The Pine Squirrel is the form found in the Rockies about the Yellowstone

Park. It is a little darker in colour than the Red-squirrel of the East,

but I find no other difference. It has the same aggressive, scolding

propensities, the same love of the pinyons and their product, the same

friends and the same foes, with one possible partial exception in the

list of habits, and that is in its method of storing up mushrooms.

[Illustration]

The pinyons, or nuts of the pinyon pine, are perhaps the most delicious

nuts in all the lap of bountiful dame Nature, from fir belt in the

north to equatorial heat and on to far Fuego. All wild creatures revel

in the pinyons. To the Squirrels they are more than the staff of life;

they are meat and potatoes, bread and honey, pork and beans, bread and

cake, sugar and chocolate, the sum of comfort, and the promise of

continuing joy. But the pinyon does not bear every year; there are off

years, as with other trees, and the Squirrels might be in a bad way if

they had no other supply of food to lay up for the winter.

A season I spent in the Southern Rockies was an off year for pinyons,

and when September came I was shown what the Squirrels do in such an

emergency. All through autumn the slopes of the hills were dotted with

the umbrellas of countless toadstools or mushrooms, representing many

fat and wholesome species. It is well known that while a few of them are

poisonous, a great many are good food. Scientists can find out which is

which only by slow experiment. "Eat them; if you live they are good, if

you die they are poisonous" has been suggested as a certain method. The

Squirrels must have worked this out long ago, for they surely know the

good ones; and all through late summer they are at work gathering them

for winter use in place of the pine-nuts.

[Illustration]

Now if the provident Squirrel stored these up as he does the pinyons, in

holes or underground, they would surely go to mush in a short time and

be lost. He makes no such mistake. He stores them in the forked branches

of trees, where they dry out and remain good until needed; and wisely

puts them high enough up to be out of reach of the Deer and low enough

to avoid being dislodged by the wind.

As you ramble through the Squirrel-frequented woods, you will often come

across a log or stump which is littered over with the scales fresh cut

from a pine cone; sometimes there is a pile of a bushel or more by the

place; you have stumbled on a Squirrel's workshop. Here is where he does

his husking, and the "clear corn" produced is stored away in some

underground granary till It is needed.

The Pine Squirrel loves to nest in a hollow tree, but also builds an

outside nest which at a distance looks like a mass of rubbish. This, on

investigation, turns out to be a convenient warm chamber some six inches

wide and two or three high. It is covered with a waterproof roof of bark

thatch, and entered by a door artfully concealed with layers and fringes

of bark that hide it alike from blood-thirsty foes and piercing winter

blasts.

CHIPMUNKS AND GROUND-SQUIRRELS

The Red-squirrel is safe and happy only when in the tall trees, but his

kinsmen have sought out any and every different environment. One

enormous group of his great grandfather's second cousins have abandoned

tree life altogether. They have settled down like the Dakota farmers, to

be happy on the prairie, where, never having need to get over anything

higher than their own front doorstep, they have lost the last vestige of

power to climb. These are the Ground-squirrels, that in a variety of

forms are a pest in gardens and on farms in most of the country west of

the Mississippi.

Standing between these and the true Squirrels are the elegant Chipmunks,

the prettiest and most popular of all the family. They frequent the

borderland between woods and prairie; they climb, if anything is to be

gained by it, but they know, like the Ground-squirrels, that Mother

Earth is a safer retreat in time of danger than the tallest tree that

ever grew.

THE GROUND-SQUIRREL THAT PLAYS PICKET-PIN

Conspicuous in its teeming numbers in the Yellowstone Park is the

Picket-Pin Ground-squirrel. On every level, dry prairie along the great

river I found it in swarms.

[Illustration]

It looks much like a common Squirrel, but its coat has become more

mud-coloured, and its tail is reduced by long ages of neglect to a mere

vestige of the ancestral banner. It has developed great powers of

burrowing, but it never climbs anything higher than the little mound

that it makes about the door of its home.

