It is easy enough to start a fire, you know: the difficulty is to limit its action and put it out when you wish!" "Oh, there's no fear about that," replied Eric with great nonchalance.
"The wind is blowing from the north-east and will only carry the flames against the cliff, where there is nothing to harm." Was there not?
Higher and higher rose the smoke, ascending pyramidically up the chimney-like gorge; and, the quick-darting tongues of flame could be seen spreading through the hazy veil, while the crackle and roar of the fire sounded fiercer and fiercer.

Presently, growing bolder in its strength, the fire advanced outwards from the cleft in the rock where it was first kindled, spreading to the right and left of the gully.

Next, it began to clamber up the face of the cliff, burning away gaily even right under the waterfall, which seemed powerless to stay its rapid progress.
"Look, Eric," cried Fritz, "it has caught the tussock grass now close to our ladder.

I told you it would do mischief!" "Bother it all, so it has!" exclaimed the lad, darting off with the vain intention of trying to stop the conflagration.
He might just as well have attempted to arrest the flow of the sea in the little bay below by the aid of his much-detested spade! Crackle, crackle--puff--whish; and, in another few moments, the whole cliff seemed on fire, the flames licking every particle of herbage off the face of the rock.
The heat soon made the solid stone glow like molten iron; while the columns of white smoke, as they rose up, were swept by the wind over the tableland, frightening away several of the albatross, which hovered over the scene of devastation on poised wing, wondering apparently what all the fuss was about! The fire gradually burnt itself out when there was nothing more to consume, only an angry pile of smouldering embers remaining below the waterfall, which still danced and tumbled itself over the blackened edges of the crags, no longer festooned with the tussock-grass and shrubs which had previously given the brothers handhold and foothold when climbing to the summit of the cliff.
The ladder up to Eric's look-out station being now irremediably destroyed, henceforth the sphere of action of the brother crusoes would be limited to the confined valley in which they had landed and built their home; for, there was now no means of reaching the tableland, save by the pass on the western side near their sealing station, to reach which they would have to use the whale-boat and venture out to sea, round the eastern or western headland.
They were now really shut completely within their little valley, without a chance of escaping in any sudden emergency, except by taking to the water! The destruction of the ladder-way was a sad calamity; but, that was not the worst of the damage done by Eric's bonfire! It was late in the afternoon when the lad first lit up the pile of rubbish and night came ere the fire had died out, its blazing light, reflected back by the glistening surface of the cliff, shining out to sea from the bay, like a beacon welcoming the passing mariner to friendly shores--instead of which, the cruel crags that encircled the island only grinned through the surf, like the pointed teeth of a pack of snarling wolves, waiting to rend and tear any hapless craft that should make for them! In addition to this, there was yet another peril to any ship in the vicinity; for, the wind from the north-east had risen to a gale as the evening set in, bringing with it a heavy, rolling swell that thundered in upon the beach with a harsh, grating roar, throwing up columns of spray over the projecting peaks of the headlands on either hand.
"I hope no vessel will mistake your bonfire for a beacon," said Fritz, as the darkness increased.

"If so, and they should chance to approach the land, God help them, with this wind and sea on!" "I trust not," replied Eric sadly, already regretting his handiwork; "it would be a bad look-out for them!" But, as he spoke the words, the sound of a cannon could be heard coming from seaward over the water; and the lad shuddered with apprehension..
