“I haven’t got the rope.”

“My: what a head I have!” cried Jem, as Don tightly knotted the rope about his waist; and then, mounting on his companion’s back once more, was borne very slowly, steadying himself by the sloping roof, till the window was reached.

“Hold fast, Jem.”

“Right it is, my lad.”

There was a clicking of the iron fastening, the window was thrust up higher and higher, till it was to the full extent of the ratchet support, and then by passing one arm over the light cross-beam, which divided the opening in two, Don was able to raise himself, and throw his leg over the front of the opening, so that the next minute he was sitting on the edge with one leg down the sloping roof, and the other hanging inside, but in a very awkward position, on account of the broad skylight.

“Can’t you open it more?” said Jem.

“No; that’s as far as the fastening will hold it up.”

“Push it right over, Mas’ Don, so as it may lie back against the roof. Mind what you’re doing, so as you don’t slip. But you’ll be all right. I’ve got the rope, and won’t let it go.”

Don did as he was told, taking tightly hold of the long cross central bar, and placing his knees, and then his feet, against the front of the opening, so that he was in the position of a four-footed animal. Then his back raised up the hinged skylight higher and higher, till, holding on to the cross-bar with one hand, and the ratchet fastening with the other, he thrust up and up, till the skylight was perpendicular, and he paused, panting with the exertion.

“All right, Mas’ Don; I’ve got the rope. Now lower it down gently, till it lies flat on the slope. That’s the way; steady! Steady!”
