“ And now all days seemed like one day to the Princess, and the next day always seemed the day when her mother would come out of the stone and kiss her again. And the years went slowly by. The wicked King died, and some one else took his kingdom, and many things were changed in the world; but the island did not change, nor the Nine Whirlpools, nor the griffin, nor the dragon, nor the two stone ladies. And all the time, from the very first, the day of the Princess's deliverance was coming, creeping nearer, and nearer, and nearer. ”

“ All good things defend you, Nigel, from sailing near that light. It is not mentioned in all charts; but it is marked in the old chart I steer by, which was my father's father's before me, and his father's father's before him. It is the light that shines from the Lone Tower that stands above the Nine Whirlpools. And when my father's father was young he heard from the very old man, his great-great-grandfather, that in that tower an enchanted Princess, fairer than the day, waits to be delivered. ”

“ And Nigel said he didn't know. Then the witch said: "I'm not a witch anymore. I'm only a happy old woman, but I know some things still. Those whirlpools were made by the enchanter-King's dropping nine drops of his blood into the sea. And his blood was so wicked that the sea has been trying ever since to get rid of it, and that made the whirlpools. Now you've only got to go out at low tide." ”

“ Now, the sum was this: "If the whirlpools stop and the tide goes down once in every twenty-four hours, and they do it five minutes earlier every twenty-four hours, and if the dragon sleeps every day, and he does it three minutes later every day, in how many days and at what time in the day will the tide go down three minutes before the dragon falls asleep?"
It is quite a simple sum, as you see: You could do it in a minute because you have been to a good school and have taken pains with your lessons; but it was quite otherwise with poor Nigel. ”

“ But the snakes knew the Queen was friends with their mistress; so, of course, they had to do their best to be civil.
When the Queen got home, sure enough there was the baby lying in the cradle with the Royal arms blazoned on it, crying as naturally as possible. It had pink ribbons to tie up its sleeves, so the Queen saw at once it was a girl. When the King knew this he tore his black hair with fury.
"Oh, you silly, silly Queen!" he said. "Why didn't I marry a clever lady? Did you think I went to all the trouble and expense of sending you to a witch to get a girl? ”

“ Now there is Something which is wiser than all the world—and it knows when people are worthy to be Princes. And this Something came from the farther side of the seventh world, and whispered in the boy's ear. ”

“ The dragon was clambering down the face of the cliff, and next moment he was crawling and writhing and sprawling and wriggling across the beach after Nigel, making great holes in the sand with his heavy feet—and the very end of his tail, where there were no legs, made, as it dragged, a mark in the sand such as you make when you launch a boat ”
