through an open door, from which came a stream of light.

Motioning the others to stand still, he crept forward noiselessly till he could look into the room. A man was occupied in packing some articles of massive plate, clocks, and other valuables into a sack. He was alone.

Bob made his way back to the others.

"There's only one fellow there," he said. "If there are any more, they are upstairs. Let us have this one first--his back is to the door.

"Now, Wharton, you hold our handkerchiefs and the string. If he don't look round, I will jump on his back and have him down.

"The moment he is down, you two throw yourselves on him, and you shove the handkerchiefs into his mouth, Wharton. In the surprise, he won't know that we are only boys; and we will tie his hands before he has time to resist.

"Now, come on."

They were all plucky boys--for Wharton, although less morally courageous than the others, was no coward, physically. Their stockinged feet made no sound, and the man heard nothing until Bob sprang on to his back, the force sending him down on to his face. Bob's arm was tightly round his throat; and the other two threw themselves upon him, each seizing an arm, while Wharton crammed two handkerchiefs into his mouth. The man's hands were dragged behind his back, as he lay on his face, and his wrists tied firmly together. He was rendered utterly helpless before he had recovered from the first shock of surprise.

"Tie his ankles together with the other two handkerchiefs," Bob said, still lying across him.

"That is right. You are sure they are tight? There, he will do, now. I must lock him in."

This was done.

"Now, then, let's go upstairs.

"Now, fasten this last piece of string across between the banisters, six or eight steps up.

"Make haste," he added, as a faint cry was heard, above.

It did not take a second to fasten the string at each end; and then, grasping their sticks, the boys sprang upstairs. On gaining the landing, they heard voices proceeding from a room along a corridor and, as they crept up to it, they heard a man's voice say, angrily:

"Now we ain't going to waste any more time. If you don't tell us where your money is, we will knock you and the girl on the head.

"No, you can't talk, but you can point out where it is. We know that you have got it.

"Very well, Bill, hit that young woman over the head with the butt of your pistol. Don't be afraid of hurting her.

"Ah! I thought you would change your mind. So it is under the bed.

"Look under, Dick. What is there?"

"A square box," another voice said.

"Well, haul it out."

"Come on," Bob Repton whispered to the others; "the moment we are in, shout."

He stood for a moment in the doorway. A man was standing, with his back to him, holding a pistol in his hand. Another, similarly armed, stood by the side of a young woman who, in a loose dressing gown, sat shrinking in an armchair, into which she had evidently been thrust. A third was in the act of crawling under the bed. An elderly man, in his nightshirt, was standing up. A gag had been thrust into his mouth; and he was tightly bound, by a cord round his waist, to one of the bedposts.

Bob sprang forward, whirling his hockey stick round his head, and giving a loud shout of "Down with the villains!" the others joining, at the top of their voices.

Before the man had time to turn round, Bob's stick fell, with all the boy's strength, upon his ankle; and he went down as if he had been shot, his pistol exploding as he fell. Bob raised his stick again and brought it down, with a swinging blow, on the robber's head.

The others had made a rush, together, towards the man standing by the lady. Taken utterly by surprise, he discharged his pistol at random, and then sprang towards the door. Two blows fell on him, and Sankey and Fullarton tried to grapple with him; but he burst through them, and rushed out.

Bob and Wharton sprang on the kneeling man, before he could gain his feet; and rolled him over, throwing themselves upon him. He was struggling furiously, and would soon have shaken them off, when the other boys sprang to their assistance.

"You help them, Jim. I will get this cord off!" Fullarton said and, running to the bed, began to unknot the cord that bound the admiral.

The ruffian on the ground was a very powerful man, and the three boys had the greatest difficulty in holding him down; till Fullarton slipped a noose round one of his ankles and then, jumping on the bed, hauled upon it with all his strength--the admiral giving his assistance.

"Get off him, he is safe!" he shouted; but the others had the greatest difficulty in shaking themselves free from the man--who had, fortunately, laid his pistol on the bed, before he crawled under it to get at the box.

Jim Sankey was the first to shake himself free from him and, seeing what Fullarton was doing, he jumped on to the bed and gave him his assistance and, in half a minute, the ruffian's leg was lashed to the bedpost, at a height of five feet from the ground.

Just as this was done there was a rush of feet outside; and three men, one holding a cutlass and the other two armed with pokers, ran into the room. It was fortunate they did so, for the man whom Bob had first felled was just rising to his feet; but he was at once struck down again, by a heavy blow over the head with the cutlass. By this time the admiral had torn off the bandage across his mouth.

"Another of them ran downstairs, Jackson. Give chase. We can deal with these fellows."

The three men rushed off.

"Well, I don't know who you are," the admiral went on, turning to the boys, "but you turned up at the nick of time; and I am deeply indebted to you, not only for saving my money--although I should not have liked to lose that--but for having captured these pirates.

"That villain has not hurt you much, I hope?" for both Bob and Jim Sankey were bleeding freely, from the face, from the heavy blows the robber had dealt them.

"No, sir, we are not hurt to speak of," Bob said. "We belong to Tulloch's school."

"To the school!" the admiral exclaimed. "What on earth are you doing here, at four o'clock in the morning?

"But never mind that now. What is it, Jackson, has he got away?"

"No, sir; he was lying in a heap, at the bottom of the stairs. There was a lanyard fastened across."

"We tied a string across, sir, as we came up," Bob explained.

"Well done, lads!

"Are there any more of them, Jackson?"

"Don't see any signs of any more, admiral. There are the two plate chests in the passage, as if they had been brought out from the butler's strong room, in readiness to take away."

"Where is the butler? He must have heard the pistol shots!" the admiral exclaimed angrily.

"He is not in his room, admiral. We looked in to bring him with us. The door was open, but he isn't there."

"There is another man in the drawing room, tied." Bob said. "He was putting a lot of things into a sack."

"The scoundrel! Perhaps that is the butler," the admiral said.

"Well, Emma, you had better go back to bed again.

"Jackson, you stand guard over these two villains here, and split their heads open, if they venture to move.

"Now, let us go and see to this other fellow."

The admiral proceeded downstairs, followed by the boys. The other two servants were standing beside the third robber, who was still insensible.

"You keep watch over him, John," the admiral said.

"William, you come with us. There is another man in the drawing room, but he is tied."

"There is the key, sir," Bob said, producing it. "We thought it safest to lock him up."

"Upon my word, young gentlemen, you seem to have
