This was a specimen of the incessant complaining of the people, whom the heat and thirst seemed to rob of every scrap of patience and endurance that they might have originally possessed.

But somehow, in spite of all their troubles, the day wore on, and Bart kept hopefully looking out for a glimpse of the water ahead.

They ought to have reached it long before, but the pace of the weary oxen had been most painfully slow. Then the wind, what little there was, had been behind them, seeming as out of the mouth of some furnace, and bringing back upon them the finely pulverised dust that the cattle raised.

At last, towards evening, the sky began again to cloud over, and the mountain that had appeared distant seemed, by the change in the atmosphere, to be brought nearer to them. Almost by magic, too, the wind fell. There was a perfect calm, and then it began to blow from the opposite quarter, at first in soft puffs, then as a steady, refreshing breeze, and instantly there was a commotion in the camp,—the cattle set off at a lumbering gallop; the mules, heedless of their burdens, followed suit; the horses snorted and strained at their bridles, and Joses galloped about, shouting to the teamsters in charge of the waggons, who were striving with all their might to restrain their horses.

“Let them go, my lads; unhitch and let them go, or they’ll have the waggons over.”

“Stampede! stampede!” some of the men kept shouting, and all at once it seemed that the whole of the quadrupeds were in motion; for, acting upon Joses’ orders, the teams were unhitched, and away the whole body swept in a thundering gallop onward towards the mountain, leaving the waggons solitary in the dusty plain.

Every now and then a mule freed itself of its pack, and began kicking and squealing in delight at its freedom, while the cattle tossed their horns and went on in headlong gallop.

For once the wind had turned, the poor suffering beasts had sniffed the soft moist air that had passed over the shallow lake, and their unerring instinct set them off in search of relief.

There was no pause, and all the mounted men could do was to let their horses keep pace with the mules and cattle, only guiding them clear of the thickest part of the drove. And so they thundered on till the dusty plain was left behind, and green rank herbage and thickly growing water-plants reached, through which the cattle rushed to the shallow water at the edge of the lake.

But still they did not stop to drink, but rushed on and on, plashing as they went, till they were in right up to their flanks. Then, and then only, did they begin to drink, snorting and breathing hard, and drawing in the pure fresh water.
