"How's that, Stewart? Have you been teaching your girl navigation?"

"I hadn't a thing to do with it. It's all due to the good friends who have been looking after her while I'VE been shooting up targets. But Polly's right. She CAN handle a craft and so can this little redhead," laughed Captain Stewart, pulling a lock of Polly's hair which the frolicsome wind had loosened.

"By Jove, let's test it. Not many girls can do that trick. Coxswain, turn over the wheel to this young lady, but stand by in case you're needed."

The coxswain looked a little doubtful, but answered: "Aye, aye, sir."

"Oh, ought I?" asked Peggy.

"Get busy, messmate," said Captain Boynton.

The next second the girl was transformed. Tossing her big hat aside and giving her hair a quick brush, she laid firm hold upon the wheel and instantly forgot all else. Her eyes narrowed to a focus which nothing escaped, and Stewart gave a little nod of gratified pride and stepped back a trifle to watch her. Captain Boynton's face showed his appreciation and Polly's was radiant. The old coxswain muttered: "Well, well, you get on to the trick of that, lassie. You might have served on a man-o-war."

They were now well out in the river and making straight for the railway bridge. Peggy alert and absorbed was watching the current as it swirled beneath the arches. "How does the tide set in that middle arch, coxswain?" she asked.

"Keep well to starboard, miss," he answered.

Peggy nodded, and gave an impatient little gesture as a lumbering power boat, outward bound seemed inclined to cut across her course. "What ails that blunderbuss? I have the right of way. Why doesn't he head inshore?" and she signalled sharply on her siren to the landlubber evidently bent upon running down everything in sight, and wrecking the tub he was navigating. Then with a quick motion she flicked over her wheel and rushed by, making as pretty a circle around him as the coxswain himself could have made. "Holy smoke, but ye have given him the go-by in better shape than I could myself. Whoever taught ye?"
