"Thanks, old fellow," said Lennox. "That has halved the risk. Perhaps the other fellow will think it too dangerous to stay." "Doesn't seem like it," said Dickenson, drawing in his breath sharply and clapping his left hand to his ear. "Don't say you're hit, Bob!" cried Lennox in an agonised tone. "All right; I won't if you don't want me to." "But are you?" "I suppose so. There's a bit taken out of my left ear, and I can feel something trickling down inside my collar." "Oh Bob, old fellow!" cried Lennox. "Lie still, man! What are you going to do?" "Bind up the place." "You won't if you stir." There was pretty good proof of this, for another shot whizzed between them. But he who sent it had been too venturesome in taking aim to revenge his comrade's fall, and the result of Dickenson's return shot was fatal, for he too sprang up into a kneeling posture, and they saw him for a few moments trying to rise to his feet, but only to fall over to the left, right in view of the two officers. Drew uttered a sigh of relief. "If we are to escape," he said, "we must stop any one from getting into that position again." "Look sharp, then," said Dickenson, whose keen eyes detected a movement on the other side of the river. "There's a chap creeping among the bushes on all fours." "I see him," cried Drew; and as he followed the enemy's movements and took aim, Dickenson, who was in the better position for commanding them, followed his example. "Missed!" cried Drew angrily as he fired and the Boer raised a hand and waved it derisively. "Hit!" exclaimed Dickenson the next instant. For he too had fired, and with better aim, the Boer drawing himself together, springing up, and turning to run, but only to stagger the next minute and fall heavily among the bushes, which hid him from sight. "Now for the next," continued Dickenson, coolly reloading. "Look out; I'm going to watch the other end." He turned sharply as a fresh shower of bullets came scattering around them, and looked keenly at the granite rock and its burden, half-expecting to see a fresh occupant taking aim. But apparently no one seemed disposed to expose himself anew to the rifles of such deadly shots, and the terrible peril to which the two fishermen had been exposed ceased for the time being, though the pair waited in momentary expectation of its recurrence. But the enemy did not slacken their efforts to finish their task by easier means, and the firing from the front went on more briskly than ever, the young officers contenting themselves with holding theirs and displaying no excitement now, their shelter, so long as they lay close, being sufficient, the worst befalling them now being a sharp rap from a scrap of stone struck from the rocks, or the fall of a half-flattened bullet. "That's right; don't fire until we are in an emergency," said Drew at the end of a few minutes. "In a what?" cried Dickenson. "In regular peril."
