"Aye, aye, sir."

The yacht heeled over as she swung.

"South!"

The yacht came to an even keel, swung a point or two back, and steadied.

"South it is."

Far up against the sun a distant film of land blurred the horizon.

"Starboard a little; a little more; keep her at that."

Brand shipped a powerful telescope on slings and focussed the Lands End. There in a trembling mirage the granite city lay, the long glass roofs of her factories gleaming like silver scales.

"Half speed," he murmured; then, as the vessel steadied: "There's the Gigantic—broadside on—starboard a very little—too much—so. Keep her at that. She must be very low down—scarcely a mile above the roofs. She'll see us against the sky, so drop to ten thousand feet, Mr. Simpson."

The Mary Rose fell for a minute or so.
