“Ha! ha! ha!” shrieked little Magnus, “yon’s the answering signal—ha! ha! ha!”

At the same moment down went the flag of distress, and up went the black flag that pirates like to display when they really mean mischief. Something else went up at the same time, namely, Captain McBain’s Highland blood. This is no figure of speech; you could have seen pride and anger mantling in his cheek and glancing like fire from his eye.

“The black flag, indeed!” he growled; “only cowards hoist it; they think it startles their would-be prey, like the hiss a cat or a goose emits, or the images and figures idiot savages carry in their battle-van. They will not frighten us. Stevenson, load the six-pounder Armstrong. Lucky we took that little tool with us. Tell Ap to see to the small arms. We’ll show them the metal we’re made of ere we surrender the Snowbird. Stand by tacks and sheets, we’ll put her before the wind. A stern chase is a long chase; we may give her the slip after nightfall.”

There was a cheeriness in McBain’s voice as he spoke, that communicated itself to all hands fore and aft. There was no bombast about the captain, mind you, no vulgar jingoism. He merely meant to hold his own, even if he had to fight for it.

All sail was set that the Snowbird could carry, both below and aloft, an example that was speedily followed by the pirate, for pirate she seemed, from her bunting, to even brag in being, and so the chase began in earnest. The stranger fired once or twice only, but the shots falling short she gave it up, and concentrated all her attention in endeavouring to get within reach.

For the next hour there was silence on board the Snowbird, except for some brief words of command given in quiet quick tones, and just as speedily obeyed. Rory, Ralph, and Allan were clustered astern, watching the pirate. This was a kind of danger to which they had never dreamed they would be exposed; yet still the confidence they had in brave, cool McBain banished all fear from their hearts.

But the captain’s anxiety was extreme, and his eyes roved incessantly from the Snowbird to the vessel in chase, not without many a glance at the fast-declining sun.

“Are we quite prepared?” he asked Stevenson.

“All ready, sir,” was the reply, with an uneasy glance astern, “but I think she is coming up, sir, hand over hand and now she is actually setting stunsails.”

“Then God help us, Stevenson, for that chap is bound to win the battle if he can only win the race.”
