As a consequence, the report had gone forth that the supposedly extinct volcano had become active again, and its neighbourhood was shunned as dangerous by all not in the secret. A few venturesome inquirers, who had attempted to make explorations, had been baffled by the sulphur fumes, and had returned declaring that there were evident signs of renewed volcanic activity.
Similarly, if, as sometimes happened, an occasional airship, driven out of her course by high winds, passed near the place at night, and saw a light coming up through the opening, it was put down to the same cause.

These notes are necessary to explain the events which follow.

The mist seemed to grow thicker as the adventurers sailed cautiously onwards, and it soon became obvious that they would quickly have lost themselves if they had not had Fumenta to guide them. He, however, seemed to know his way about in it with as much certainty as if it had been clear. He was aided, no doubt, by a dim radiance which struggled down from the moon above.

He led off to the right, mounting always upwards, till, after they had travelled perhaps a mile, he brought them to a halt beside a towering peak.
'Here,' he said, in low, guarded tones, 'you had better rest for a little time, while I reconnoitre from the top of the mountain, which rises yet some hundreds of feet into the air. It is one of the highest peaks about here, and these occasional ground-mists scarcely ever reach its top. It may be that we can get a view from its summit over the top of the mist, but at the same time we shall run some risk of being seen ourselves. Let me, therefore, make the trial first, as I am more used to this kind of thing than you are. I will return in a short time and let you know the result. Do not leave this spot, and, whatever you do, do not talk loudly. Voices travel far in this mist; you cannot tell how near our enemies may be.'
With that he started off, mounting silently upwards, and the four he left behind began discussing their recent adventures, and the possible future, in low tones.
'So that's the great outlaw chief!' said Jack. 'What do you think of him? I suppose he is to be trusted? I must say I am agreeably surprised! I like his looks; yet one never knows! He might betray you, Prince, to your enemies. How if he could buy off Agrando's hostility that way? It might be a great temptation!'
