"There's a way out there.

Look, fellows! See where it says 'Drawbridge'?
Evidently you can get through there into the Squam River, and the river takes you out into Ipswich Bay! It's dollars to doughnuts that's where they took the _Follow Me_!" Steve drew down the throttle and the cruiser lunged forward in response.
"We'll have a look, anyway," he said.

"It was stupid of me not to have noticed that on the chart, but it's hardly big enough to be seen." Straight for the beach at the curve of the wide cove sped the _Adventurer_, her nose set for the drawbridge that showed against the blue sky.

As they got closer an outlet showed clear, a narrow space between the bridge masonry, with a strong current coming through from the further side.
"Gee, it doesn't look very big," said Joe.

"And how about head-room, Steve ?" "Room enough," was the answer, as the _Adventurer_ slowed down.
