And away he rushed below, leaving Ralph and Rory looking so comically puzzled that McBain burst out laughing.

“Is it leave of his seven senses,” said Rory, seriously, “that poor Allan is after taking? And can you really laugh at such an accident, Captain McBain? it’s myself that is astonished at you?”

“Ah! but lad,” said McBain, “I’m in the secret.”

Allan was on deck again in a minute.

He was waving a basket aloft.

“Helen’s pigeon, boys! Helen’s pigeon!” he was crying, with the tears actually in his eyes. “I’d forgotten Peter had it till now.”

Ten minutes afterwards the tiny missive, beginning “At sea” and ending “All’s well,” was written, and attached to the strong bird’s leg. It was examined carefully, and carefully and cautiously fed, then a message was whispered to it by Rory—a message such as a poet might send; a kiss was pressed upon its bonnie back, and then it was thrown up, and almost immediately it began to soar.

“The bravest bird that ever cleaved the air,” said Allan, with enthusiasm. “I’ve flown it four hundred miles and over.”

In silence they watched it in its circling flight, and to their joy they saw it, ere lost to view, heading away for the distant mainland of Scotland. Then they resumed walking and talking on deck.

That was about the only incident of their first day at sea. Towards evening a little stranger came on board, and glad he seemed to be to reach the deck of the Snowbird, for he must have been very tired with his long flight.
