“The most valuable member of the family, so far as man is concerned, is the Fur Seal, also called Sea Bear. It is very nearly the size and form of the California Sea Lion, but under the coarse outer hair, which is gray in color, is a wonderful soft, fine, brown fur and for this the Fur Seal has been hunted so persistently that there was real danger that soon the very last one would be killed. Now wise and needed laws protect the Fur Seals on their breeding grounds, which are certain islands in the Far North. The young of all members of this family are born on shore, but soon take to the water. The Fur Seal migrates just as the birds do, but always returns to the place of its birth. Man and the Polar Bear are its enemies on land and ice, and the Killer Whale in the water. Mr. Fur Seal always has many wives and this is true of the other members of the Sea Lion family and of the Walrus. The males are three or four times the size of the females. Among themselves the males are fierce fighters.

“The true Seals are short-necked, thick-bodied, and have rather round heads with no visible ears. The Walrus and Sea Lions can turn their hind flippers forward to use as feet on land, but this the true Seals cannot do. Therefore they are more clumsy out of water. Their front flippers are covered with hair.

“The one best known is the Harbor or Leopard Seal. It is found along both coasts, often swimming far up big rivers. It is one of the smallest members of the family. Sometimes it is yellowish-gray spotted with black and sometimes dark brown with light spots.

“The Ringed Seal is about the same size or a little smaller than the Harbor Seal and is found as far north as it can find breathing holes in the ice. You know all these animals breathe air just as land animals do. This Seal looks much like the Harbor Seal, but is a little more slender.

“Another member of the family is the Harp, Saddle-back or Greenland Seal. He is larger than the other two and has a black head and gray body with a large black ring on the back. The female is not so handsome, being merely spotted.

“The handsomest Seal is the Ribbon Seal. He is about the size of his cousin the Harbor Seal. He is also called the Harlequin Seal. Sometimes his coat is blackish-brown and sometimes yellowish-gray, but always he has a band of yellowish-white, like a broad ribbon, from his throat around over the top of his head, and another band which starts on his chest and goes over his shoulder, curves down and finally goes around his body not far above the hind flippers. Only the male is so marked. This Seal is rather rare. Like most of the others it lives in the cold waters of the Far North.

“The largest of the Seals is the Elephant Seal, once numerous, but killed by man until now there are few members of this branch of the family. He is a tremendous fellow and has a movable nose which hangs several inches below his mouth.

“The queerest-looking member of the family is the Hooded Seal. Mr. Seal of this branch of the family is rather large, and on top of his nose he carries a large bag of skin which he can fill with air until he looks as if he were wearing a queer hood or bonnet.

“The Seals complete the list of animals which live mostly in the water but come out on land or ice at times. Now I will tell you of a true mammal, warm-blooded, just as you are, and air-breathing, but which never comes on land. This is the Manatee or Sea Cow. It lives in the warm waters of the Sunny South, coming up from the sea in the big rivers. It is a very large animal, sometimes growing as big as a medium-sized Walrus. The head is round, somewhat like that of a Seal. The lips are thick and big, the upper one split in the middle. The eyes are small. It has but two flippers, and these are set in at the shoulders. Instead of hind flippers, such as the Seals and Sea Lions have, the Manatee has a broad, flattened and rounded tail which is used as a propeller, just as fish use their tails. The neck is short and large. In the water the Manatee looks black. The skin is almost hairless.

“This curious animal lives on water plants. Sometimes it will come close to a river bank and with head and shoulders out of water feed on the grasses which hang down from the bank. The babies are, of course, born in the water, as the Manatee never comes on shore. Now I think this will end to-day's lesson and the school.”
