“You get yours first, and then relieve me. I don’t want to eat with one hand and steer with the other. Only don’t be all morning, and leave some for me.”

There was enough, as Frank soon discovered, and when he came up on deck again he found Andy leaning against the tiller and peering at the distant vessel through the binoculars.

“Can you make out anything?” he asked.

“No, I can see several men aboard, but I don’t notice our mysterious friend.”

“Do they seem to be paying any attention to us?”

“Not a bit. Guess they don’t even know we are here. I don’t believe we are going to catch up to them, though.”

“Oh, yes we are. The Gull is plenty fast, and they are handicapped by dragging that motor boat in the water. It must be partly filled, as it sets so far down, and that makes it all the harder to tow. We’re gaining on them.”

“Not so’s you could notice it.”

“Oh, well, we’ve got all day, and grub enough for another night. I’m not going to give up this chase until I have to, or until I’ve solved the mystery.”

“And I’m with you.”
