There is a mile or so of this subterranean work, and it must have cost a vast deal of money and labor.

The gallery guns command the peninsula and the harbors of both oceans, but they might as well not be there, I should think, for an army could hardly climb the perpendicular wall of the rock anyhow.

Those lofty portholes afford superb views of the sea, though.

At one place, where a jutting crag was hollowed out into a great chamber whose furniture was huge cannon and whose windows were portholes, a glimpse was caught of a hill not far away, and a soldier said: "That high hill yonder is called the Queen's Chair; it is because a queen of Spain placed her chair there once when the French and Spanish troops were besieging Gibraltar, and said she would never move from the spot till the English flag was lowered from the fortresses.

If the English hadn't been gallant enough to lower the flag for a few hours one day, she'd have had to break her oath or die up there." On the topmost pinnacle of Gibraltar we halted a good while, and no doubt the mules were tired.
