"So! Bring up the able-bodied, and make for yon summer-house; you see!--a yard or two away. Wait for me there."

Mackenzie crept silently away: he never wasted words. Not till afterwards did Forrester learn how the patient Scotsman had prowled about the grounds nightly in order to guard against the contingency that had actually happened--the sudden appearance of the prisoners above ground. Hamid Gul had accidentally dropped the string down the grating when trying to tie it to a bar, and having no more to spare, could neither send nor receive a message.

Forrester withdrew his head, and set to work to enlarge the hole for the passage of his shoulders. It was an unexpectedly slow process. He dared not hack vigorously for fear of bringing a mass of earth tumbling in upon him, or of piercing the embankment and letting down a deluge. But he picked away patiently until the gap was large enough to scramble through.

Then he gave the long-awaited word, and heaved himself to the surface. In spite of his care, a chunk of earth broke from the edge and fell down the chimney, breaking and scattering on the bamboos laid across the slab. Beresford waited a moment or two; then he mounted, without accident, and after him Wing Wu. The three men crouched near the hole, waiting for Chung Tong to appear. It seemed that he would never come. Time was flying; the dawn could not be far off. Presently they heard an ascending scale of sighs as the Chinaman, pricked by fear of loneliness to follow them, climbed the bars one by one, each upward move accompanied with a sigh. When his head emerged, Forrester and Beresford caught his shoulders, and heaved him through, not without disturbing clods that fell with ominous thuds, just audible, on the screen.

Forrester lead the way stealthily to the summer-house indicated by Mackenzie. There Mackenzie and Jackson, with Hamid Gul, were awaiting them. For a few moments speechless greetings passed between the reunited friends; their hearts were full; feeling was too intense to find expression in word. When Mackenzie at last spoke, there was an unusual huskiness in his tones.

"Come now, listen, all of you. We are in a garden; there's a seven-foot wall around it. Beyond the wall is a larger enclosure. That's where the buildings are. Dick, you and I are going through Hamid's quarters and the kitchen into the pagoda. We are going to collar the Eye!"

A thrill shook them all.

"Hamid knows where it is. If we canna do it, we capture the Old Man, and hold him as a hostage. There's a sentry in the antechamber leading to his apartments. There's another at the principal outer door, which opens to the enclosure yonder. They're likely fast asleep. We'll no meddle with the man at the principal door. The other--we'll have to deal with him. If there's an alarm, the rest of ye just bolt for yon door, and do your best to hold it against the priests. If the sentry has gone inside, one or two of ye follow him up. You've got arms of a sort: you can change 'em for the two-three things we've brought if you like 'em better. It's touch and go, ye ken. We must be swift and sure. We canna fight hundreds; but with yon old de'il's Eye in our possession, we can defy him and his priests too. Bob, you'll be in charge here, and this gentleman--Mr. Beresford, I presume--will likely give you every assistance."

"You may be sure of that," said Beresford.

"Well, that's all. We'll shed our boots. Then, Hamid, lead the way."
