"Yes," agreed Mr. Graham. "She's a fairly big craft, too. She'll test our work for us."
Desmond had picked up a telescope, and was examining the on-coming vessel.
"Why, sir!" he announced. "She's a Sea Scout boat. At least she's manned by Sea Scouts. I wonder what she's doing here?"
"The creek's free to anybody," rejoined Findlay. "We're not the only Sea Scouts. I expect they'll land at the Bridge."
Meanwhile Mr. Graham had been making good use of his binoculars.
"I've seen that craft before," he remarked. "Only she was painted grey. I may be mistaken, but I don't think so."
He returned the glasses to their case and picked up his peaked cap.
"Fall in on the quarter-deck, lads," he ordered. "Smartly, now; stand by to give them a full salute when they pass."
The Sea Scouts took up their position as directed, standing easy until the Scoutmaster gave the order: "Alert!"
"She's slowing down, sir," said Findlay.
