“Then we’ll have a stronger light,” said Mr Temple. “Open that lantern, Dick.”

The boy obeyed, and his father ignited the end of a piece of magnesium wire, which burst out into a brilliant white light, showing them the roof and sides of the narrow cave, flashing off the water, and, what was of greater interest still, displaying the heads of a couple of seals raised above the surface at the end of the channel, and the dark-grey shiny body of another that had crawled right into a rift but could get no farther, and was now staring timidly at them.

The light sputtered and glowed, and dense white fumes floated in a cloud above their heads, while the boat was urged softly closer and closer towards the seals, the effect being that as the animals saw the light and the curious objects beneath advancing towards them the two in the water swam to the end and began to crawl out upon the rock, forcing themselves towards their companion in the rift.

“Go right on, sir?” said Will in a low voice.

“Yes. Close on, my lad,” said Mr Temple. “Have a good look at them, boys, before they go.”

“You’re not going to catch one, are you, father?”

“Oh no! We’ll have a good look at them. Wild creatures are getting far too scarce about the coast as it is.”

He kept manipulating the wire as he spoke, sparks and incandescent pieces falling the while with a loud hiss in the water, making Arthur start till he was prepared for what was to come. And as Mr Temple managed the light and stood up in the boat its pale dazzling rays made the cave as light as day; and at last they were within three or four yards of the seals, which suddenly, after gliding and shuffling one over the other in utter astonishment, made Arthur and Dick start back, falling over into the bottom of the boat.

For, evidently frantic with dread, and helpless as far as relief was concerned, the three seals, as if moved by one idea, gave a wallowing movement, and dashed from the rocks together, seeming for the moment as if they were bent on leaping into the boat, but of course falling short and plunging into the water with a tremendous splash, which sent the spray all over those who were nearest; and at the same moment there was a hiss, and they were in total darkness.

“I won’t be afraid,” said Arthur to himself; and he clenched his teeth as his father said loudly:
