Scattered here and there, too, were pebbles of a brownish tint, with rounded corners, very like shingle, and about the size of nuts.

When Mr. Wolston and Ernest reached the dam they discovered that the Montrose was unnavigable for a good mile and a half. Its bed was obstructed with rocks among which the water boiled, and the portage of a canoe up stream would be a very laborious business.

The country appeared to be absolutely barren right up to the foot of the range. For any trace of verdure it was necessary to look towards the north-west and north, in the direction of the Green Valley, the distant forests of which could just be seen on the boundary of the Promised Land.

So there was nothing for it but to retrace their steps, and this Mr. Wolston and Ernest did, greatly regretting that the Montrose was blocked in this portion of its course.

As they went along the winding gorge Ernest picked up a few of the brownish pebbles, which were heavier than their size seemed to warrant. He put a couple of the little stones in his pocket with the intention of examining them when he got back to Rock Castle.

It was with a good deal of vexation that Mr. Wolston turned his back on the south-western horizon. But the sun was getting low, and it would not have done to be belated so far from the encampment. So the canoe took to the stream once more, and, driven along by the paddles, made good speed down the river.

At six o'clock the whole party was gathered together again at the foot of the clump of evergreen oaks. M. Zermatt and Jack were well satisfied with their sport, and had brought back an antelope, a brace of rabbits, an agouti, and several birds of various kinds.

The little tributary of the Montrose watered a very fertile tract of country, sometimes crossing plains which were admirably suitable for raising grain, sometimes running through dense woods. There were also game districts where the sound of the sportsman's gun had almost certainly just been heard for the first time.

A good dinner was waiting for the men after their excursion. It was served under the shadow of the trees, on the bank of the stream, whose running waters murmured over their sandy bed, sprinkled with aquatic plants.

At nine o'clock all went to their berths aboard the Elizabeth to sleep well and soundly.
