Great, lumbering creatures were moving about along the edge of the river. They had heavy, swinging snouts, and from their enormous heads rose in great curves immense, yellowish things that looked like queer horns. Bolo had never seen any animals like these before. He watched them with fascinated eyes, wondering what they could be. Sometimes one of them would reach up into a tree with its great snout and pull a branch down. Two of them appeared to be quarreling, and one thrust its shaggy head and wicked looking tusks against the side of the other and made him stagger. Another waded out into the river and appeared to be drinking. In a minute he threw his trunk over his back and out spouted a stream of muddy water. There were fully twice as many of these animals as there were fingers on both of his hands.
