Part 18

The California woodrat is not only a food hoarder but a notable thief and robber. A nest was found that was a veritable tool chest and pawn shop! It contained fourteen knives, three forks, six small spoons, one large soup spoon, twenty-seven large nails, hundreds of small tacks, two butcher knives, three pairs of eye-glasses, one purse, one string of beads, one rubber ball, two small cakes of soap, one string of red peppers, several boxes of matches, with numerous small buttons, needles, and pins. Apparently these woodrats are as ambitious for unnecessary and useless possessions as is man himself. Their big storeroom did, however, contain a larder in which they had some of their favourite food, such as seeds and nuts.

Some animals have learned not only to acquire, but also to defend and protect, all their property. We see in the human world how strong is the impulse to collect, and children will invariably collect anything from pebbles to peach-pits, if they see other children doing the same thing.

Most animals that do not hoard are those that forage for food, or fish, and rarely have permanent homes. The orang-outangs, for example, are regular gipsies, and go from place to place wherever food is plentiful. They take life easy, and sometimes during their journeys select a suitable spot near the seashore and have a real picnic. A scout has already discovered the right spot for getting big oysters, of which they are exceedingly fond, and when they have assembled, certain ones proceed to dig up the oysters, which they hand to others on the shore and they, in turn, place them on big stones, and proceed to open them for the feast. If one of the fishermen-monkeys discovers an oyster open, he will not insert his hand to remove the meat until first placing a stone between the valves. This assures him protection against the closing of the oyster. In most cases, they open the oysters by first placing them on stones and then using another stone as a hammer. These facts are vouched for by no less authorities than Gamelli Carreri, Dampier, and Wafer.

It is only a matter of time until many animals will understand the use of man-made tools. Some have already learned to use such tools as they make and shape for themselves. Monkeys and apes are already gifted in this art. Of course, under domestication, they use knives, forks, spoons, and dishes not so much from intelligence as from imitation. This, however, might be said of many human beings. I have seen an immense chimpanzee sit in a chair, set his own dinner table, use his knife and fork correctly when eating, and take great delight in the use of his napkin, which he always carefully refolded when his meal was over.

The human-like qualities of apes and monkeys, however, need scarcely be told. They are so very similar to man in most ways that there are few things they cannot do. Aelian tells of an ape which learned to drive horses skilfully. He knew just when and how to use the whip, how much slack to allow in the reins, and when to tighten them! They greatly resent any intrusion on their hunting-grounds, and make use of sticks and clubs to protect them. The chief is always armed with a club, and is thoroughly skilled in the use of it. It sometimes happens that an elephant will come to the same tree to seek food that apes frequent, and although they have no enmity towards each other, they like the same kind of food. As soon as the ape sees the elephant reaching his trunk among the branches, he immediately slips near the elephant, and when an opportunity presents itself, he whacks him over the trunk with his club! The infuriated elephant runs away in terror!

A story is told of a party of foraging apes who went into a cornfield with the purpose of robbing it, and discovered two men. They immediately rushed upon them and attempted to poke their eyes out with sticks and would have succeeded but for the intervention of two other men who chanced to be near. The extreme cleverness of apes in applying their reason and judgment is shown in Vosmaer's account of the female orang-outang, who tried to open the padlock of her chain with a small stick. She had seen her master open it with a key, and she exactly imitated the motion of his hands in the attempt.

Man shows a disposition to deny animals all traits and characteristics which are similar to his own. This reminds us of a remark that Cardinal Newman once made that men know less of animals than they do of angels. Why should we show such foolish pride and delusion, and try to baffle one of God's great facts? When men attempt to extinguish the idea of animal intelligence and sentiment by referring to it as instinct, we are reminded of the desert ostrich, which buries its head in the sand and thinks it cannot be seen. We should proudly acknowledge the wonderful human-like methods of these food conservers of the animal world, and recognise in all this a guiding Providence who provides for and protects all his creatures, be they great or small.

TOURISTS AND SIGHT-SEERS

"Every night we must look, lest the down slope Between us and the woods turn suddenly To a grey onrush full of small green candles, The charging pack with eyes flaming for flesh. And well for us then if there's no more mist Than the white panting of the wolfish hunger."

