"They are after a school of pilchards," said Captain Truck.  "See how the water glitters with them; if you look through your glasses at the top of the cliffs, you will see a number of people with boughs in their hands waving them.  They have been on the look-out to give notice as soon as they caught sight of the school.  When they see the first, they sing out `Heva;' but what it means I don't know, except to give notice to the men in the boats."
