“Wau-nan-gee die for him,” said the youth energetically, as, after again pressing the extended hand of the Virginian, he traced his way cautiously to the encampment.

“Mr. Ronayne,” repeated Captain Headley, “where are you?”

“Here, sir; I have for a few moments been absent from my post, but I thought I remarked an Indian skulking near to watch our movements, and I followed him. I was not wrong; it was Pee-to-tum. When discovered, he rose to his feet and would have stabbed me, but Wau-nan-gee was near and warded off the blow.”

“Wau-nan-gee! said you, Mr. Ronayne? Did he ward off the blow aimed at your life?”

“He did, sir; why should he not? We have always been friends.”

Had it not been dark, Captain Headley would have looked as he felt, exceedingly puzzled for a reply.

“To tell the truth, Mr. Ronayne, I had not suspected this. I should rather have imagined that he was the chief instigator of the young men to discontent; but I am glad to find it otherwise.”

For a moment it flashed across the mind of the Virginian that Mrs. Headley had, from policy or in confidence, communicated all she knew in regard to Maria's evasion to her husband. The idea of any man possessing the slightest knowledge of wrong in his wife would have maddened him; but now that he in some measure knew the facts, and looked upon her in all the purity of her spotless nature, he was not sorry to have an opportunity to remove the impression; he, therefore, answered calmly, yet without adverting to the actual position of his wife.

“So far from that being the case, Captain Headley, Wau-nan-gee is the last person to engage in an outrage of the kind. Doubtless these letters, of which the youth has been the bearer, will explain much that is now a mystery.”

The laborious duty of the night being now ended, the gates were once more fastened; and as the officers passed the lamp which hung over the entrance of the commandant's quarters, Ronayne glanced at the superscriptions of the two missives. The one was written in ink, and directed to Mrs. Headley; the other in pencil, and addressed to himself.