The desire to travel and see the great world is by no means peculiar to the human race. It is found among animals to such a degree that groups of them will often leave their homes in one country and journey to another. These strange wanderlust habits are noticed even by the casual observer, and no special insight is required to see that these wise creatures have their annual tours excellently arranged and marked out. Their route is possibly as definitely arranged before starting, as is the route of a human traveller. They have their selected eating places arranged, know every danger spot and the enemies they are likely to encounter.

The members of these co-operative tours take life tickets, and each tour lasts about one year. One of the most unusual instances of such co-operation is that of the lemmings of the Scandinavian countries. These are animals of the mouse tribe, which live in the mountainous districts. They live upon roots and grasses. They breed very rapidly. At certain times they go from the centre of Norway to the east and west, crossing valley, hill, and river in great masses. Many are destroyed by birds and beasts of prey, but finally the survivors reach the Atlantic on the Gulf of Bothnia and, for some strange unknown reason, plunge in and die. Only enough remain from one season to another to propagate the species. It is an immense co-operative suicide society.

Rivers and valleys are sometimes effectual barriers. On the plains of the Amazon great numbers of animals are found on one side of the river only; these have not been able to cross to the other. On the north side of the Rio Negro are two varieties of monkeys, the brachiurus conxion and the jacchus bicolor, which are unknown on the south side. Of course, water-loving animals, such as seals, whales, and porpoises are at home in the water and can swim for days without stopping. Quite a few animals can swim for a short distance, but comparatively few for long distances. In the early days in North America it was not uncommon for buffalo to swim across the Mississippi River. Rats and squirrels often migrate in great numbers. It oftentimes happens that Arctic animals travel from one place to another on floating ice. In the South American waters it is a common sight to see floating islands covered with plants and trees upon which there are live animals; and while these animals are likely to perish, they are oftentimes carried safely to land. Eagles have often been instrumental in bringing new species of animals to islands where they had previously been unknown, their purpose being to provide food for their own young. Some of these animals would escape and henceforth become citizens of their new habitation.

An interesting division of migrants is that of the casual travellers, like the men and women who always remain at home except when special business calls them away. Sudden climatic changes, or the scarcity of food, often cause stay-at-home animals to make tours into new territories. As a good instance, I might cite the case of three wolves, which I saw entering Jackson Park in Chicago, during very severe weather when Lake Michigan was frozen over. The morning papers stated that because of forest fires in Michigan, and the extreme cold, which not only made food scarce for the wild animals of Michigan, but froze the Lake, many of them had come across the ice into the great Chicago parks seeking food and shelter.

The subject of animal travel is full of interesting and difficult problems, and not the least interesting nor the least difficult is the question of just how they find their way to and from various places. Many naturalists tell us that these animals are led by inherited instinct along the migration lines followed by their forefathers. But even if this were true, what made them originally follow such a course?

Wild horses when travelling always have a leader as well as several sentinels for each herd. By some unknown code this leader makes known his wishes and directs the movements of the herd. No human army could have greater order or more perfect obedience to commands; and under him there is absolute unity by means of which the carnivorous animals, such as the wolf, the jaguar, and the puma, are repelled. Wild deer invariably have a leader, and while we do not know how he obtains his position, nor how he directs his followers, we do know he is highly successful in his efforts.

No act in the animal world bespeaks more intelligence than that of placing sentinels, especially during a journey. Horses show striking skill and ingenuity in the choosing and placing of their sentinels. Any one who has been fortunate enough to have seen them travelling in the forests of South America, where the wild horses are gregarious, and travel in herds of five hundred to a thousand, has noticed that sentinels are always stationed around the herd. These animals are not well prepared for fighting, and experience has taught them that their greatest safety is in flight, and so, when they graze or sleep, sentinels are always on the look-out for enemies. If a man approaches, the sentinel at first walks toward him, as if to make sure what the enemy is, and what he desires, if the man goes nearer to the herd, the sentinel neighs in a most peculiar tone. Immediately the herd is aroused, and gallops away, not in confusion, but perfect order, as though its members were human soldiers.

