"I think, Master Vickars," one of them, Roger Browne by name, said, "that I had best go up first. I served for some years at sea, and am used to climbing about in dizzy places. It is no easy matter to get from this window sill astride the roof above us, and moreover I am more like to heave the grapnel so that it will hook firmly on to the ridge than you are." "Very well, Roger. I should be willing to try, but doubtless you would manage it far better than I should. But before you start we will fasten the other rope round your body, as Captain Vere directed me to do. Then in case you slip, or anything gives way with your weight, we can check you before you slide far down below us." A rope was accordingly tied round the man's body under his arms. Taking the grapnel, to which the other rope was attached, he got out on to the sill. It was not an easy task to climb up on to the ridge of the dormer window, and it needed all his strength and activity to accomplish the feat. Once astride of the ridge the rest was easy. At the first cast he threw the grapnel so that it caught securely on the top of the roof. After testing it with two or three pulls he clambered up, leaving the lower end of the rope hanging by the side of the window. As soon as he had gained this position Geoffrey, who was to follow him, prepared to start. According to the instructions Browne had given him he fastened the end of the rope which was round Browne's body under his own shoulders, then leaning over and taking a firm hold of the rope to which the grapnel was attached, he let himself out of the window. Browne hauled from above at the rope round his body, and he pulled himself with his hands by that attached to the grapnel, and presently reached the top. "I am glad you came first, Roger," he said. "I do not think I could have ever pulled myself up if you had not assisted me." He unfastened the rope, and the end was thrown down to the window, and Job Tredgold, the other man, fastened it round him and was hauled up as Geoffrey had been. "We will move along now to that stack of chimneys coming through the roof four feet below the ridge on the town side," Geoffrey said. "We can stand down there out of sight of the Spaniards. We shall be sure to attract attention sitting up here, and might have some bullets flying round our ears, besides which this fellow's friends might suspect our object and signal to him in some way. It is two hours yet to the time when we have twice seen him send his bolts across the moat." This was accordingly done, and for an hour and a half they sat down on the roof with their feet against the stack of chimneys.
