“You must do without me, as most people have to do, for nine hundred and ninety-nine thousandths of their lives; and look at the dog instead; for he knows the way well enough, and will not forget it.  Besides, you may meet some very queer-tempered people there, who will not let you pass without this passport of mine, which you must hang round your neck and take care of; and, of course, as the dog will always go behind you, you must go the whole way backward.”

“Backward!” cried Tom.  “Then I shall not be able to see my way.”

“On the contrary, if you look forward, you will not see a step before you, and be certain to go wrong; but if you look behind you, and watch carefully whatever you have passed, and especially keep your eye on the dog, who goes by instinct, and therefore can’t go wrong, then you will know what is coming next, as plainly as if you saw it in a looking-glass.”

Tom was very much astonished; but he obeyed her, for he had learnt always to believe what the fairies told him.

Tom was very sorely tried; for though, by keeping the dog to heels (or rather to toes, for he had to walk backward), he could see pretty well which way the dog was hunting, yet it was much slower work to go backwards than to go forwards.

But I am proud to say that, though Tom had not been to Cambridge—­for if he had he would have certainly been senior wrangler—­he was such a little dogged, hard, gnarly, foursquare brick of an English boy, that he never turned his head round once all the way from Peacepool to the Other-end-of-Nowhere; but kept his eye on the dog, and let him pick out the scent, hot or cold, straight or crooked, wet or dry, up hill or down dale; by which means he never made a mistake, or had to retrace a single step.

CHAPTER VIII AND LAST

Now, as soon as Tom had left Peacepool, he came to the white lap of the great sea mother, ten thousand fathoms deep; where she makes world-pap all day long, for the steam giants to knead, and the fire giants to bake, till it has risen and hardened into mountain-loaves and island-cakes.

And there Tom was very near being kneaded up in the world-pap, and turned into a fossil water baby; which would have astonished the Geological Society of New Zealand some hundreds of thousands of years hence.

For as he walked along in the silence of the sea twilight, on the soft white ocean floor, he was aware of a hissing, and a roaring, and a thumping, and a pumping, as of all the steam engines in the world at once.  And when he came near, the water grew boiling hot; not that that hurt him in the least; but it also grew as foul as gruel; and every moment he stumbled over dead shells, and fish, and sharks, and seals, and whales, which had been killed by the hot water.

And at last he came to the great sea serpent himself, lying dead at the bottom; and as he was too thick to scramble over, Tom had to walk round him three quarters of a mile and more, which put him out of his path sadly; and when he had got round, he came to the place called Stop.  And there he stopped, and just in time.
