An instant later the nose of the steam launch shot into view, some fifty yards from the bank, and Dick caught a glimpse between the leaves of the big tree which sheltered him of the anxious face of Johnnie, peering from over the engine-well, and of the portly figure of the Dutchman, a portion of which was hidden by the cabin aft. He stood there prominent in the rays of the moon, a rifle in his hands, and his short sword attached to his side. Then, as his eye lit again on the group of natives, he lifted the weapon, and hardly had the report of Dick’s revolver died down when there was a flash, and the half-caste who had formerly robbed our hero, and who had now made such an artful attack upon the boats of the expedition, clapped his hand to his thigh and gave vent to a loud bellow. Then he turned and fired a shot at the Dutchman, a shot which flew past in the air, screaming and hissing towards the opposite bank of the river. But long before it could have reached that destination the robber had swung round on his heel, and with a shout of defiance had raced for the shadows. After him Dick sent the remainder of his magazine, while Meinheer Van Somering, when he had recovered from the consternation into which the shriek of the shot had thrown him, followed his example, much to our hero’s trepidation, for the bullets flew on either hand, cutting a shower of leaves from the trees.

“Steady, Meinheer!” he shouted. “You will be hitting us soon. We are here under the tree. I had to seek shelter from the light, for they would have picked us off easily. Bring the launch in and I will wade out to you. I fear that Mr Pepson is seriously hurt.”

Leaping overboard he pushed the boat clear of the tree and of the shadow, and soon had it alongside the launch, for the latter steamed gently into the shallows. Then the leader of the expedition was lifted aboard, the two boats were made fast to the stern of the steamer, and they pushed out into the stream.

“Better make for the far shore,” said Dick. “Then we shall not be treated to long shots.”

“Bud zese wicked robbers, Meinheer,” gasped the Dutchman. “Shall we led zem go free? Shall zey escape?”

“We can do nothing more,” was Dick’s answer, given with decision. “They are gone long ago. The forest has swallowed those who are alive. Let them run, Meinheer, and do not trouble any more about them at the present time. To-morrow, when there is light, we will visit the bank again and see what has happened to them. For the moment let us look to Mr Pepson. Now, Johnnie, steer us for the far side, and when you reach the shadow, come to a stop just inside its edge. Whatever you do, keep steam up, and have the propeller just moving, so that we shall not be drifted down-stream. Now we will light the lamp and see to our friend.”

Without hesitation he took the lead, now that Mr Pepson was incapacitated, for he realised in a moment that Meinheer Van Somering was not to be relied on in such an emergency. Indeed, he had been struck with amazement at the boldness already displayed by his stout friend, for who would have expected, knowing him as they did, that he would have dared to stand there so conspicuously on the deck of the launch and fire upon the robbers? Meinheer Van Somering had gone up in Dick’s estimation. He had proved that he had some store of courage after all. But he lacked self-control. At this moment when he should have been cool and thoughtful, for the danger had passed, he was tramping the deck from end to end, causing the stout launch to heel to either side. And every minute he would halt and stare at the forest which had just been left. At such moments his fist would close round his rifle, while his finger would feel for the trigger.

“Mein word!” he cried. “Bud zey would have killed us! Zey were robbers and murderers. Ah! I shod two of zem. Meinheer Dick, you saw me do id.”

“I saw,” growled our hero, “but we can talk of that later. Come and help with the lamp. Put your rifle down and leave the robbers to take care of themselves. Come, Meinheer, our comrade may be bleeding to death.”

There was a tone of command now in his voice, and at the sound Meinheer dropped his weapon and came aft. Already Dick had been able to find the lamp, and just as the Dutchman reached him he struck a match and lit the wick of the candle.
