As they turned to obey his instructions the great brute charged with a furious trumpet.

His first onslaught the boys avoided by slipping behind a tree, more from instinct than anything else. The impetus of the maddened animal's charge carried him by the tree and before he could stop himself and turn his ponderous body for a fresh attack he had gone some yards beyond the boys.

Bellowing with fury the huge creature made ready for a fresh charge, but by this time Billy and Lathrop had seized the creepers and were both several feet above the ground. In his haste, however, Billy's luckless rifle twisted between his legs and almost caused a disaster. For a second he hung helpless, trying to kick the weapon free. But it hung by its leather shoulder band and he was unable to do so instantly.

The boy, with a despairing cry, gazed at the onrushing elephant and could almost feel himself being seized by its mighty trunk and dashed to death, when a pair of strong, black arms seized him and dragged him up to a place of safety. The man who had taken this risk was their friend Umbashi, and as Billy thanked him he felt a feeling of real respect for this half naked savage who had risked his life to save another's.

After two or three more charges the animal seemed to get tired of this method of attack and stood beneath the tree shaking with rage, very much like a bull that has driven a boy to refuge in an apple-tree. It was evident that it was time to either kill the brute or drive him off unless the party desired to spend an unlimited time in the trees.

"The fire-weapon," shouted Billy's friend, "use the fire-weapon."

Billy raised the long Arab weapon and fired. The bullet struck the elephant on the right ear with no more effect than to further anger him.

"Aim between the eyes," cried the savage.

Billy felt for a fresh cartridge and made a discovery.

In scrambling up the tree he had ripped off the skin bag and his store of Arab cartridges, none too many, lay on the ground at the foot of the tree. When this intelligence was communicated to the tribesmen clinging in the other trees they held a shouted consultation the result of which was that, to the boys' amazement, one of them deliberately dropped to the ground and attracting the elephant's attention began to run him in circles. Now as the man could run fast and from time to time another took his place and the elephant had to use a lot of effort in turning corners, it soon became evident that the big pachyderm was tiring of the exercise.
