"Why, you have already," cried Dick. "I say, are you tired? Shall I help you now?" "Tired? No, lad, not us. No. There, you keep your eye on that old chimney. Tell him, Will, how to find the ground." "All right!" said Will. "Well, you see that pile of stones on the top of the hill behind the chimney to the right?" "What, a rough bit like a lump of sugar on a loaf of bread?" "That's it!" said Will. "Now, you see those, as we row out, seem to grow closer together?" "Yes, I see, because you're getting them more in a straight line." "To be sure!" said Will. "Well, then, when we get them exactly one in front of the other, they give us our bearings one way." "Oh!" said Dick. "Now, look yonder at that church tower at Gullick," said Will. "Yes, I see it." "There's a big tree on the hill to the left of it." "Six," said Dick. "No, no, not that clump; but that one standing by itself." "Yes, I see." "Well, when the church is right before that tree it gives us the bearings the other way." "I think I see," said Dick dubiously; "but I'm not sure." "It's easy enough," said Will. "You'll soon see. Now look out--the mine chimney over the cairn, and Gullick church in front of the big tree, and there we are right on our fishing-ground." They rowed on for another quarter of an hour, watching the chimney and church, which seemed to glide more and more over the distant points till, full of excitement as he began to comprehend more fully the little simple problem learned by fishermen without instruments or books, he waited till he thought that the various points must be exactly coinciding, and called out to those who were rowing behind him as he looked over the stern: "It's now, isn't it--now?" "Now it is," said Josh, as there was a splash in the water and the rattling of a rope over the gunwale. Dick had well learned his first lesson in taking bearings, and called out at the exact moment, just as Josh was in the act of throwing over the little anchor and buoy, to which the long-line, or "bolter," was to be made fast. Here is the problem in mathematical lines: Which being explained is that A represents the old mine chimney, B the cairn, C Gullick Church, and D the tree. The boat was rowed till A and B were in a straight line, and C and D were also in a straight line. This would place the boat at E, the fishing-ground, which they could always find by these simple means. CHAPTER TWELVE. THE CATCHING OF MANY FISH, AND THE GETTING CAUGHT THEMSELVES. It was a glorious evening, the aspect of the bay being grand, lit up as it was by the golden light of the setting sun. Distant windows glowed like fire; the rugged Cornish hills were like amber; and sea and sky were gorgeous with brilliant hues. "Oh! I do like this!" cried Dick. "I wish poor old--but you will bring him next time. Now, then, what shall I do?" "Sit still," said Josh gruffly, "and see him pay out the line."
