“It might, of course,” admitted the skipper; “but, all the same, I do not believe it was. For the people who supplied Captain Harrison with false information would surely know enough of him and his methods to be certain that, failing to find anything in the nature of a slave factory at King Olomba’s town, we should not leave the river again until we had thoroughly explored it; and if they knew the river at all they would also know that the factory on the Camma Lagoon could scarcely be overlooked by us. No; in my own mind I feel convinced that the factory which we destroyed to-day was not the one in which those fellows are interested; there is another one somewhere in the river; and I will not leave until I have discovered and destroyed it. But that only brings me back to the point from which I started, and once more raises the question, Why did they cast us away within a few miles of this other factory which I am persuaded exists? Is it that the place is so strongly fortified that they are confident of our inability to take it? Or is there something else at the back of it all, of which we have not yet got an inkling?”

Purchase shook his head hopelessly. “Upon my word, sir,” he answered, “it is quite impossible for me to say. When you come to put the matter like that it becomes as inexplicable as a Chinese puzzle. What is your own opinion?”

“I haven’t been able to form one at all,” answered the skipper. “But the matter is puzzling enough to convince me that it would be folly on our part to assume that the casting away of the ship is the beginning and ending of the adventure; therefore we will neglect no precautions, Mr Purchase, lest we find ourselves landed in an even worse predicament than our present one. Our first and most important precaution must be to maintain a strict watch throughout the night. It need not be a very strong watch, but it must be a vigilant one; therefore each watch will be kept under the supervision of an officer who will be responsible for the vigilance of the men under him. Moreover, all hands must see that their muskets and pistols are loaded and ready for instant action; for it would not be a very difficult matter to surprise this camp of ours sometime during the small hours. Just come outside with me and let us take a look round.”

The result of the above conversation and the “look round” was an arrangement that the night was to be divided into five watches of two hours each, beginning at eight o’clock in the evening and ending at six o’clock in the morning; each watch to consist of twelve men, fully armed, who were to act as sentries, half of them being detailed to watch the river in the neighbourhood of the boats, while the other half kept watch and ward over the land approach to our encampment, being stretched across the narrow isthmus in open order from the water’s edge on the river-side to that on the sea-side. Each watch was commanded by an officer, with a midshipman under him; and the general orders were to fire a single shot at the first sign of anything of an alarming character, and then retire upon the camp, if an attack should threaten to cut off the outpost from the main body.

The first watch was taken by the captain, with me for his subordinate; and I was given the command of the party of six guarding the shore approach to the camp, while the skipper took the party mounting guard near the boats, as it was his opinion that if danger threatened it was most likely to come by way of the river.

My instructions were to march my men out to a distance of not more than two cables’ lengths from the camp, and there take such cover as might be possible. At first sight it did not appear that there was the least bit of cover of any description available, for the spit or peninsula on which we were encamped was just bare sand for a distance of fully a mile from the spot whereon our camp was pitched, and then there began a growth of scrubby bush which gradually became more dense as one proceeded in a southerly direction; but I solved the difficulty by causing each man to scoop a little pit for himself in the loose sand, in which it was easy for him to crouch perfectly concealed particularly as there was no moon, and the light from the stars was not strong enough to reveal objects at a distance much beyond a quarter of a mile.

The first, second, and third watches passed uneventfully; but the fourth watch was little more than half through when—about a quarter after three o’clock in the morning—the whole camp was roused from its slumbers by the sound of musket-shots, one from the party guarding the boats and the river approach, quickly followed by three in rapid succession from the contingent that occupied the sand pits stretched across the neck of the peninsula. Then three or four more shots from the river party spurted out, and it began to dawn upon us that the matter threatened to be serious. Of course none of us had thought of discarding any of our clothing that night, the second shot therefore had scarcely pealed out upon the night air before we in the camp were upon our feet, with our weapons in our hands, and all drawn up in regular array ready for the next move in the game, with the skipper in command.

“Where are Mr Fortescue and Mr Copplestone?” demanded the captain, looking about him, as soon as the first momentary bustle was over.

“Here I am, sir,” answered I, stepping forward and mechanically touching my hat; and “Here I am, sir,” answered Tom Copplestone, suddenly appearing from nowhere in particular.

“Mr Fortescue,” ordered the captain, “take to your heels and run out to Mr Nugent as fast as you can; ascertain from him the reason for the firing from his party; ask him whether he requires any assistance; and then return to me with his reply as quickly as possible. Mr Copplestone, you will run down to the boats with a similar message to Mr Marline.”
