"They'll have to camp pretty soon. We'll come into 'em, if we keep going," encouraged Harry. And he added, suddenly: "Look at Jenny! She smells water. And so does Duke!"

For both Duke and Jenny were alertly stretching out—sniffing, tugging, trying to increase their pace. They almost trotted. Could they really smell water in barrels, away off there—or did they guess? At any rate, the two routes were drawing together.

The sun sank below the horizon, and a pleasant coolness flowed over the landscape. Now in the twilight the freighter outfit had halted, and bunched. Going to make camp? No—there it started again. Pshaw! But no—some of it had remained: not the wagons, but several of the loose stock, and two men, and a heap of stuff.

"Hurrah!" gasped Harry. "That's enough. Enough for us."

Duke and Jenny were trying to break into a gallop, and their owners had hard work to keep up. The party at the camp had seen them coming, and were pausing in their camp-making to stare. Now at a staggering lope and trot the Pike's Peak Limited fairly charged in—would have run right over the camp had not the two men there rushed out and waved their arms and shouted.

The camp was on the edge of a muddy creek course. That was what ailed Duke and Jenny; only by main force could they be held back.

"What's the matter? Plumb crazed?" scolded one of the men.

"Their critters are plumb crazed, don't you see?" reproved the other. "Unhook 'em and let 'em go, or they'll drag cart and all in."

Harry hustled, Terry hustled, the men helped—and on sprang Duke and Jenny, into the mud, into the water, to drink, and gulp, and drink again, and stand there, belly deep, soaking. Terry yearned mightily to join them, but Harry was more polite.

"Whar you from? You look nigh tuckered out, yourselves," accused one of the men.
