Suddenly Mr Button stopped.
"Whisht!" said he.
Through the silence--a silence filled with the hum and the murmur of wood insects and the faint, far song of the reef--came a tinkling, rippling sound: it was water. He listened to make sure of the bearing of the sound, then he made for it.
Next moment they found themselves in a little grass-grown glade. From the hilly ground above, over a rock black and polished like ebony, fell a tiny cascade not much broader than one's hand; ferns grew around and from a tree above a great rope of wild convolvulus flowers blew their trumpets in the enchanted twilight.
The children cried out at the prettiness of it, and Emmeline ran and dabbled her hands in the water. Just above the little waterfall sprang a banana tree laden with fruit; it had immense leaves six feet long and more, and broad as a dinner-table. One could see the golden glint of the ripe fruit through the foliage.
In a moment Mr Button had kicked off his shoes and was going up the rock like a cat, absolutely, for it seemed to give him nothing to climb by.
"Hurroo!" cried Dick in admiration. "Look at Paddy!"
Emmeline looked, and saw nothing but swaying leaves.
"Stand from under!" he shouted, and next moment down came a huge bunch of yellow-jacketed bananas. Dick shouted with delight, but Emmeline showed no excitement: she had discovered something.
