As they entered the main road they turned in just ahead of a rickety farm wagon with flimsy makeshift cotton hood, containing a strange medley of children, women, household furniture, what-not. It was drawn by a cow and a gaunt horse, a goat was led at the rear, a dusty, sallow man trudged alongside. The wagon-hood said: "Noah's Ark." "How'll you swap outfits, strangers?" sung the man. "Nary swap," laughed Harry. "Whar you from?" "Up the Blue." "We're from Injianny," quavered one of the women, on the front seat. "It's a powerful long way to the gold fields, isn't it?" "You've hardly started yet," replied Harry. "But just keep a-going." And--"Whoa, Duke! Look out, there! Gee! Gee-up!" He thwacked Duke smartly on the shoulder with the willow pole, and ran to his head. The road before and behind was thronged with the travelers, and Duke, not accustomed to so much confusion, had been waxing restive. He snorted, his eyes bulged, his little tail jerked, and he made a side-ways jump at an annoying dog. Out flew Shep, rolled the dog over and over until he fled yelping, while with rapid commands Harry quieted Duke. Even Jenny the yellow mule was showing symptoms of rebellion. "We'll never get into town, this way," panted Harry. "Let's drive around and on to the river and unspan for noon. Then you watch Duke, and I'll ride Jenny back in for supplies." So, picking their path, they began to circuit the little town. To do this was considerable of an undertaking, for the tents and wagons and people were scattered everywhere over the prairie, and Duke much resented the shouts and laughter and smoke and barking dogs and the incessant orders from Harry. His eyes bulged, he rumbled indignantly, he shook his head, the froth dripped from his lips. On a sudden a mean little cur darted from one side and nipped him in his heel--and this was the last straw. With a lunge and a kick away he bolted, dragging the surprised Jenny until she also lost her temper, and together they dragged the cart. Harry ran, shouting. Terry ran. Shep yapped excitedly. "Stampede!" "Look out for the buffalo!" "Hi! Hi!" "Head 'em off!" Women hastily clutched children, men waved their arms and hats. "Duke! Jenny! Whoa! Whoa!" vainly yelled Harry and Terry, following at best speed in the wake of the lurching cart. Through among the camps galloped Duke and Jenny--Duke cavorting, Jenny plunging, the cart bounding and skidding, the pails and cooking utensils rattling, people scampering from the path; and Harry and Terry, in their heavy boots, pursuing, wild with alarm. Something serious was likely to result.
