ALL felt that they had earned what Scrubb called a “breather“. The Witch had locked the door and told the Earthmen not to disturb her, so there was no danger of interruption for the present. Their first business was, of course, Puddleglum's burnt foot. A couple of clean shirts from the Prince's bedroom, torn into strips, and well greased on the inside with butter and salad oil off the supper table, made a fairly good dressing. When this had been applied, they all sat down and had a little refreshment, and discussed plans for escaping from the Underworld.
Rilian explained that there were quite a lot of outlets by which one could get to the surface; he had been taken out through most of them at one time or another. But he had never gone out alone, only with the Witch; and he had always reached these outlets by going in a ship across the Sunless Sea. What the Earthmen would say if he went down to the harbour without the Witch, and with four strangers, and simply ordered a ship, no one could guess. But most likely they would ask awkward questions. On the other hand the new outlet, the one for the invasion of Overworld, was on this side of the sea, and only a few miles away. The Prince knew that it was nearly finished; only a few feet of earth divided the diggings from the outer air. It was even possible that it had now been quite finished. Perhaps the Witch had come back to tell him this and to start the attack. Even if it was not, they could probably dig themselves out by that route in a few hours—if they could only get there without being stopped, and if only they found the diggings unguarded. But those were the difficulties.
“If you ask me—” began Puddleglum, when Scrubb interrupted.
“I say, ” he asked, “what's that noise? ”
“I've been wondering that for some time! ” said Jill.
They had all, in fact, been hearing the noise but it had begun and increased so gradually that they did not know when they had first noticed it. For a time it had been only a vague disquiet like gentle winds, or traffic very far away. Then it swelled to a murmur like the sea. Then came rumblings and rushings. Now there seemed to be voices as well and also a steady roaring that was not voices.
