For more than an hour they waited in vain; for beyond an occasional stirring of the water, which caused it to overflow momentarily and trickle down the slope of the approach, nothing happened. Then a troop of small monkeys suddenly approached the cavern, and, seeing its human occupants, bolted, loudly chattering their indignation and fright. Shortly afterward a deer came tripping daintily across the glade, halted suddenly, threw up its head, and after sniffing the air for a few seconds, wheeled smartly round and bounded back into the forest. Another hour passed, and they were discussing in low tones the advisability of adopting some other plan for the enticement of the great beast from his lair, when they heard a sudden rippling and splashing of water in the interior of the cave, followed by a low moan and a gust of the offensive effluvium which Phil had noticed on the previous day, then a still more violent splashing of water, accompanied by a quick rush of overflow, a sound of ponderous movements, and then, looming out of the darkness, there vaguely appeared an enormous shape coming slowly and cautiously toward the carcass of the deer. In another moment it had advanced sufficiently to enable the watchers to observe the shape of its monstrous head, and Phil saw that in some way the creature had managed to free itself of the arrow which he had implanted in its left eye on the preceding day; but the brute had doubtless lost the use of that eye, for it could now be seen that it was closed, and that a small trickle of blood was flowing from between the lids. As it slowly advanced, the beast moaned frequently, while the disgusting odour which it exhaled momentarily became stronger. It had been agreed that if the beast could be enticed out of the water, all three of the hunters should, at a given signal, discharge an arrow at its right eye, and the trio were now standing, with bows fully bent, awaiting the signal. Another moment, and the brute slightly raised its head and halted, as though suspicious of danger. The slight raising of the head was just what was required to enable a perfect aim to be taken, and Phil at once gave the word "Shoot!"
