Chet and Biff were nowhere to be seen, so the Hardy boys assumed that they were still fishing.
"When we tell them all the adventures we've had, they'll be as mad as hops," laughed Frank.
"We've sure covered a lot of territory since they last saw us."
"And the day isn't over yet. We still have Captain Royal to attend to."
It was still damp and foggy as they went on down the beach, and although it was midday the mist hung so heavily over the sea that they could see only a short distance ahead. It was almost as dark as at dusk.
"I believe the fog is growing worse," remarked Frank.
"It certainly seems worse since we've got down on the shore again."
"I hope Chet and Biff don't get lost."
"Not much danger of getting lost around here. It's pretty hard to get far from the ocean, and once you're on the beach you just have to keep walking until you find the caves."
The boys came to the place where they had spied Carl Schaum in his drunken slumber.
