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 title.

"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 coarse 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 passengers were able to step out on the
dry patch beneath the rocks.

"Why, it isn't sand, but little broken shells," cried Dick excitedly, as
Mr Temple casually picked up a handful to examine.

"Yes, Dick, broken shells, and not siliceous," said Mr Temple.

"What are those red and green rocks, father?" asked Dick.

"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 mass 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 Dick'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 nic
