“It's too fur fur me, too, an' my eyes are good, but ten or fifteen minutes ago, leftenant, I thought I saw a shadder at the edge of the grove. It 'peared to me that the shadder was like that of a horse with a man on it. After a while it went back among the trees an' o' course I lost it thar.”

“You feel quite sure you saw the shadow, Seth?”

“Yes, leftenant. I'm shore I ain't mistook. I've hunted 'coons an' 'possums at night too much to be mistook about shadders. I reckon, if I may say so, shadders is my specialty, me bein' somethin' o' a night owl. As shore as I'm standin' here, leftenant, and as shore as you're settin' there on your hoss, a mounted man come to the edge of that wood an' stayed thar a while, watchin' us. I'd have follered him, but I couldn't leave my beat here, an' you're the first officer I've saw since. It may amount to nothin, an' then again it mayn't.”

“I'm glad you told me. I'll go into the grove myself and see if anybody is there now.”

“Leftenant, if I was you I'd be mighty keerful. If it's a spy it'll be easy enough for him under the cover of the trees to shoot you in the open comin' toward him.”

Harry knew that Jackson planned a surprise of some kind and Seth Moore's words about the mounted man alarmed him. He did not doubt the accuracy of the young mountaineer's eyesight, or his coolness, and he resolved that he would not go back to headquarters until he knew more about that “shadow.” But Moore's advice about caution was not to be unheeded.

“If you keep in the edge of our woods here,” said Moore, “an' ride along a piece you'll come to a little valley. Then you kin go up that an' come into the grove over thar without being seed.”

“Good advice. I'll take it.”

Harry loosened one of the pistols in his belt and rode cautiously through the wood as Seth Moore had suggested. The ground sloped rapidly, and soon he reached the narrow but deep little valley with a dense growth of trees and underbrush on either side. The valley led upward, and he came into the grove just as Moore had predicted.

This forest was of much wider extent than he had supposed. It stretched northward further than he could see, and, although it was devoid of undergrowth, it was very dark among the trees. He rode his horse behind the trunk of a great oak, and, pausing there, examined all the forest within eyeshot.
