We were proceeding so gently that she as well as I had hopes that I might be able to actually balance the machine on the top of the curving wall--a thing manifestly impossible on a straight surface, though it might have been possible on an angle.
On we crept--on, and on! There was no sign of light about the Tower, and not the faintest sound to be heard till we were almost close to the line of the rising wall; then we heard a sound of something like mirth, but muffled by distance and thick walls.

From it we took fresh heart, for it told us that our enemies were gathered in the lower chambers.

If only the Voivode should be on the upper stage, all would be well.
Slowly, almost inch by inch, and with a suspense that was agonizing, we crossed some twenty or thirty feet above the top of the wall.

I could see as we came near the jagged line of white patches where the heads of the massacred Turks placed there on spikes in old days seemed to give still their grim warning.

Seeing that they made in themselves a difficulty of landing on the wall, I deflected the plane so that, as we crept over the wall, we might, if they became displaced, brush them to the outside of the wall.
