hill was cut, so they had ample reason to believe that they would be dependable under these circumstances. It did not require much urging on the part of Harry, and the opposite bank was soon reached, and the cattle scrambled up the beach, but were stopped before the wagon emerged from the water so the logs could be cut adrift.
