CHAPTER XIV

MEADOW-MICE [3]—HAMSTERS—DORMICE

“Another kind of rodent now calls for our attention: it is the family

of meadow-mice, commonly confounded with rats. Meadow-mice are easily

recognized by their short, slightly hairy tail.

“The meadow-mouse is about as large as a common mouse. Its coat is of a

yellowish hue mixed with gray above and dirty white underneath. The

tail is only one-quarter as long as the body. The eyes are large and

prominent, the ears rounded, hairy, and standing out but little from

the fur. The head is large and less pointed than that of the ordinary

mouse.

“In its rapid and abundant breeding the meadow-mouse is one of the

farmer’s chief foes. It overruns grain-fields especially, cutting down

the stalks to nibble the ears. After harvest it attacks clover roots,

carrots, potatoes, and the products in general of our kitchen-gardens.

In winter it digs under the furrows to eat the seeds sown there. If the

soil is so frost-bound as not to permit it to reach the buried seed, it

retires to the stacks of grain, where it does great damage. It never

makes its way into our dwellings. Meadow-mice appear to emigrate from

one country to another in colonies when the country they have ravaged

can no longer supply them with food; at any rate, from time to time,

once or twice in a decade, they suddenly appear in countless droves

that are a real scourge to the country visited. The best destroyers of

these creatures are nocturnal birds of prey, as is proved by the

presence of their skulls, bones, and skins in the balls that are thrown

up by these birds after digestion. Some say diurnal birds of prey,

buzzards in particular, are equally fond of them. It is not at all

uncommon to find in a buzzard’s crop as many as ten or more

meadow-mice.

“The underground meadow-mouse is much less common in France than the

one just described, from which it differs in its gray-and-blackish

coat, its somewhat smaller tail, and its tiny eyes. But the greatest

difference is in its habits. The first-mentioned lives in the fields,

especially in grain-fields, while the second frequents meadows and

kitchen-gardens. It feeds on various kinds of vegetables, such as

celery, artichokes, carrots, potatoes, and cardoons. It seldom shows

itself out of its underground tunnels, and on account of its habit of

lurking beneath the surface it is called the underground meadow-mouse.

“The amphibian meadow-mouse is commonly known by the name of water-rat.

We can easily tell it from the black rat, which is of about the same

size, by its red coat, its short tail (which is not quite half the

length of its body), and its larger and less pointed head. It burrows

under the banks of streams, ditches, and marshes, where it feeds

chiefly on roots, but does not disdain small fish when it can catch

them. It is a good swimmer and diver. Sometimes it makes its way into

kitchen-gardens, where it does the same sort of harm as the underground

meadow-mouse, and into orchards, where it gnaws the base of young

trees.

“The lemming is never seen around here. It frequents the coasts of the

Arctic Ocean in Norway and Lapland. I will tell you something about it

on account of its curious way of traveling from one country to another,

of which our meadow-mouse offers us a far less striking example. The

lemming, with its very short and hairy tail, its big head, and its

stocky body, has the appearance of a small rabbit. Its coat is red

marbled with black and brown.

“At the approach of severe cold weather, and sometimes with no apparent

reason, the lemmings leave their haunts in the high mountain chains of

Norway and set out on a long journey toward the sea. The emigrating

horde, composed of myriads of individuals, trot in a straight line over

all obstacles, never allowing themselves to be turned from their

course. In traveling in a line, one after another, says Linnæus, the

great Swedish naturalist, they trace straight parallel furrows, two or

three fingers deep and several ells apart. They devour everything

eatable that obstructs their passage, all roots and herbage. Nothing

turns them from their course. Let a man appear in their path, and they

slip between his legs. If they come to a haystack they gnaw a tunnel

through it; reaching a rock, they skirt it in a semicircle and then

resume their original direction. Should a lake be encountered on their

route, they swim across it in a straight line, however wide it may be.

If a boat is in their way in the middle of a body of water, they

clamber over it and jump into the water again on the other side. A

swiftly flowing river does not stop them: they plunge into the foaming

current even if they all perish.”

“They must be very obstinate,” said Emile, “to prefer to drown rather

than turn their procession out of a straight line.”

“Animals sometimes show these examples of obstinacy, which we cannot

understand, but which might easily be explained if we knew the motives

that make them act thus. Perhaps by deviating from a straight line the

lemmings might lose their way, a way provided with no finger-posts, but

indicated simply by instinct. However, we will leave them to pursue

their long pilgrimage, from which few will return, so numerous are the

dangers and the enemies awaiting them on the way. Let them cross their

rivers and lakes while we return to the rodents of France.

