The flotilla had reached within about four miles of the shore, and of a tolerably extensive native settlement built thereon on both sides of a river which at that point emptied itself into the lake, when a sudden confused beating of drums and blowing of horns seemed to indicate that the menaced tribe had at last become awakened to the unpleasant fact that an invasion of their territory was imminent. The summons was responded to with very commendable celerity, the men swarming out of the settlement like ants out of an ant-heap; and in less than ten minutes nearly a hundred canoes were launched and manned, and advancing boldly to meet the enemy, whilst the laggards pushed off by twos and threes as soon afterwards as they could get down to the beach, all making the most strenuous efforts to join the main body.

To the observers on board the Flying Fish it seemed that the attacked party had made a grave mistake in thus taking to their canoes and advancing in them to meet the enemy; the colonel’s impression being that they would have done better if they had awaited their foes on the beach and harassed them during their attempt to effect a landing. But it soon became evident that the threatened tribe knew perfectly well what they were about, their canoes being larger and steadier than those of their opponents, and their method of handling them greatly superior.

The opposing forces encountered each other at a distance of about two miles from the western shore of the lake, when a simultaneous discharge of arrows was poured in by both sides, after which the two fleets closed, and a most determined and sanguinary battle commenced. The invaders outnumbered their opponents nearly in the proportion of two to one; yet the latter not only gallantly held their own, but actually appeared now and then to gain some slight temporary advantage. Spears were thrown and arrows were shot by hundreds; the heavily-knobbed war-clubs were wielded with untiring activity and terrible effect; and, occasionally, a flash and a faint puff of smoke followed by a report told that one of the ancient muskets had been brought into play. The shouting of commands, the cries of anguish or defiance, the shrieks of the wounded, and the yells of triumph united in the creation of a most deafening din; and that it was not noise only, but work as well, was speedily manifested by the numerous bodies, splashing and struggling in the agonies of death, or floating quiescent on the surface of the lake.

“How stubbornly the rascals fight!” remarked Lethbridge at last, when the battle had been hotly raging for fully three-quarters of an hour without yielding to either side any decided advantage. “I wonder what the quarrel is all about?”

“It is difficult to say,” answered the professor, who seemed to consider the question as addressed to himself; “it may be a simple case of tribal animosity; it may be an attack of retaliation; or it may be a slave-hunting expedition. It is pretty sure to be one or the other of those three, but it is impossible to say which.”

“Well,” remarked Mildmay, “whatever the cause of the fight, my sympathies are all with the weaker side. Cannot we help the poor wretches a little? A shot or two from our rifles—”

“Would ensure to either party a victory,” interrupted the baronet. “Yes; that is quite true. But how can we tell which party—if either—is fighting in the cause of right and justice? We cannot take the part of either the aggressors or the defenders without a certain lurking doubt that in so doing we may perhaps be unwittingly giving aid and encouragement to the evil-doer. My sympathies are, like yours, on the side of the defenders; but I am afraid we must let them fight it out unaided.”

And fight it out they did in the most gallant manner, the invaded baffling all attempts on the part of the invaders to get even a small portion of their force between them and the shore; and finally, by what looked like a last supreme and desperate effort, putting the foe to flight, and pursuing him triumphantly and persistently in his retreat, harassing his rear, cutting off and capturing stragglers, and in every possible way worrying and annoying him so thoroughly that, to those on board the Flying Fish, it looked unlikely in the extreme that the attack, whether provoked or not, would ever be repeated.

The combatants had evidently been far too busy to notice the extraordinary apparition floating in the sky above them; but just as the battle was about to commence a crowd of women and children, with a few decrepit old men, had assembled on the beach, seemingly to watch the conflict; and on bringing the telescopes to bear on these it soon became apparent, by their gestures and cries of amazement, that they had seen the ship.

“Yes,” said the professor, peering through his telescope, “they see us undoubtedly, but they can detect neither form nor details. The sun is immediately behind them, you will observe; consequently, as it is shining full upon our burnished hull, those people, in the position they now occupy, will be able to see nothing but a shapeless blaze of dazzling effulgence, which they will doubtless take as an outward manifestation of their particular deity’s favour, and an indication that he is present to crown their cause with victory.”
