It was quite exciting to follow that little Weasel's trail in the snow. I came to where he had startled a moor-hen and to where he had startled a rook, and to where he had had a splendid game chasing mice. I am showing you a picture of this, and you will notice at once the line down the centre of one of the tracks, which is made by Mousey's tail. Another of the pictures shows you two mouse-tracks running to separate mouse-holes, which I was very glad to know about, and which I don't think I should ever have seen but for the tell-tale snow. A Rat's track is much the same, only larger; and a Stoat's track is the same as a Weasel's, only larger. A Hedgehog does not often come out in the snow, but he does sometimes and leaves a very smudgy track behind him, for he drags his fur along the ground. [Illustration: WHERE THE WEASEL MET THE ROOK You can see where the Rook's wing hit the snow] Snow shows one much more than mud, but, unless it is of just the right softness the prints in it are apt to be splodgy, and I don't think you ever get so perfect a track in snow as you sometimes do in mud. The pictures of the Vixen's and the Otter's footprints will show you what I mean. A Vixen's footprints are smaller than a Fox's, and a Fox's footprints are smaller than most people think, indeed a Fox is a smaller animal than most people think. I have a little wire-haired terrier whose footprints are much larger than those of a Vixen. At the same time it is not very easy to distinguish a Fox's track from that of a small dog. Generally a Dog's claws make their mark as well as the pads, and this does not often happen with the Fox; but I think a better way of telling the difference is to remember that a Fox's pads are more oval-shaped than a Dog's. You will always, I think, be able to tell an Otter's footprints (some people call them the Otter's seal) by their size, and by their leading to or from the water. Usually the claws can be clearly traced and sometimes the webbing of the feet as well. I have never seen clean-cut Badger's footprints--all I have met with have been very broad and splodgy, more smears than patterns--and I have never seen a Marten's trail at all. [Illustration: TWO MOUSE TRAILS LEADING TO HOLES IN THE SNOW] [Illustration: THE FOX'S FOOTPRINTS] Footprints tell us a good deal of what is going on about us, and so do "runs" in the grass, and "runs" in the hedges. But, of course, there are other things to be looked for. Often one finds the remains of beasties' meals, nuts for instance. Nuts with clean-cut round holes in them have been gnawed by Dormice, nuts with jagged holes by Red Meadow Mice and Wood Mice, nuts split clean in half most likely by Squirrels. Otters leave half-eaten fish about sometimes, and scattered broken eggshells tell you where Stoats have been running the hedgerow. If you notice where you find these things and keep your eyes open, you are sure in time to see what you are looking for. [Illustration]
