"That is correct. Now, if it is one inch from A to B, we may use that inch as a measurement to get the distance along the line."
"Let me step it off," said Harry. "I find it is just two and three-quarters inches."
"What was the distance, in feet from A to B?" asked John.
"I have the figures here," said George. "We found it was six hundred and ninety feet."
"If, now, you will multiply 690 by 2-3/4, we shall have the distance from this point A, and yonder point, or headland C."
"I make it out to be just 1897.5," was Harry's conclusion.
The boys, together with John and a half dozen of the natives, went along the shore, and mounted the point C, and from that place selected another point in a southerly direction, and again made the same calculations.