The Picket-pin is an interesting and picturesque creature in some ways,

but it has one habit that I cannot quite condone. In this land of sun

and bright blue air, this world of outdoor charm, it comes forth tardily

in late spring, as late sometimes as the first of May, and promptly

retires in mid-August, when blazing summer is on the face of the earth,

and the land is a land of plenty. Down it goes after three and one half

short months, to sleep for eight and a half long ones; and since during

these three and a half months it is above ground only in broad daylight,

this means that for only two months of the year it is active, and the

other ten, four fifths of its life, it passes in a deathlike sleep.

Of course, the Picket-pin might reply that it has probably as many hours

of active life as any of its kind, only it breaks them up into sections,

with long blanks of rest between. Whether this defense is a good one or

not, we have no facts at present to determine.

[Illustration]

It has a fashion of sitting up straight on the doorway mound when it

wishes to take an observation, and the more it is alarmed by the

approach of an enemy the straighter it sits up, pressing its paws tight

to its ribs, so that at a short distance it looks like a picket-pin of

wood; hence the name.

Oftentimes some tenderfoot going in the evening to stake out his horse

and making toward the selected patch of grassy prairie, exclaims, "Good

Luck! here's a picket-pin already driven in." But on leading up his

horse within ten or twelve feet of the pin, it gives a little "_chirr_"

and dives down out of sight. Then the said tenderfoot realizes why the

creature got the name.

The summer of 1897 I spent in the Park about Yancey's and there had

daily chances of seeing the Picket-pin and learning its ways, for the

species was there in thousands on the little prairie about my cabin. I

think I am safe in saying that there were ten families to the acre of

land on all the level prairie in this valley.

CHINK AND THE PICKET-PINS

As already noted in the Coyote chapter, we had in camp that summer the

little dog called Chink. He was just old enough to think himself a

remarkable dog with a future before him. There was hardly anything that

Chink would not attempt, except perhaps keeping still. He was always

trying to do some absurd and impossible thing, or, if he did attempt the

possible, he usually spoiled his best efforts by his way of going about

it. He once spent a whole morning trying to run up a tall, straight,

pine tree in whose branches was a snickering Pine Squirrel.

The darling ambition of his life for some weeks was to catch one of the

Picket-pin Ground-squirrels that swarmed on the prairie about the camp.

Chink had determined to catch one of these Ground-squirrels the very

first day he came into the valley. Of course, he went about it in his

own original way, doing everything wrong end first, as usual. This, his

master said, was due to a streak of Irish in his makeup. So Chink would

begin a most elaborate stalk a quarter of a mile from the

Ground-squirrel. After crawling on his breast from tussock to tussock

for a hundred yards or so, the nervous strain would become too great,

and Chink, getting too much excited to crawl, would rise on his feet and

walk straight toward the Squirrel, which would now be sitting up by its

hole, fully alive to the situation.

After a minute or two of this very open approach, Chink's excitement

would overpower all caution. He would begin running, and at the last,

just as he should have done his finest stalking, he would go bounding

and barking toward the Ground-squirrel, which would sit like a peg of

wood till the proper moment, then dive below with a derisive chirrup,

throwing with its hind feet a lot of sand right into Chink's eager, open

mouth.

Day after day this went on with level sameness, and still Chink did not

give up, although I feel sure he had bushels of sand thrown in his mouth

that summer by the impudent Picket-pins.

[Illustration]

Perseverance, he seemed to believe, must surely win in the end, as

indeed it did. For, one day, he made an unusually elaborate stalk after

an unusually fine big Picket-pin, carried out all his absurd tactics,

finishing with the grand, boisterous charge, and actually caught his

victim; but this time it happened to be a _wooden_ picket-pin. Any one

who doubts that a dog knows when he has made a fool of himself should

have seen Chink that day as he sheepishly sneaked out of sight behind

the tent.

CHIPMUNKS

Every one recognizes as a Chipmunk the lively little creature that, with

striped coat and with tail aloft, dashes across all the roads and

chirrups on all the log piles that line the roads throughout the

timbered portions of the Park. I am sure I have often seen a thousand of

them in a mile of road between the Mammoth Hot Springs and Norris Geyser

Basin. The traveller who makes the entire round of the Park may see a

hundred thousand if he keeps his eyes open. While every one knows them

at once for Chipmunks, it takes a second and more careful glance to show

they are of three totally distinct kinds.

