"Then you shouldn't call names," said Prue, still very red. "How would you like me to call your father an apricot?"

"I shouldn't mind in the least," answered Mollie, giggling worse than ever. "You don't understand. I'll go away, and I'll explain when I am better."

She seized her sunbonnet, tucked her book under her arm, climbed up the side of the ferny dell, crossed the track, and ran into the wood on the farther side, leaving Prue and Grizzel to finish the squabble between themselves.

"We have eaten too much, that's what's the matter," she said to herself, as she slowed down to a walk and the giggle became less severe. "This hot sun all the time makes one feel crossish."

She came to a halt at the foot of a hollow gum tree, and stooping a little she peered within. It looked shady and cool, its floor powdered with decayed bark mixed with dead leaves—quite clean enough, she decided, to sit upon and rest until her giggles had finally subsided. She crept in, snuggled down comfortably, opened her book, and soon was deep in the adventures of Professor Arrownax, Ned Land, Captain Nemo, and the rest.

The shadows swung slowly round, the sun climbed higher and higher, and the day grew hotter and hotter, but Mollie, skimming along the bottom of the sea in the Nautilus was oblivious of heat. She was walking in the submarine forest of the Island of Crespo, treading on sand "sown with the impalpable dust of shells", when the sudden cracking of a sun-dried branch near at hand startled her and reminded her that time was passing. She closed her book, crept out of her tree, and set off towards the Dell.

"I wish," she said impatiently to herself, "that Time would find something new to do. His one idea seems to be to pass. He may fly or he may crawl, but he is incessantly passing."

She stood still as she spoke and looked before her. Surely the trees were growing more closely together than they had seemed to do; their tall grey-white trunks repeated themselves in a most bewildering way, and right in her path lay a fallen giant which she was perfectly certain she had not passed before.

"Bother! I have come the wrong way," she said, turning round and retracing her steps. "I remember now, there were some trees with rings cut round their trunks—there they are."

She reached the ringed trees, turned her back upon them, and walked straight on. But she came to a dried-up creek which she had not seen before. She could not have missed seeing it, for it was too wide to jump. And there were more ringed trees.
