Black Oxen by Gertrude Atherton

Clavering had tied the boat to a tree in a little inlet far down the lake, and they were walking through a wood of spruce trees and balsam. There was no leafy curtain here, although they could see one swaying on either side through open vistas between the rigid columns of the spruce. A trail was hardly necessary for there was no undergrowth, and although the trees were set close together they were easily circumnavigated.

It was some time since they had spoken. His face was graver than she had ever seen it, and she waited for him to speak. She almost could feel those unuttered words beating on the silence of the woods. There was nothing else to break that silence but the faint constant murmur in the tree-tops, and once, beyond that leafy curtain, the sudden trilling of a solitary bird. Again, the tremendousness of this high isolation swept over her. The camp and its gay party might have been on some far distant lake.