THE GROUND-SQUIRREL THAT PRETENDS IT'S A CHIPMUNK

First, largest, and least common, is the Big Striped Ground-squirrel,

the Golden Ground-squirrel or Say's Ground-squirrel, called

scientifically _Citellus lateralis cinerascens_. This, in spite of its

livery, is not a Chipmunk at all but a Ground-squirrel that is trying

hard to be a Chipmunk. And it makes a good showing so far as manners,

coat and stripes are concerned, but the incontrovertible evidence of its

inner life, as indicated by skull and makeup, tells us plainly that it

is merely a Ground-squirrel, a first cousin to the ignoble Picket-pin.

I found it especially common in the higher parts of the Park. It is

really a mountain species, at home chiefly among the rocks, yet is very

ready to take up its abode under buildings. At the Lake Hotel I saw a

number of them that lived around the back door, and were almost tamed

through the long protection there given them. Like most of these small

rodents, they are supposed to be grain-eaters but they really are

omnivorous, and quite ready to eat flesh and eggs, as well as seeds and

fruit. Warren in his "Mammals of Colorado," tells of having seen one of

these Ground-squirrels kill some young Bluebirds; and adds another

instance of flesh-eating observed in the Yellowstone Park, where he and

two friends, riding along one of the roads, saw a Say Ground-squirrel

demurely squatting on a log, holding in its arms a tiny young Meadow

Mouse, from which it picked the flesh as one might pick corn from a cob.

Meadow Mice are generally considered a nuisance, and the one devoured

probably was of a cantankerous disposition; but just the same it gives

one an unpleasant sensation to think of this elegant little creature, in

appearance, innocence personified, wearing all the insignia of a

grain-eater, yet ruthlessly indulging in such a bloody and cannibal

feast.

A FOUR-LEGGED BIRD--THE NORTHERN CHIPMUNK

The early naturalists who first made the acquaintance of the Eastern

Ground-squirrel named it Tamias or "The Steward." Later the Northern

Chipmunk was discovered and it was found to be more of a Chipmunk than

its Eastern cousin. The new one had all the specialties of the old kind,

but in a higher degree. So they named this one _Eutamias_, which means

"good" or "extra good" Chipmunk. And extra good this exquisite little

creature surely is in all that goes to make a charming, graceful, birdy,

pert and vivacious four-foot. In everything but colours it is Eutamias

or Tamias of a more intensified type. Its tail is long in proportion and

carried differently, being commonly held straight up, so that the

general impression one gets is of a huge tail with a tiny striped animal

attached to its lower end.

[Illustration]

Its excessive numbers along the roads in the Park are due to two things:

First, the food, for oats are continually spilled from the freighting

wagons. Second, the protection of piles of pine trees cut and cast aside

in clearing the roadway.

There is one habit of the Eastern Chipmunk that I have not noted in the

mountain species, and that is the habit of song. In the early spring and

late autumn when the days are bright and invigorating, the Eastern

Chipmunk will mount some log, stump or other perch and express his

exuberant joy in a song which is a rapid repetition of a bird-like note

suggested by "Chuck," "Chuck," or "Chock," "Chock." This is kept up two

or three minutes without interruption, and is one of those delightful

woodland songs whose charm comes rather from association than from its

inherent music.

If our Western Chipmunk is as far ahead in matters musical as he is in

form and other habits, I shall expect him to render no less than the

song of a nightingale when he gives himself up to express his wild

exuberance in a chant.

I shall never forget the days I spent with a naturalist friend in an old

mill building in western Manitoba. It was in a pine woods which was

peopled with these little Chipmunks. They had hailed the mill and its

wood piles, and especially the stables, with their squandered oats, as

the very gifts of a beneficient Providence for their use and benefit.

They had concentrated on the mill; they were there in hundreds, almost

thousands, and whenever one looked across the yard in sunny hours one

could see a dozen or more together.

The old mill was infested with them as an old brewery with rats. But in

many respects besides beauty they were an improvement on rats: they did

not smell, they were not vicious, and they did not move by night.

[Illustration]

During the daytime they were everywhere and into everything. Our slender

stock of provisions was badly reduced when, by mischance, the tin box

was left open a few hours, but we loved to see so much beautiful life

about and so forgave them. One of our regular pleasures was to sit back

after a meal and watch these pert-eyed, four-legged birds scramble onto

the table, eat the scraps and lick all the plates and platters clean.

