heard us, but we thought that they might see the white shirt flying up and down. The boat was tacking a long leg and a short one. The long one carried it so far out that we thought it was going to cross the mouth of the bay and not come near enough to see us. Jerry stopped shouting just long enough to gasp:
"When she's all ready to go about on the short tack is the time to yell loudest."
But the next short tack seemed to bring the boat no nearer than before, and the long leg carried it so far away that it was no more use shouting to the orange sail than to a stupid old herring-gull.
"Could you wave for a bit, Chris?" Jerry said. "My arms are off."
So I took the shirt and waved it by its sleeves, and the catboat began another short tack. It was just then that we saw something black flap-flapping against the sail.
