Rh with new hope, for they knew that on these arid wastes, in the neighborhood of trees, there is always water. They now quickened their pace; the horses seemed to understand their motives, and to partake of their anticipations; for, though before almost ready to give out, they now required neither whip nor spur. With all their exertions it was late in the night before they drew near to the trees. As they approached, they heard with transport, the ripping of a shallow stream. No sooner did the refreshing sound reach the ears of the horses, than the poor animals snuffed the air, rushed forward with ungovernable eagerness, and plunging their muzzles into the water, drank until they seemed in danger of bursting. Their riders had but little more discretion, and required repeated draughts to quench their excessive thirst. Their weary march that day had been forty-five miles, over a track that might rival the deserts of Africa for aridity. Indeed, the sufferings of the traveller on these American deserts is frequently more severe than in the wastes of Africa or Asia, from being less habituated and prepared to cope with them.

On the banks of this blessed stream the travellers encamped for the night; and so great had been their fatigue, and so sound and sweet was their sleep, that it was a late hour the next morning before they awoke. They now recognized the little river to be the Umatalla, the same on the banks of which Mr. Hunt and his followers had arrived after their painful struggle through the Blue Mountains, and experienced such a kind relief in the friendly camp of the Sciatogas.

That range of Blue Mountains now extended in the distance before them; they were the same among which poor Michael Carriere had perished. They form the south-east boundary of the great plains along the Columbia, dividing the waters of its main stream from those of Lewis River. They are, in fact, a part of a long chain, which stretches over a great extent of country, and includes in its links the Snake River Mountains. The day was somewhat advanced before the travellers loft the shady banks of the Umatalla. Their route gradually took them among the Blue Mountains, which assumed the most rugged aspect on a near approach. They were shagged with dense and gloomy forests, and cut up by deep and precipitous ravines, extremely toilsome to the horses. Sometimes the travellers had to follow the course of some brawling stream, with a broken, rocky bed, which the shouldering cliffs and
