It is always worth while to cultivate the old guides. Young guides are often fresh and shallow, but the quiet old fellows, that have spent their lives in the mountains, must be good or they could not stay in the business; and they have seen so much and been so far that they are like rare old manuscript volumes, difficult to read, but unique and full of value. It is not easy to get them to talk, but there is a combination that often does it. First, show yourself worthy of their respect by holding up your end, be it in an all-day climb or breakneck ride; then at night, after the others have gone to bed, you sit while the old guide smokes, and by a few brief questions and full attention, show that you value any observations he may choose to make. Many happy hours and much important information have been my reward for just such cautious play, and often as we sat, there flitted past, in the dim light, the silent shadowy forms of the campfire ghosts. Swift, not twinkling, but looming light and fading, absolutely silent. Sometimes approaching so near that the still watcher can get the glint of beady eyes or even of a snowy breast, for these ghosts are merely the common Mice of the mountains, abounding in every part of the West.
There are half a dozen different kinds, yet most travellers will be inclined to bunch them all, and pass them by as mere Mice. But they are worthy of better treatment. Three, at least, are so different in form and ways that you should remember them by their names.
First is the Whitefooted or Deer-mouse. This is the one that you find in the coffee pot or the water bucket in the morning; this is the one that skips out of the "grub box" when the cook begins breakfast; and this is the one that runs over your face with its cold feet as you sleep nights. It is one of the most widely diffused mammals in North America to-day, and probably the most numerous.
It is an elegant little creature, with large, lustrous black eyes like those of a Deer, a fact which, combined with its large ears, the fawn-coloured back, and the pure white breast, has given it the name of "Deer-mouse." It is noted for drumming with one foot as a call to its mate, and for uttering a succession of squeaks and trills that serve it as a song.
Sometimes its nest is underground; and sometimes in a tree, whence the name Tree-mouse. It breeds several times in a year and does not hibernate, so is compelled to lay up stores of food for winter use. To help it in doing this it has a very convenient pair of capacious pockets, one in each cheek, opening into the mouth.
He glides around the fire much as the others do, but at the approach of danger, he simply fires himself out of a catapult, afar into the night. Eight or ten feet he can cover in one of these bounds and he can, and does, repeat them as often as necessary. How he avoids knocking out his own brains in his travels I have not been able to understand.
This is the New World counterpart of the Jerboa, so familiar in our school books as a sort of diminutive but glorified kangaroo that frequents the great Pyramids. It is so like a Jerboa in build and behaviour that I was greatly surprised and gratified to find my scientist friends quite willing that I should style it the American representative of the African group.
The country folk in the East will tell you that there are "seven sleepers" in our woods, and enumerate them thus: the Bear, the Coon, the Skunk, the Woodchuck, the Chipmunk, the Bat, and the Jumping Mouse. All are good examples, but the longest, soundest sleeper of the whole somnolent brotherhood is the Jumping Mouse. Weeks before summer is ended it has prepared a warm nest deep underground, beyond the reach of cold or rain, and before the early frost has nipped the aster, the Jumping Mouse and his wife curl up with their long tails around themselves like cords on a spool, and sleep the deadest kind of a dead sleep, unbroken by even a snore, until summer is again in the land, and frost and snow unknown. This means at least seven months on the Yellowstone.
Since the creature is chiefly nocturnal, the traveller is not likely to see it, excepting late at night when venturesome individuals often come creeping about the campfire, looking for scraps or crumbs; or sometimes other reckless youngsters of the race, going forth to seek their fortunes, are found drowned in the tanks or wells about the hotels.

Here is a diagram of a Jumper in the act of living up to its reputation. And at once one asks what is the reason for this interminable tail. The answer is, it is the tail to the kite, the feathering to the arrow; and observation shows that a Jumping Mouse that has lost its tail is almost helpless to escape from danger. A good naturalist records that one individual that was de-tailed by a mowing machine, jumped frantically and far, but had no control of the direction, and just as often as not went straight up or landed wrong end to, and sometimes on a second bound was back where it had started from.
It is very safe to say that all unusual developments serve a very vital purpose in the life of the creature, but we are not always so fortunate as in this case, to know what that purpose is.
One day fifteen years ago I was sitting on a low bank near Baronett's Bridge across the Yellowstone, a mile and a half from Yancey's. The bank was in an open place, remote from cliffs or thick woods; it was high, dry, and dotted with holes of rather larger than field-mouse size, which were further peculiar in that most of them went straight down and none was connected with any visible overland runways.
All of which is secondary to the fact that I was led to the bank by a peculiar bleating noise like the "weak" of a Calling Hare, but higher pitched.
As I passed the place the squeakers were left behind me, and so at last I traced the noise to some creature underground. But what it was I could not see or determine. I knew only from the size of the hole it must be as small as a Mouse.
Not far away from this I drew some tracks I found in the dust, and later when I showed the drawing, and told the story to a naturalist friend, he said: "I had the same experience in that country once, and was puzzled until I found out by keeping a captive that the creature in the bank was a Grasshopper Mouse or a Calling Mouse, and those in your drawing are its tracks."
At one time it was considered an extremely rare animal, but now, having discovered its range, we know it to be quite abundant. In northern New Mexico I found one species so common in the corn-field that I could catch two or three every night with a few mousetraps. But it is scarce on the Yellowstone, and all my attempts to trap it were frustrated by the much more abundant Deer-mice, which sprang the bait and sacrificed themselves, every time I tried for the Squeaker.
In the fall of 1912 I was staying at Standing Rock Agency in North Dakota. On the broken ground, between the river and the high level prairie, I noted a ridge with holes exactly like those I had seen on the Yellowstone. A faint squeak underground gave additional and corroborative evidence. So I set a trap and next night had a specimen of the Squeaker as well as a couple of the omnipresent Deer-mice.
Doubtless the Calling Mouse has an interesting and peculiar life history, but little is known of it except that it dwells on the dry plains, is a caller by habit;—through not around the campfire—it feeds largely on grasshoppers, and is in mortal terror of ants.
