"Don't you think we have shaken them off?" asked Ned.
"No," replied Obed. "They would scatter toward dawn and the one who picked up the trail would call the others with a whoop or a rifle shot."
"Well, they've been called," said Ned, who was looking back. "See, there, on the highest ridge."
A faint, dark blur had appeared on a crest three or four miles behind them, one that would have been wholly invisible had not the air been so clear and translucent. It was impossible at the distance to distinguish shapes or detach anything from the general mass, but they knew very well that it was the Lipans. Each felt a little chill at this pursuit so tenacious and so menacing.
"I wish that we had some sort of a place like that in which we faced the Mexicans, where we could put our backs to the wall and fight!" exclaimed Ned.
"I know how you feel," said Obed, "because I feel the same way myself, but there isn't any such place, Ned, and this plain doesn't ever give any sign of producing one, so we'll just ride on. We'll trust to time and chance. Something may happen in our favor."
They strengthened their hearts, whistled to their horses and rode ahead. As on the day before the interminable pursuit went on hour after hour. It was another hot day, and their water bottles were almost emptied. The horses had had nothing to drink since the day before and the two fugitives began to feel for them, but about noon they came to a little pool, lying in a dip or hollow between the swells. It was perhaps fifty feet either way, less than a foot deep and the water was yellowish in color, but it contained no alkali nor any other bitter infusion. Moreover, grass grew around its edges and some wild ducks swam on its surface. It would have been a good place for a camp and they would have stayed there gladly had it not been for that threat which always hung on the southern horizon.
The water was warm, but the horses drank deeply, and Ned and Obed refilled their bottles. The stop enabled the pursuing Lipans to come within a mile of them, but, moving away at an increased pace, they began to lengthen the gap.
"The Lipans will stop and water their ponies and themselves just as we have done," said Obed. "Everything that we have to endure they have to endure, too. It's a poor rule that doesn't work for one side as well as the other."
"It would all look like play," said Ned, "if we didn't know that it was so much in earnest. Just as you said, Obed, they're stopping to drink at the pond."
