“Oh, if I had a gun,” cried Pradelle, to hide his confusion.

“What for—to make a miss?” sneered Harry. “Now then, out with those cans. Fill every one, and I’ll try and knock off a few anemones for the governor.”

As he spoke he laid in his oars, picked a hammer and chisel from out of the locker in the forepart of the boat, and then worked it along by the side of the great cave, as from out of the clefts and crannies above and beneath the water he searched for the semi-gelatinous sea-anemones that clustered among barnacles, and the snail-like whorl molluscs whose home was on the weedy rocks.

The girls aided all they could, pointing out and receiving in the tins a many-rayed creature, which closed up till it resembled a gout of blood; now, still adhering to the rock which Harry chipped off, a beautiful Actinia of olive-green with gem-like spots around the mouth and amid its fringe of turquoise blue.

Duncan Leslie eagerly lent his help; and, not to be behindhand, Pradelle took up the boat-hook and held on, but with the smoothness and care of a sleek tom-cat, he carefully avoided wetting his hands.

“Nothing very new here,” said Harry at last, as the waves that kept coming in made the boat rise and fall gently; “there’s another better cave than this close by. Let’s go there; or what do you say to stopping here and having a smoke till the tide has risen and shut us in?”

“Is there any risk of that?” said Pradelle anxiously.

“Oh, yes, plenty.”

Leslie glanced at Louise and thought that it would be very pleasant to play protector all through the darkness till the way was open and daylight shone again. He caught her eyes more than once and tried to read them as he wondered whether there was hope for him; but so surely as she found him gazing rather wistfully at her, she hurriedly continued the collecting, pointing out one of the beautiful objects they sought beneath the surface, and asking Pradelle to shift the boat a little farther along.

“All my vanity and conceit,” said Leslie to himself with a sigh; “and why should I worry myself about a woman? I have plenty to do without thinking of love and marriage. If I did, why not begin to dream about pleasant, straightforward Madelaine Van Heldre? There can be nothing more than a friendly feeling towards Master Harry here.”
