“Her hoss ain’t there neither,” said Thad, and again he looked up at the dark, rolling clouds.

“Oh, she’ll be comin’ along in a minute or two,” offered Bob soothingly, but his voice betrayed the anxiety his words were meant to hide.

Marta was no novice in the mountains, and the old Pardners knew that it was not like their girl to ignore the near approach of a storm that would in a few moments change the murmuring cañon creek into a wild, roaring flood that no living horse could ford or swim. The trail, on its course from her home to the Burtons, and to Oracle, crossed and recrossed the creek many times, and should the storm break in the upper cañon at the right moment, it would easily be possible for the girl to be trapped at some point between the cañon walls and the bends of the stream, and forced to spend at least the night there. More than this, there was a place where the trail followed for some distance up the narrow, sandy bed of the creek itself, between sheer cliffs. The Pardners and Marta had more than once seen a rolling, plunging, raging wall of water come thundering down the cañon from a storm above, with a mad force that no power on earth could check or face, and with a swiftness that no horse could outrun.

A few scattered drops of rain came pattering down. The Pardners without another word hurried over to Edwards’ cabin.

The younger man, who was coming up the path from his work, greeted them with a cheery, “Hello, neighbors—looks like we’re going to have a shower.” Then as he came closer and saw their faces, his own countenance changed and the old look of fear came into his eyes. “Why, what’s the matter—what has happened?” He glanced quickly around, as if half expecting to see some one else near-by.

“Marta ain’t come home,” said Thad.

And in the same instant Bob asked:

“Did she say anythin’ to you about bein’ specially late gettin’ back to-day?”

Edwards drew a long breath of relief.

“No, she said nothing to me about her plans. But really, there is no cause for worry, is there? She always stops at the Burtons’ with the mail on her way back, you know. Perhaps she stayed longer than she realized. Come on in out of the wet,” he added, as the pattering drops of rain grew more plentiful. “She will be along presently, I am sure.”
