John was torn betwixt hope and bitter disappointment.
"Do you think they could climb out of the fissure?" he asked half a dozen times, then without waiting for an answer, "Did you see her face, Billy? I had just a glimpse! Didn't she look well! Just that one glance has put new life in me! I know we will get her! Even this cursed desert isn't wide enough to keep me from her! God help that Indian when I get him!"
Porter kept his eyes on Alchise's rifle which had never wavered in the past three hours.
"I've a notion to shoot the barrel off that thing just for luck!" he growled. "John, sit down! You will need all the strength you've got and then some before you catch that Injun!"
"What are you going to do?" asked John, seating himself in the sand some few feet from the fissure.
"The big probability is," said Billy, "that they are in the crack. It would be just about impossible for a girl to climb out of one of 'em. If they have got out, though, it's just a matter of finding their trail again. We'll have 'em! It's just this chance crack that saved 'em. If you're rested, ride along the west wall and try for the top again."
For the next five hours, Porter guarded the mesa front alone. It was nearing six o'clock when Jack returned, exhausted and disappointed. He had followed the great split back until the mesa top became so cut and striated with mighty fissures that progress was impossible.
"Isn't it the devil's own luck," he growled to Porter as he ate, "that we should have let him get into that one crack! What next! Unless they are still in there, we've lost them and are just losing time squatting here."
As he spoke, there was a sound of voices in the fissure. The two men cocked their rifles as John and Carlos emerged from the opening. John was scowling and breathless.
"Lost 'em as usual, by our infernal stupidity," he panted, while Carlos dropped his empty canteen and lifted Porter's to his lips. "I rode round to the south of the mesa. There are a couple of possible ascents there. I found Carlos making one. We followed a dozen fissures before we located this one. We got into it about a mile back from here. Here's a basket we found at the bottom in a burlap bag."
He tossed one of Cesca's pitch baskets at Billy, then threw himself in the sand.
"They were down off the mesa, I bet," he went on, "before we fools found the way up, and it was easy for the chap they left guarding the entrance to avoid us. The mesa is covered with big rocks."
