Mercedes had disappeared when she reached the spot of the accident, but Irene was tugging desperately at the huge windlass, slowly winding up the heavy bucket, moaning all the while in a distracted undertone, while tears of fright trickled down her dirty face. So busy was she that she never heard the patter of Tabitha's feet behind her, and the first intimation she had of help at hand was when the older girl jerked her back from the mouth of the shaft, released the half-raised bucket, and sent it hurtling back into the pit once more.

"Go for the assayer," she commanded hoarsely, seizing the heavy rope with both hands, and preparing to descend as Toady had done. "Run, hurry! And then get Dr. Hayes. We may need him."

The windlass creaked and groaned, the rope swayed and strained, as Tabitha slid out of sight, while Irene raced madly away to do her bidding. Unmindful of bumps or bruises, and almost unaware that her hands were cruelly burned and torn from her too rapid descent, the black-eyed girl had scarcely touched the bottom of the shaft before she had her lantern lighted and was digging like mad at the fallen rock and debris which almost completely blocked the entrance of the narrow cross-cut.

"Who is it?" called a voice from behind the barrier.

"Thank God!" breathed Tabitha, working with renewed fury. "That you, Toady?"

"Bet you!" came the cheering response.

"Are you hurt?"

"Nope!"

"Where are the others?"

"Here!"