Like all the Chipmunks and Ground-squirrels, this animal has

well-developed cheek-pouches which it uses for carrying home seeds and

roots which serve for food in the winter. Or perhaps we should say in

the early spring, for the Chipmunk, like the Ground-squirrel, goes into

the ground for a long repose as soon as winter comes down hard and

white.

Yet it does not go so early or stay so late as its big cousin. October

still sees it active, even running about in the snow. As late as October

31st at Breckenridge, Col., I saw one sitting up on a log and eating

some grass or seeds during a driving snowstorm. High up in the

Shoshonees, after winter had settled down, on October 8, 1898, I saw one

of these bright creatures bounding through the snow. On a stone he

paused to watch me and I made a hasty sketch of his attitude.

[Illustration]

Then, again, it is out in the spring, early in April, so that it is

above ground for at least seven months of the year. Its nest is in a

chamber at the end of a long tunnel that it digs under ground, usually

among roots that make hard digging for the creatures that would rout

them out. Very little is known as yet, however, about the growth or

development of the young, so here is an opportunity for the young

naturalist who would contribute something to our knowledge of this

interesting creature.

A STRIPED PIGMY--THE LEAST CHIPMUNK

Closely akin to this one and commonly mistaken for its young, is the

Least Chipmunk (_Eutamias minimus_), which is widely diffused in the

great dry central region of the Continent. Although so generally found

and so visible when found, its history is practically unknown. It

probably lives much like its relatives, raising a brood of four to six

young in a warm chamber far underground, and brings them up to eat all

manner of seeds, grains, fruits, herbs, berries, insects, birds, eggs,

and even mice, just as do most of its kinsmen, but no one has proved any

of these things. Any exact observations you may make are sure to be

acceptable contributions to science.

The Rabbits and their Habits

The Rabbits and their Habits

[Illustration]

If the Wolf may be justly proud of his jaws and the Antelope of his

legs, I am sure that the Rabbit should very properly glory in his

matchless fecundity. To perfect this power he has consecrated all the

splendid energies of his vigorous frame, and he has magnified his

specialty into a success that is worth more to his race than could be

any other single gift.

[Illustration]

Rabbits are without weapons of defense, and are simple-minded to the

last degree. Most are incapable of long-distance speed, but all have an

exuberance of multiplication that fills their ranks as fast as foe can

thin the line. If, indeed, they did not have several families, several

times a year, they would have died out several epochs back.

[Illustration]

There are three marked types of Rabbits in the Rockies--the Cottontail,

the Snowshoe, and the Jackrabbit. All of them are represented on the

Yellowstone, besides the little Coney of the rocks which is a remote

second cousin of the family.

MOLLY COTTONTAIL, THE CLEVER FREEZER

[Illustration: Molly Freezing]

I have often had occasion to comment on the "freezing" of animals. When

they are suddenly aware of a near enemy or confronted by unexpected

situations, their habit is to _freeze_--that is, become perfectly rigid,

and remain so until the danger is past or at least comprehended.

Molly Cottontail is one of the best "freezers." Whenever she does not

know what to do, she does nothing, obeying the old Western rule, "Never

rush when you are rattled." Now Molly is a very nervous creature. Any

loud, sharp noise is liable to upset her, and feeling herself unnerved

she is very apt to stop and simply "freeze." Keep this in mind when next

you meet a Cottontail, and get a photograph.

In July, 1902, I tried it myself. I was camped with a lot of Sioux

Indians on the banks of the Cheyenne River in Dakota. They had their

families with them, and about sundown one of the boys ran into the tepee

for a gun, and then fired into the grass. His little brother gave a

war-whoop that their "pa" might well have been proud of, then rushed

forward and held up a fat Cottontail, kicking her last kick. Another, a

smaller Cottontail, was found not far away, and half a dozen young

redskins armed with sticks crawled up, then suddenly let them fly. Bunny

was hit, knocked over, and before he could recover, a dog had him.

[Illustration]

I had been some distance away. On hearing the uproar I came back toward

my own campfire, and as I did so, my Indian guide pointed to a

Cottontail twenty feet away gazing toward the boys. The guide picked up

a stick of firewood.

