"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."
There is not much excitement in a sailing race, as the boys very soon found out. There was nothing they could do, which would have been the case in a motor craft, to add to their speed. All they could do was to sit and let the wind carry them. And they were glad to see that the breeze was continually freshening.
"There'll be another gale before night, if this keeps up," predicted
Frank.
"Let it," assented Andy. "The Gull likes heavy weather, and we can stand it."
"Yes, but father and mother will be worried about us. If it comes on to blow too hard we'll have to turn back."
