 the snowy cow herons that were always with the buffaloes during the daytime. These would fly about above the reeds from one part of the herd to another, and at times, where the reeds were low, they could be seen riding along perched on the backs of the animals. Having thus located the herd and determined the general direction of its movements, we would go to a point at the edge of the marsh where it seemed likely that the animals would come out, or at least come near enough to be visible in the shorter reeds. It was in this way that we secured the specimen that makes the young bull of the group—and two weeks spent there resulted in securing no other specimen. On this one occasion the buffaloes, accompanied by the white herons, had come to within about a hundred yards of our position on the shores of the swamp. They were in reeds that practically concealed them, but the young buffalo in question, in the act of throwing up his head to dislodge a bird that had irritated him, disclosed a pair of horns that indicated a young bull of the type I wanted. A heron standing on his withers gave me his position, and aiming about two feet below the bird, I succeeded in killing the bull with a heart shot.
