"When shall we catch her up?" asked Blair anxiously.

"Perhaps by three o'clock or so," said Cathie, after a moment's consideration, but added cautiously, "if the wind holds," and, as if resenting his doubt, the sails gave an ominous warning flap.

"Right," said the captain, with a determined nod, and set the engineers to work at once to get up steam. "We'd be as well to have it on anyhow, to keep the weather gauge of him when we come up," and presently the screw was churning the merry bubbles up astern, and the chase was rising slowly on the horizon.

The brig, however, had held the wind longer than they had. It was mid-afternoon before they got within range of her, and she was still drawing slowly along with sails that bulged and flapped in desultory catspaws.

"Shall I send a shot over her, just to show we mean business?" brimmed Cathie.

"No shots unless they're absolutely necessary, captain," said Blair. "We'll hail her first. And I think you ladies had better go below. Their answer may be lead."

Aunt Jannet was for resisting.

"I want to see," said she.

"There may be things not for your seeing, Aunt Jannet," said Blair quietly, "and other things besides. Please go with the others and keep them from feeling nervous if you can."

So the ladies went below, and we may imagine to what helpful furtherance of patient waiting they betook themselves.
