As I watched the cub curled up in a woolly ball, I wanted to creep up and stroke his soft fur. Leaving the hard path, I started to cover as silently as possible the fifty feet that lay between us. Before I had gone far, a leaf rustled underfoot, and in a second the cub was on his feet, wide awake, and staring down at me. With one foot in the air, I waited and waited until he settled down to sleep again. A minute later the same thing happened once more, only to be repeated at every step or so. It took me something like half an hour to reach a point within twenty feet of where he lay, and I looked straight into his eyes each time that he stood up. No wild animal can tell a man from a tree by sight alone if only he stands still. Suddenly, as the cub sprang up, perhaps for the tenth time, there about six feet to one side of him stood the old mother fox. I had not heard a sound or seen a movement, but there she was. I was so close that I dared not move my head to look at the cub, but turned only my eyes. When I looked back the mother fox was gone. With no sudden movement that I could detect, there almost before my eyes she had melted into the landscape. I stood like a stone until the cub had lain down once more. This time evidently he was watching me out of his wrinkled-up little eyes, for at my very first forward movement he got up, and with no appearance of haste turned around and disappeared down in the burrow. The watch-tower log was vacant, although I have no doubt that the mother fox was watching me from some unseen spot. When I came to examine the den, I found that there were three burrows in a line, perhaps fifteen feet in length, with a hard-worn path leading from one to the other. The watch-log behind them was rubbed smooth and shiny, with reddish fox-hairs caught in every crevice. Near the three burrows was a tiny one, which I think was probably dug as an air-hole; while in front I found the feathers of a flicker, a purple grackle, and a chicken, besides the remains of the crow aforesaid. How any fox outside of the fable could beguile a crow is a puzzle to me. All of these burrows were in plain sight, and I hunted a long time to find the concealed one which is a part of the home of every well-regulated fox family. For a while I could find no trace of it. Finally I saw on the side of a stump one reddish hair that gave me a clue. Examining the stump carefully, I found that it was hollow and formed the entrance to the secret exit from the three main burrows. A week later I went again to look at the home of that fox family; but it was deserted by them and was now tenanted by a fat woodchuck, who would never have ventured near the den if the owners had not left it. Mrs. Fox had evidently feared the worst from my visit, and in the night had moved her whole family to some better-hidden home. This was three years ago, and, although I visit the place every winter, no tell-tale tracks ever show that she has moved back.
