For ere he could finish his sentence a rifle cracked somewhere near the top of the kopje, followed by another and another; the bugles rang out, and from the continued firing it seemed evident that the Boers were going against their ordinary custom and making a night attack.

If they did, though, they were to find the camp ready for them, every man and officer springing to his place and waiting for orders—those given to Captain Roby being, as his men were so familiar with the spot, to take half a company and reinforce the detachment on the kopje.

They found that the firing had completely ceased by the time they were half-way up, and upon joining the officer in command there, to Captain Roby’s great satisfaction, he found a similar scene being enacted to that which had taken place before him.

“Another false alarm, Roby,” the officer said angrily. “Your fellows started the cock-and-bull nonsense, and it has become catching. The sentry here declares he saw a couple of figures coming down in the darkness, and he fired. The idiot! There is nothing, of course, and the colonel shall make an example of him.”

Lennox was standing close up to the offender, and in spite of the darkness could make out that the man was shivering.

“Come, come,” said the young officer in a half-whisper; “don’t go on like that. You fancy you saw something?”

“I’m sure I did, sir,” replied the sentry, grateful for a kind word after the severe bullying he had received for doing what he believed to be his duty. “I saw two of them, as plain as I can see you now. I was regularly took aback, sir, for I hadn’t heard a sound; but as soon as I fired I could hear them rush off.”

“You feel certain?”

“Yes, sir; and the captain says it was all fancy. If it was, sir, I know—”

“Know what?” said Lennox, impressed by the man’s manner. “Speak out.”
