Recreation is as common among animals as it is among children (in Colours)Frontispiece

The Indians claim that the mother bison forced her calf to roll often in a puddle of red clay, so that it might be indistinguishable against its clay background6

The zebra is one of the cleverest of camouflagers. The black-and-white stripes of his body give the effect of sunlight passing through bushes7

Monkeys are the most musical of all animals. When they congregate for "concerts," as some of the tribes do, the air is filled with weird strains of monkey-music20

Cats, unlike dogs, are very fond of music. And it has been proved that their music-sense can be developed to a remarkable degree21

A happy family of polar bears. The young cubs wrestle and tumble, as playfully as two puppies. This play has much to do with their physical and mental development34

Dryptosaurus. The prehistoric animals, too, undoubtedly had their play time, with games and "setting up" exercises35

The mother opossum is never happier than when she has her little ones playing hide-and-seek over her back38

This young fox came from his home in the woods daily to play with a young fox-terrier. He is now resting after a romp39

Naosaurus and Dimetrodon, two extinct armour-bearers who should have been well able to protect themselves50

An armour-bearer of prehistoric times whose shield was an effective protection against enemy horns51

To the polar bear the ice and snow of the Far North means warmth and protection. The mother bear digs herself into a snowbank, where lives quite comfortably throughout the winter84

The sharp claws of the ground squirrel are efficacious tools in digging his cosy underground burrow85

The coyote can readily distinguish whether a herd of sheep is guarded by one or more dogs, and will plan his attack accordingly94

The zebu, the sacred bull of India, in spite of its domestication, has an agile body and a quick, alert mind95

Roosevelt's Colobus. These horse-tailed monkeys chatter together in a language exclusively their own, yet they seem to have no difficulty in making themselves understood by other monkey-tribes112

A tamed deer of Texas, whose constant companion and playmate was a rabbit dog. Between the two, there developed, necessarily, a common language113

Water-loving animals, like the beavers, seemingly take great pride in their toilets. Their fur is always sleek and clean122

Great forest pigs of Central Africa. Like the common domesticated hogs, they will seek a clay bath to heal their wounds123

The Rocky Mountain goat has many means of defence, not the least of which is his agility in climbing to inaccessible places134

Wild boars are among the most ferocious of animals. By means of their great strength alone they are well able to defend themselves135

Brontosaurus. The animals that seemed best equipped to defend themselves are the ones that, thousands of years ago, became extinct144

This prehistoric monster was equipped not only with a pair of strong horns but with a shield back of them as well145

The beaver is the greatest of all animal architects. His skill is equalled only by his patience (in Colours)158

The skunk mother tries to keep on hand a good supply of such delicacies as frogs and toads, so that her young may never go hungry172

The porcupine and the hedgehog have a unique method of collecting food for their young. After shaking down berries or grapes, they roll in them, then hurry home with the food attached to their quills173

The black bear is not one of the great migrating animals. The thickness of his coat must therefore change with the seasons188

Rabbits seem to have a well-devised system in their road-building, running their paths in and out of underbrush in a truly ingenious manner189

The mongoose, a scavenger of the worst type, feeding on rats and mice and snakes, and even poultry202

Diplodocus. The prehistoric animals, also, undoubtedly had their scavengers and criminals203

The Esquimo-dog is man's greatest friend in the Far North218

Chipmunks are among the most easily tamed of man's wild friends, and they even seem fond of human companionship219

Men cruelly take the lives of these denizens of the wildwood, rejoicing in their slaughter, but the animal soul they cannot kill244

Two pals. There is between man and dog a kinship of spirit that cannot be denied245
