“Why, he’s creeping in to kill his master,” was the boy’s first thought, and a chill of horror ran through him.

The black crept slowly and silently over the floor of the saloon, and Carey would have uttered words of warning to his companions, but he could not speak, every faculty seeming frozen, save that he could see; and he stared wildly as he saw now two more pairs of eyes and a couple of the blacks creep in silently, but only to stop at the door, squatting on their heels, as if watching their leader.

The latter took up Carey’s whole attention now, and he waited to see him take out his club before he uttered a warning shout to the sleeping man, for he felt that he could not stand and see him murdered in cold blood.

The black crept on till he was quite close to the sleeper, and then he rose, squatted like his companions, and at last raised his hand.

The warning cry rose to Carey’s lips, but it did not leave them, for the black did not bring out his club, but softly took down the empty glass, smelt it and then thrust in a long black finger, passed it round and sucked it, repeating the action several times, till he could get no more suggestion of the taste of the spirit, when he replaced the glass, to sit staring at the bottle; but he did not touch it, only squatted there like a great dog watching over his master, while his two companions remained silent as a couple of black statues at the door.

That was enough, and Carey softly dropped down and whispered what he had seen to his companions.

“And they could brain the old scoundrel at any moment with their clubs,” said the doctor. “It is astonishing.”

“Yes, sir,” said Bostock, softly; “but aren’t it a bit like big savage dogs as I’ve seen? They could take a man by the throat and shake the life out of him in a minute, but they don’t. They sits and watches over him, and it’d be an ugly business for any one as attempted to touch him. He’s got hold of the black fellows, sir, and can do just what he likes with ’em. That’s how it is there.”

“That makes our position more difficult,” said the doctor.

“Well, it do, sir; but if I might make so bold, I should like to propose something.”
