Not long after this, the boys perceived, far out on the sultry plain, a sudden swirl of dust.
"Something coming," shouted Tubby, who, strange to say, had been the first to notice the approaching column of dust.
"Team," briefly grunted the landlord, "did I hear you fellers say you was waiting for some one from the Harkness range?"
"Yes, you did," said Rob.
"Waal, I guess that's them now. Must have a bear-cat of a team in to kick up all that smother."
Closer and closer grew the dust cloud, and presently, from its yellow swirls, emerged the heads of the leaders of an eight-mule team. Behind them lumbered a big, broad-tired wagon, from the bed of which a high seat was reared like a watch tower. By the driver's side was a long iron foot brake. As the team approached the bank of the sandy little dried-up river, where the road took a dip, the driver placed his foot on the brake and a loud screeching and groaning resulted, as the big wagon, with the hind wheels locked, slid down the far bank. As the front wheels thundered across the rough bridge above the thin thread of luke-warm water, the heads of the first mules emerged over the top of the bank nearest the hotel.

"Sorry to have kept you waiting so long," responded the other, who in order to speak had pulled down a big red handkerchief which had bundled up the lower part of his face and kept it dust-proof while he drove; "but the fact is, we had some trouble on the way. A bunch of Moquis are out, and——"
