Although I have known the Pack-rat for years in the mountains, I never saw one within the strict lines of the Yellowstone sanctuary. But the guides all assure me that they are found and manifest the same disposition here as elsewhere. So that if you should lose sundry bright things around camp, or some morning find your boots stuffed with pebbles, deer sign, or thorns, do not turn peevish or charge the guide with folly; it means, simply, you have been visited by a Mountain Rat, and any uneatables you miss will doubtless be found in his museum, which will be discovered within a hundred yards—a mass of sticks and rubbish under a tree—with some bright and shiny things on the top where the owner can sit amongst them on sunny days, and gloat till his little black eyes are a-swim, and his small heart filled with holy joy.
THE UPHEAVER—THE MOLE-GOPHER
As you cross any of the level, well-grassed prairie regions in the Yellowstone you will see piles of soft earth thrown up in little hillocks, sometimes a score or more of them bunched together. The drivers will tell you that these are molehills, which isn't quite true. For the Mole is a creature unknown in the Park, and the animal that makes these mounds is exceedingly abundant. It is the common Mole-gopher, a gopher related very distantly to the Prairie-dog and Mountain Whistler, but living the underground life of a Mole, though not even in the same order as that interesting miner, for the Mole-gopher is a rodent (Order Rodentia) and the Mole a bug-eater (Order Insectivora); just as different as Lion and Caribou.
The Mole-gopher is about the size of a rat, but has a short tail and relatively immense forepaws and claws. It is indeed wonderfully developed as a digger.
Examine the mound of earth thrown up. If it is a fair example, it will make fully half a bushel. Next count the mounds that are within a radius of fifty paces; probably all are the work of this Gopher, or rather this pair, for they believe in team play.
Search over the ground carefully, and you will discern that there are scores of ancient mounds flattened by the weather, and traces of hundreds, perhaps, that date from remote years.
Now multiply the size of one mound by the number of mounds, and you will have some idea of the work done by this pair. Finally, remembering that there may be a pair of Gophers for every acre in the Park, estimate the tons of earth moved by one pair and multiply it by the acres in the Park, and you will get an idea of the work done by those energetic rodents as a body, and you will realize how well he has won his Indian name, the "Upheaver."
We are accustomed to talk of upheaval in geology as a frightful upset of all nature, but here before our eyes is going on an upheaval of enormous extent and importance, but so gently and pleasantly done that we enjoy every phase of the process.

FOX, MARTEN, BEAVER, AND OTTER
Fair Lady Multo Millionaire riding in the dusty stagecoach, comparing as you go the canyons of the Yellowstone with memories of Colorado, Overland, and Stalheim, you, in your winter home, know all about fur as it enters your world with its beauty, its warmth, its price—its gauge of the wearer's pocket. Let me add a segment of the circle to round your knowledge out.
When nature peopled with our four-foot kin the cold north lands, it was necessary to clothe these little brethren of ours in a coat that should be absolutely warm, light, durable, of protective colour, thick in cold weather, thin in warm. Under these conditions she produced fur, with its densely woolly undercoat and its long, soft, shining outer coat, one for warmth, the other for wet and wear. Some northern animals can store up food in holes or in the fat of their bodies, so need not be out when the intensest cold is on the land. Some have to face the weather all winter, and in these we find the fur of its best quality. Of this class are the Marten and the Northern Fox. They are the finest, warmest, lightest, softest of all furs. But colour is a cardinal point when beauty is considered and where fashion is Queen. So the choicest colours are the soft olive brown with silver hairs, found in the Russian Sable, and the glossy black with silver hairs, found in the true Silver Fox of the North.
THE MOST WONDERFUL FUR IN THE WORLD
What is the Silver Fox? Simply a black freak, a brunette born into a red-headed family. But this does not cast any reflection on the mother or on father's lineage. On the contrary, it means that they had in them an element of exceptional vigour, which resulted in a peculiar intensifying of all pigments, transmuting red into black and carrying with it an unusual vigour of growth and fineness of texture, producing, in short, the world-famed Silver Fox, the lightest, softest, thickest, warmest, and most lustrous of furs, the fur worth many times its weight in gold, and with this single fault, that it does not stand long wear.
Cold and exposure are wonderful stimulants of the skin, and so it is not surprising that the real Silver Fox should appear only in very cold climates. Owing to its elevation the Yellowstone Park has the winter climate of northern Canada, and, as might have been predicted, the Silver Fox occurs among the many red-headed or bleached blonde Foxes that abound in the half open country.
You may travel all round the stage route and neither see nor hear a Fox, but travel quietly on foot, or better, camp out, and you will soon discover the crafty one in yellow, or, rather, he will discover you. How? Usually after you have camped for the night and are sitting quietly by the fire before the hour of sleep, a curious squall is heard from the dark hillside or bushes, a squall followed by a bark like that of a toy terrier. Sometimes it keeps on at intervals for five minutes, and sometimes it is answered by a similar noise. This is the bark of a Fox. It differs from the Coyote call in being very short, very squally, much higher pitched, and without any barks in it that would do credit to a fair-sized dog. It
