"Why, there's one on!" cried Arthur excitedly.

"Small pollack," said Will smiling. "Haul him in."

Arthur forgot all about the wetness of the line this time, and soon drew one of the brightly coloured fish inboard and called to his brother.

"Here, look!" he cried, "you never saw anything so beautiful as this."

"Just like mine," cried d.i.c.k, "only it was ten times as big."

"Oh!" said Arthur in a disappointed tone. Then, in a whisper to Will, "I say, boy, put on a big bait this time. I want to catch a large one."

Will felt amused at the other's dictatorial importance, but he said nothing: placing a bait on the hook, and the line was once more trailed behind, but this time without success, and at the end of a few minutes the boat was guided into a narrow pa.s.sage amongst the rocks, below a high forbidding headland where the long slimy sea-weed that clung to the granite was washing to and fro, as the waves rushed foaming in and out among the huge blocks of stone, some of which were every now and then invisible, and then seemed to rise out of the sea like the backs of huge s.h.a.ggy sea-monsters playing in the nook.

Josh had taken the oar from d.i.c.k, and had now a.s.sumed the sole guidance of the boat, rowing slowly with his head turned towards the sh.o.r.e, and once or twice there was a sc.r.a.ping, b.u.mping noise and a jerk or two, which made Arthur seize hold of the side.

"Is it safe to go in here?" said Mr Temple.

"Oh! you may trust Josh, sir," exclaimed Will. "It wouldn't be safe at high water, but there's no danger now."

"Not of getting a hole through the boat?"

"Boomp--craunch!"

Arthur turned quite white, while d.i.c.k laughed.

"That's only her iron keel, sir," said Will, for Josh was too intent upon his work to turn his head for answer. "The wave dropped us on that rock, and we slid off, you see, on the keel. Now we're in deep water again."

The action of the waves close insh.o.r.e on that rugged coast, even in that calm weather, was sufficient to raise them up three or four feet and then let them down, while the water was so clear that they could see the weeds waving and streaming here and there over the tinted rock, patches of which, where they were washed bare, were of the most brilliant crimsons, purples, and greens.

Josh was guiding the boat in and out along a most intricate channel, now almost doubling back, but always the next minute getting nearer to a beautiful white patch of strand, beyond which was a dark forbidding clump of rocks piled-up in picturesque confusion, and above which the gaunt cliff ran up perpendicularly in places till it was at least three hundred feet above their heads, and everywhere seeming to be built up in great blocks like rugged ashlar work, the joints fitting closely, but all plainly marked and worn by the weather.

"Sit fast all!" said Josh; "here's a wave coming!"

He gave one oar a sharp tug to set the boat's head a little farther round, and Arthur sprang up and with a sort of bound leaped to his father's side, clinging to him tightly, as a loud rushing, hissing sound rose from behind, and a good-sized wave came foaming in and out among the great blocks of stone, as if bent on leaping into and swamping the boat; but instead of this, as it reached them it lifted the boat, bore it forward, b.u.mping and sc.r.a.ping two or three rocks below the keel, and then letting it glide over the surface of a good-sized rock-pool, swirling and dancing with the newly coming water.

Josh then rowed steadily on for a few strokes, pausing by some glistening rocks that, after lying dry for a few hours, were being covered again by the t.i.tle.

"Your young gents like to look at the dollygobs, master?" said Josh.

"Look at the what!" exclaimed Mr Temple.

"Them there gashly things," said Josh, pointing to a number of round patches of what seemed to be deep-red jelly, with here and there one of an olive green.

"Sea-anemones, boys," said Mr Temple. Then to Josh, "No, they must hunt them out another time; I want to land. I suppose we can climb up to that shelf?"

He pointed to a flat place about a hundred feet above them.

"Dessay we can, if it arn't too gashly orkard," growled Josh. "If she be, we'll bring the rope another time and let you down. Sit fast again!"

For another wave came rushing in, seeming to gather force as it ran, while Josh so cleverly managed the boat that he made it ride on the surface of the wave right over a low ridge of rocks, and then rowed close in and ran her head upon what looked to be coa.r.s.e sand. Then in went the oars, Josh and Will leaped out, waited a few moments, and then, another smaller wave helping them, they drew the boat higher, so that she was left half dry, and her pa.s.sengers were able to step out on the dry patch beneath the rocks.

"Why, it isn't sand, but little broken sh.e.l.ls," cried d.i.c.k excitedly, as Mr Temple casually picked up a handful to examine.

"Yes, d.i.c.k, broken sh.e.l.ls, and not siliceous," said Mr Temple.

"What are those red and green rocks, father?" asked d.i.c.k.

"Serpentine; and that white vein running through is soapstone. Ah! now we shall get to know a little about what is inside."

"But why have we come here?" asked Arthur.

"Because there has been a working here. Some one must have dug down and thrown out all that ma.s.s of broken rock. Part has been washed away; but all this, you see, though worn and rounded by the waves washing it about, has been dug out of the rock."

He had walked to a long slope of wave-worn fragments of rock as he spoke, forming a steep ascent that ran up into a rift in the great cliff; and he drew d.i.c.k's attention to the fact that what seemed like a level place a hundred feet above was so situated that anything thrown down would have fallen in the niche or combe of the cliff just beyond them.

"Now, my fine fellow," said Mr Temple, as he picked up a piece of wave-polished stone, "what's that?"

"Serpentine," said Will quietly.

"And this?" said Mr Temple.

"Granite, sir."

"Eight; and this?"

"Gneiss," replied Will.

"Quite correct. Now this," he continued, breaking a piece of stone in two with his hammer.

"Cop--no, only mundic," cried Will, who had nearly been caught tripping.

"Right again. Now this?"

He picked up a reddish piece of stone which, when broken, showed bright clear crystals, and close to the ruddy stone a number of little black grains.

"Tin," cried Will eagerly; "and a rich piece."

"Let me look at the tin," cried Arthur eagerly; and the piece being handed to him, "where?" he cried; "there's no tin here."

"Tin ore, my boy," said Mr Temple quietly. "Those black grains are rich tin."

"Well, I shouldn't have thought that," said Arthur; "and I should have thought that was gold or bra.s.s."

"Then you would have thought wrong," said Mr Temple sharply. "All is not gold that glitters, my boy; and you can't find bra.s.s in the earth.

What can you find, my lad?" he continued, turning sharply to Will.

"Copper, sir, and tin and zinc."

"Then what is bra.s.s?" said Mr Temple.
