"Yes, they undoubtedly followed orders."
"And perhaps exceeded them," added the Professor.
It was a real supper that they sat down to that evening, with hot coffee, fried bacon and other good things, and the party would have been a jolly one had Tad and Stacy been on hand to participate in it.
Walter hurried through his meal, then took his position on the hill once more, where he renewed his signaling with the rifle.
All at once he uttered a shout, following it with a quick volley of six shots, thus emptying his magazine.
"Do you see them!" called Parry, hastening over to the knoll, and joining Walter.
"I think I see a cloud of dust approaching over the desert," he made reply.
"Where?"
Walter pointed with his rifle.
"Yes, that's the boys, I guess. Nothing but a broncho could kick up the alkali like that. I'll go back and have their supper ready. You keep on shooting. The light is growing fainter and they won't be able to find their way in otherwise."
