Waiting till all were prepared, the four defenders rapidly emptied their magazines into the enemy, until the barrels of their weapons were so hot that they blistered their fingers. Then snatching up the piles of ammunition which they had placed close at hand, they scrambled from the trench, and, running swiftly across the entrance-hall, dived into the central tunnel, for all the world like rabbits taking to their burrows.
"Halt!" cried Jim sharply, at this moment. "Without a torch we shall be lost. Wait here till I get one."
Returning, he ran to the fire, and quickly secured four flaming brands, then he rejoined his comrades, noticing as he was about to enter the workings that the cries of the attackers had suddenly ceased, and that they had all come to a halt outside the mine, as if too fearful to enter it. But scarcely had the fugitives traversed more than a hundred yards of the tunnel, when loud shouts and cries again rent the air, and being magnified by the enclosing walls, came echoing and reverberating into the working. Indeed, the natives had at last overcome their superstitious terrors, and, rendered desperate by the baffling tactics of the infidels, had flowed into the entrance-hall till it was packed with humanity. Then a second pause ensued, for the passages which led on into the hill looked dark and forbidding. However, a leader was forthcoming, who, imitating Jim's example, snatched at one of the fiery brands, and, having peered into each one of the tunnels in succession, finally waved to his comrades to divide and search all of them.
Meanwhile the fugitives had sped on without a pause, and very soon arrived at the large chamber, which seemed to be the heart of the workings. And here they halted to listen for sounds of the pursuers.
"It is perfectly clear," said the colonel, seating himself to regain his breath, "that these fellows have overcome their fears, and are in hot chase. It occurs to me at the same time that the movement we have made was a most excellent one, for the very fact that there are so many channels leading into the hill will cause the Somalis to divide up into parties. Then in the darkness they will lose one another, and in that way will fall easy victims to our rifles, if they happen to come up with us. My advice is that we sit here for a little while, and then take matters more easily, for we shall require all our powers later. Perhaps we shall find an exit, and in that case we shall be obliged to travel fast to the zareba."
Accordingly the party crossed to the other side of the chamber, and entered the tunnel which stood opposite to that from which they had just emerged. Then lowering their torches, so that the flames could not be easily observed, they sat down to await events. Presently they became aware that some, at least, of the natives were close at hand, and prepared to push on, or repel the pursuers, as circumstances should dictate. But there was no need for interference on their part, for as they peered into the depths of the chamber, the glowing end of a firebrand suddenly appeared, the feeble light enabling them to perceive that five men only accompanied the bearer. They were on the point of levelling their rifles at these intruders when there was a shout from one of the side tunnels, and before the onlookers could realize what was about to happen, a second party of Somalis rushed into the open space, and mistaking the first for the flying infidels, threw themselves with spear and sword upon them.
"I almost expected a catastrophe of that sort," whispered the colonel; "and it is very probable that it may occur elsewhere, for our pursuers are too angry to be cautious. I think we may safely leave them to themselves and push on now deeper into the mine."
Acting upon this advice, the party stole silently away into the darkness, leaving the Somali warriors struggling desperately with one another. A trudge of nearly half a mile brought them to a point which seemed to be the farthest limit of the mine, for here galleries ran in every direction, and a glance at the rough surfaces of the walls showed that the workings had been deserted in a hurry, and not because gold was no longer to be found. Indeed, had it been possible, the three Englishmen would have gladly stayed to investigate the matter, for there were numerous interesting relics scattered about. But to delay then might have brought disaster to the party, and, therefore, they at once began to search for an exit.
"I feel sure we are not far from the open air," cried Jim, suddenly coming to a stop in the centre of a wide space, from which the tiny galleries cut into the hill. "Come here, and you will feel quite a draught blowing upon your heads, and——By Jove! Look at my torch!"
He held the brand above his head, and as he did so the dull red end began to glow brightly, and then, fanned by an invisible stream of air which played upon it, it burst into a brilliant flame, which effectually lit up the surroundings.
