Then it suddenly stopped.
'Here goes,' said Hildegarde, cracking her nut as she spoke, and the two pair of eyes peered eagerly into the shell. There lay a neat little roll of tiny blue ribbon. Hildegarde drew it out. It was only an inch or two in length, but on it were clearly printed six words:—
Tap, tiny hammer, till you find.
But where was the tiny hammer? This question did not trouble the children for long. Without speaking, Leonore cracked her nut, disclosing to view, as they expected, a 'tiny hammer' indeed—so tiny that even the little girls' small fingers had difficulty in holding it firmly.
'How can I tap with it?', she was on the point of saying to Hildegarde, when, as she gazed, she saw the little hammer stretch itself out till it grew to an inch or two in length, the silver head increasing also in proportion, so that it was now much easier to grasp it.
'How convenient it would be,' said Hildegarde, 'if we could pack up luggage in the way things are packed into our nuts; but let us be quick, Leonore. I wonder where we should begin tapping.'
'In the corner where we heard the other tapping, of course,' said Leonore. But this did not prove to be the right spot. There was no reply to their summons, and some patience and perseverance were required to prevent their yielding to disappointment.
They had no reason, however, for distrusting their fairy friend, and a new idea struck Hildegarde.
'Leonore,' she exclaimed, 'perhaps we are meant to tap on the wall itself, behind the silk hangings. See, if I hold them back carefully, you can creep in and tap right into the corner.'
No sooner said than done, and this time not in vain. With almost the first blow of the little hammer, a small door in the wall opened inwards, and before them the children saw the first steps of a narrow spiral staircase winding upwards. They fearlessly entered, the little door closing behind them, and began to ascend the steps. It was not dark, for slits in the wall let in from time to time tiny shafts of light; nor was it cold, though where the warmth came from they could not tell.
