Anna, who knew the ways of this most doubting of Thomases, pulled a piece of paper from her satchel and passed it to him to read. It related at some length the sale in a London auction-room of a stuffed Great Auk in imperfect condition for one hundred and fifty pounds.

"That would be pounds sterling!" said Simeon, who was thinking. He had a suspicion that there might be some quirk about pounds "Scots," and was trying to explain things clearly to himself.

"Now, we are going to the Glistering Beaches to look for the Great Auk!" said Anna as a climax to the great announcement.

The water lappered pleasantly beneath the boat as Simeon deftly drew it over the sea. There is hardly any pleasure like good oarsmanship. In rowing, the human machine works more cleanly and completely than at any other work. Before the children rose two rocky islands, with an opening between, like a birthday cake that has been badly cut in the centre and has had the halves moved a little way apart. This was Stack Canna.

"Do you think that there would be any chance here?" said Anna. The splendour of the adventure was taking possession of her mind.

"Of course there would; but the best chance of all will be at the caves of Rona Wester, for that is near the Glistering Beaches, and the birds would be sure to go there if the people went to seek them at the Beaches."

"Has any one been there?" asked Anna.

"Fishers have looked into them from the sea. No one has been in!" said
Simeon briefly.

The tops of the Stack of Canna were curiously white, and Simeon watched the effect over his shoulder as he rowed.

"Look at the Stack," he said, and the eyes of his companion followed his.