The same is true of the white-legged peccaries, so plentiful in Guiana. They congregate by the thousands, choose a leader whose position is always at the front, and travel for hundreds of miles through the great forests. If they come to a river, the leader halts, as if to make sure that all is well for crossing, then he plunges into the water and is followed by his immense army. The sureness of the leader would suggest that he has been over the same route many times before--perhaps this is why he has been chosen! If an enemy appears, or any form of danger is approached, they carry on an immense amount of chattering and proceed only when they have talked it out. Any hunter that should be foolish enough to attack them, unless he were already up a tree, would be torn to pieces with their terrible teeth and tusks. They are as bloodthirsty as the wild boars of the Black Forest of Germany, and will sometimes actually tear down a tree up which an enemy has escaped, that they may kill him.

The African apes have an interesting way of sending their sentinel to the top of an adjacent rock or tree, that he may look over the surrounding valleys and plantations before they go to plunder a garden or field. If he sees any danger, he utters a loud shriek, and the entire troop immediately runs away. The monkeys of Brazil post a guard while they sleep; the same is true of the chamois and other species of wild antelope.

A few years ago, many of the sheep in the northern part of Wales had become quite wild, and they usually grazed in parties of twelve to twenty, always having a sentinel so stationed as to command a prominent view of the surrounding territory. If any animal or person came near, he would give a peculiar hiss or whistle, repeating it two or three times, at which the whole herd would scamper away to places of safety.

One of the most striking facts about migration is its never-failing regularity and success. Most animals migrate at the recurrence of the breeding season. Of these, the great sea-turtle, which seeks the shallow water and deep sandy hills when ready to lay her eggs, is well known. Notwithstanding the great risks that practically all travelling animals assume, they are successful as a whole in their travels, and many return to bear testimony to a successful trip even across continents and sometimes the ocean. They migrate, for a variety of reasons. When it is not for a more desirable climate, nor more food, nor even better breeding grounds, we must either believe it is because of the natural desire to travel, or frankly admit that we do not understand it.

The Icelandic mice have probably the most curious methods of travelling of all migratory animals. Dr. Henderson, an authority on Iceland, not only verifies the fact himself, but gives the names of many prominent investigators who have seen the mice crossing small rivers and streams on thin pieces of dry board, dragging them to the water, launching them, and then going aboard their little rafts. They then turn their heads to the centre, and their tails, which hang in the water, are used as paddles and rudders until they reach the destined shore.

Among travellers none are more famed than the camels. In their sphere and use they are supreme, and Nature has prepared them especially for travelling on the dry, hot, and barren deserts. They are truly the "ships of the desert" for they travel on a sea of sand, and their pad-like feet, so poorly adapted for travel on moist soil, is admirably suited to the desert sands. They are capable of travelling many days without food or water, and are used extensively in the desert regions of the East not only as beasts of burden but for their milk, which is an important article of diet in those countries where the camel is at home.

Animals that do not migrate, especially those living in cold climates, change their clothing at regular intervals. Their hair or fur increases in thickness in winter. If we compare the Indian and African elephants of to-day, whose delicate thin hair is scarcely noticeable, with the great extinct mammoth, which had an enormous amount of woolly fur, we readily see the great difference in their clothing. Yet these animals are members of the same great family. The same difference may be noted with horses: the Arabian horse, for example, has short, glistening fur, while those of Iceland and Norway have very thick fur; the same is true of Northern and Southern sheep. Animals which live in temperate regions, put on much thicker coats in winter, and shed them as summer approaches.

The love of their original homes is one of the most striking features of certain animal travellers. The fierce struggle for existence and the territory required for an animal's home largely determine the amount of effort they make to seize and hold certain possessions. A pair of wildcats, for example, require a comparatively small hunting ground. But this they will defend against invasion even to the point of death. There are many more evidences showing the animals' love of home, and that they also know the meaning of home-sickness.

Not a few animals have learned definitely to lay out and obtain recognition for the boundaries of their respective ranging-grounds. This is amply proven by their respect and recognition of rights of way. Animals of certain farms seem to know the exact boundaries of their grazing lands and pastures, and to teach this knowledge to their young. In addition they often police their lands and pastures against intruders. Woe unto any traveller found on the wrong highway! It is not uncommon for the transgressor to be pushed from a right of way to the rocks below. More than once a court's decision regarding disputable territory has been based on the sheep's recognition of boundary; those sheep slain in battle or otherwise injured while trying to invade the questionable territory have been paid for by the owner of the transgressing sheep.
