"He is more valuable than the crocodile," continued the Doctor, "and likewise he is more dangerous to pursue. The crocodile is harmless, unless you come within reach of his tail or jaws, and when attacked, his whole effort is to get away. The hippopotamus will show fight when attacked, particularly if it happens to be a mother with young."

"I'll tell you about a fight with one," said Abdul, "as soon as the Doctor has finished with his description of the animal."

"The flesh of the sea-cow resembles pork," Doctor Bronson continued. "The skin is tough and thick, and is made into those terrible whips which are called courbashes by the Arabs, and are used all over Africa. It can also be used for the soles of sandals and boots, and for helmets, shields, and other defensive things. It is not easy to send a bullet through it, and an old hippopotamus is nearly as impenetrable as the side of a locomotive engine. The teeth are valuable, as they are an excellent ivory, and for some purposes surpass the tusk of the elephant. So much for the value of the hippopotamus; and now for the story of Abdul's fight with one."

AN AFRICAN RIVER SCENE.

"Twenty years ago," said the dragoman, "there were more of these animals here than now, and there were also more crocodiles. In the neighborhood of Khartoum the river was full of them, and if you went out just at daybreak, in certain localities, you might see dozens of them in a single morning. The crocodile and the hippopotamus do not get along well together, and sometimes they have savage fights; but more frequently they mind their own business, and you may see them swimming peaceably side by side. Where both are so well able to take care of themselves they are not very likely to quarrel.

"The river full of these animals and the air full of birds made a very lively picture. Anybody who was fond of hunting could get all the sport he wanted.

"One morning I went out with an English gentleman whom I had accompanied from Cairo. He was an excellent shot, and on his way up the river had killed no less than seven crocodiles, which he secured, in addition to at least a dozen that had escaped into the water after being mortally wounded. He was anxious to kill a hippopotamus, and I promised to give him the opportunity.

"We went quietly along till we reached one of their haunts, where we brought the boat to land. Creeping through the reeds, I caught sight of a large sea-cow eating her breakfast and quite unconscious of danger. I beckoned to the gentleman, who came forward cautiously to get a good position for firing.
