Animals sometimes start fighting among themselves, and to separate them is exceedingly dangerous. Perhaps the queerest encounter ever witnessed at this remarkable animal exchange was that which took place between a hippopotamus and a kangaroo. "The latter," said Mr. Hagenbeck, "was the largest kangaroo I ever had in my possession; it was over six feet high, and a very powerful animal. It occupied a stable close to that of the hippo, and one night the kangaroo jumped over its fence into the hippo's pen. The kangaroo landed in the hippo's tank, which was empty. "It was two o'clock in the morning when the incident occurred, and when I arrived on the scene I could not help smiling, the whole affair being so comical. There stood the monster hippo with his enormous mouth open, snapping at the kangaroo down in the tank below. The moment the hippo moved down towards the tank the kangaroo sprang into the air and smacked his opponent in the face with his great forefeet. When the hippo got too venturesome, by endeavouring to walk into the tank despite the blows, the kangaroo took a mighty leap upwards and struck his enemy with his hind feet, inflicting terrible scratches with his claws. "Try as he would the hippo could not get into that tank to attack the kangaroo. To separate the combatants was a puzzle. We did it ultimately by fixing up an arrangement by which we dropped a large seal net over the kangaroo, and then, drawing in the cords, secured him. To divert the hippo's attention, the moment the net was lowered over the kangaroo one of my men pretended to enter the cage. The ruse succeeded, and the kangaroo was safely released and taken back to his proper quarters. "I could tell you many more adventures," said Mr. Hagenbeck, as we shook hands on parting, "but the fact is I have just written a book in which I have given a complete story of my life, and I have embodied in it the little adventures I have had while hunting, collecting, and handling my strange merchandise." That book certainly ought to make good reading. [Illustration] HOW WE CAPTURED THE REBEL CHIEF. BY E. F. MARTIN, LATE OF THE ROYAL NIGER COMPANY'S SERVICE.