The boys saw him, and knowing that another Rabbit was there they came

running. Now I thought they had enough game for supper and did not wish

them to kill poor Molly. But I knew I could not stop them by saying

that, so I said: "Hold on till I make a photo." Some of them understood;

at any rate, my guide did, and all held back as I crawled toward the

Rabbit. She took alarm and was bounding away when I gave a shrill

whistle which turned her into a "frozen" statue. Then I came near and

snapped the camera. The Indian boys now closed in and were going to

throw, but I cried out: "Hold on! not yet; I want another." So I chased

Bunny twenty or thirty yards, then gave another shrill whistle, and got

a fourth snap. Again I had to hold the boys back by "wanting another

picture." Five times I did this, taking five pictures, and all the while

steering Molly toward a great pile of drift logs by the river. I had now

used up all my films.

The boys were getting impatient. So I addressed the Cottontail solemnly

and gently: "Bunny, I have done my best for you. I cannot hold these

little savages any longer. You see that pile of logs over there? Well,

Bunny, you have just five seconds to get into that wood-pile. Now git!"

and I shooed and clapped my hands, and all the young Indians yelled and

hurled their clubs, the dogs came bounding and Molly fairly dusted the

earth.

"Go it, Molly!"

"Go it, dogs!"

"Ki-yi, Injuns!"

The clubs flew and rattled around her, but Molly put in ten feet to the

hop and ten hops to the second (almost), and before the chase was well

begun it was over; her cotton tuft disappeared under a log; she was safe

in the pile of wood, where so far as I know she lived happy ever after.

[Illustration]

THE RABBIT THAT WEARS SNOWSHOES

The Snowshoe Rabbit is found in all parts of the Park, though not in

very great numbers. It is called "Snowshoe" on account of the size of

its feet, which, already large, are in snow time made larger by fringes

of stiff bristles that give the creature such a broad area of support

that it can skip on the surface of soft snow while all its kinsmen sink

in helplessness.

[Illustration]

Here is the hind foot of a Snowshoe in winter, contrasted with the hind

foot of a Jackrabbit that was nearly three times its weight.

Rabbits are low in the scale of intelligence, but they are high enough

to have some joy in social life. It always gives one a special thrill of

satisfaction when favoured with a little glimpse into the home ways, the

games, or social life of an animal; and the peep I had into the Rabbit

world one night, though but a small affair, I have always remembered

with pleasure, and hope for a second similar chance.

This took place in the Bitterroot Mountains in Idaho, in 1902. My wife

and I were out on a pack-train trip with two New York friends. We had

seen some rough country in Colorado and Wyoming, but we soon agreed that

the Bitterroots were the roughest of all the mountains. It took

twenty-eight horses to carry the stuff, for which eighteen were enough

in the more southern Rockies.

[Illustration]

The trails were so crooked and hidden in thick woods, that sometimes

the man at the rear might ride the whole day, and never see all the

horses until we stopped again for the night.

THE TERROR OF THE MOUNTAIN TRAILS

[Illustration]

There were other annoyances, and among them a particularly dangerous

animal. The country was fairly stocked with Moose, Elk, Blacktail,

Sheep, Goats, Badgers, Skunks, Wolverines, Foxes, Coyotes, Mountain

Lions, Lynx, Wolves, Black Bears and Grizzly Bears, but it was none of

these that inspired us with fear. The deadly, dangerous creature, the

worst of all, was the common Yellow-Jacket-Wasp. These Wasps abounded in

the region. Their nests were so plentiful that many were on, or by, the

narrow crooked trails that we must follow. Generally these trails were

along the mountain shoulder with a steep bank on the upside, and a sheer

drop on the other. It was at just such dangerous places that we seemed

most often to find the Yellow-Jackets at home. Roused by the noise and

trampling, they would assail the horses in swarms, and then there would

be a stampede of bucking, squealing, tortured animals. Some would be

forced off the trail, and, as has often happened elsewhere, dashed to

their death below. This was the daily danger.

[Illustration]

One morning late in September we left camp about eight, and set off in

the usual line, the chief guide leading and the rest of us distributed

at intervals among the pack-horses, as a control. Near the rear was the

cook, after him a pack-horse with tins and dishes, and last of all

myself.
