'It makes me feel quite lively again to think of it,' exclaimed Calladon, springing to his feet. 'Only,' he added, 'that is one of the things the Master told us not to do.' 'Oh, I don't believe the Master would mind,' said Callia. 'Besides, how should he ever know anything about it? He has gone away.' 'Of course, too, it is our own affair,' observed Calladon. 'If any harm comes of it, it will be to ourselves, and not to him.' 'I am not afraid,' said Callia. 'Are you?' 'Not in the least. By the way, though, I am not sure that I know the way out of Abra. There doesn't seem to be any door.' 'I think I can find the way, if that is all,' returned Callia. 'I don't know how I happened to think of it--but since we have been talking about going, it has seemed to me that if we were to push against that little carved knob in the wall, it would open a passage into the room outside. Shall we try it?' 'Yes,' said Calladon; 'it can do no harm to see whether you are right, at all events.' So they went to the knob, and Calladon gave it a push. 'Not that way; you should push it sideways; see--like this,' said Callia; and she shoved it a little towards the right. Sure enough, a part of the alabaster wall slid back, so that the children were able to look into the room beyond. 'It seems rather dark; don't you think so?' remarked Calladon, drawing back after a moment. 'We must take a lamp along with us,' said Callia. 'That lamp that burns in the centre of the room will be no use to us. We shan't be able to see anything without a lamp of our own.' 'Well, I suppose we must,' said Calladon. 'Now I think of it, though, that was another of the things the Master said we ought not to do.' 'What did he say would happen to us if we did do it?' 'I don't remember his saying anything.' 'Of course he didn't! because nothing will happen, except that we shall know more than we could know by staying here. He was only trying whether he could frighten you.' 'You shall see that I am not so easily frightened,' said Calladon. 'I am a man now, and able to take care of myself. Come, let us light a lamp of our own and go. I will show you the way.' 'Here is a lamp,' said Callia. 'I just found it on this little shelf in the corner, though I had not seen it there before. But how shall we light it?' 'We must light it from the great lamp; there is no other way.' 'But then it will be the light of that great lamp that will guide us, after all.' 'No,' said Calladon, 'because the part of the flame that we take away will become our own, and would keep on burning even if the great lamp were to go out.'