“The hamster abounds in central Europe, notably in Alsace. It is also

called the Strasbourg marmot or rye pig. It is almost as large as the

black rat, but is more stocky. Its tail is short and hairy, its fur red

on the back, black under the belly, with yellowish spots on the flanks,

a white spot on the throat, and another on each shoulder.

“Hamsters live on roots, fruit, and especially cereals, of which they

store up a large supply. Each animal digs a burrow composed of several

rooms, the largest of which is used as a granary. There they store rye

and wheat, beans and peas, vetch and linseed. The hamster hoards like a

miser, laying up far more than it will ever need, simply for the

satisfaction of hoarding. In some of its store-rooms as much as two

hundredweight of provisions may be found. What can a creature no bigger

than your fist do with all these supplies? Winter comes, and the

hamster shuts itself up in its underground quarters, assured of food

and lodging, and grows big and fat. If the cold is very severe it goes

to sleep like the marmot.”

“And what about the two hundredweight of grain collected, a kernel at a

time?” queried Emile.

“The whole supply simply spoils and is so much waste; but little does

the hamster care; he begins all over again the next year. The animal’s

special business is, first and foremost, to ravage fields, as is proved

by the pile of grain it stores up, out of all proportion to its needs.

It hoards food to destroy it, far more than to be sure of something to

eat, being very different in this way from most hibernating animals. In

the midst of all its stores of food, if the winter is very cold, it is

overtaken by the same torpor that saves the hedgehog and the bat from

death by starvation. This miser has not even the excuse of want. Happy

are those regions that it does not rob! Let us pass on to other

rodents.”

“There are, then, still more of these greedy animals?” Jules inquired.

“Yes; they are somewhat like insects: after they are all gone there are

still some left. The world seems to be a pasture delivered over to the

mandibles of larvæ and the incisors of rodents.

“Dormice, of many varieties, live in the woods and orchards and eat

fruit. These rodents have the agility, elegance of form, and rich fur

of squirrels. They make their home in hollow tree trunks, holes in

walls, and crannies in rocks. During the winter, when fruit is lacking,

they remain in a deep sleep.

“The dormouse proper is found in Provence and Roussillon. It is a

pretty creature, reminding one of the squirrel. Its tail is long and

thickly covered with hair; its fur ashy brown on the back and whitish

under the belly. At night it ravages the fruit-trees, and no one knows

better how to pick out the pear, the peach, or the plum at just the

right stage of ripeness. You have, let us suppose, looked over your

fruit with satisfaction and decided to give it one more day of sunshine

to bring it to perfection. The next morning you go out to gather the

harvest and, lo and behold, it is gone; the dormouse has been there

before you.

“The garden dormouse is smaller, being about as large as the black rat.

Its coat is a pleasing mixture of red, white, and black, the back being

red, the belly, paws, cheeks, and shoulders white, and the parts about

the eyes and down the sides of the neck black. This animal is scattered

all over France. It lurks about dwellings, in gardens, and among vines

and shrubbery, living chiefly on fruit, which it ruins in great

quantities, tasting first one choice specimen and then another, without

finishing any of them. Garden dormice spend the winter several in one

hole, where they sleep all curled up amid the supplies of walnuts,

almonds, and hazelnuts that they have laid up.”

“Then if they sleep,” said Emile, “they don’t need any food.”

“Pardon me, my boy; they do need food, and badly, though not while

sleeping, but when they wake up. This awakening takes place at the

beginning of spring, when the sun is first warming up the earth. At

that time of year there is no fruit to be had; and the garden dormice,

after their fast of several months, have a tremendous appetite, as you

can easily imagine. What would become of them now, poor little things,

if it were not for their supply of nuts?”

“Those little dormice are very prudent,” Emile remarked. “They know

that at the end of their long winter’s sleep they won’t find any fruit

in the orchards, and so they lay up provisions beforehand. But why

don’t they put by apples and pears if they are so fond of them?”

“Because apples and pears would spoil, whereas almonds and hazelnuts

keep very well.”

“That’s so. I hadn’t thought of that, but the little dormouse had.”

“No, it does not think of it, either. It does not know that pears spoil

and nuts keep, because it has never tried to keep pears. It does not

foresee that when it wakes up, the fruit-trees will not be bearing

fruit, will hardly have their first leaves; it does not know how long

it would have to wait to find a pear to nibble; it knows nothing of all

these things, which it is now about to become aware of, perhaps for the

first time, through experience. Some one else thinks for the dormouse

and gives it the prudence to store up nuts in a hole in the wall; some

one who understands, foresees, and knows everything. And that some one

is God, the Father of the man who plants the pear-tree, and Father also

of the little dormouse that is so fond of pears.”
