Then they went on again, till they began to see the peak of Jan Mayen's Land, standing-up like a white sugar-loaf, two miles above the clouds.
And there they fell in with a whole flock of molly-mocks, who were feeding on a dead whale.
"These are the fellows to show you the way," said Mother Carey's chickens; "we cannot help you farther north. We don't like to get among the ice pack, for fear it should nip our toes: but the mollys dare fly anywhere."
So the petrels called to the mollys: but they were so busy and greedy, gobbling and peeking and spluttering and fighting over the blubber, that they did not take the least notice.
"Come, come," said the petrels, "you lazy greedy lubbers, this young gentleman is going to Mother Carey, and if you don't attend on him, you won't earn your discharge from her, you know."
"Greedy we are," says a great fat old molly, "but lazy we ain't; and, as for lubbers, we're no more lubbers than you. Let's have a look at the lad."
And he flapped right into Tom's face, and stared at him in the most impudent way (for the mollys are audacious fellows, as all whalers know), and then asked him where he hailed from, and what land he sighted last.
And, when Tom told him, he seemed pleased, and said he was a good plucked one to have got so far.
"Come along, lads," he said to the rest, "and give this little chap a cast over the pack, for Mother Carey's sake. We've eaten blubber enough for to-day, and we'll e'en work out a bit of our time by helping the lad."
So the mollys took Tom up on their backs, and flew off with him, laughing and joking - and oh, how they did smell of train oil!
"Who are you, you jolly birds?" asked Tom.
"We are the spirits of the old Greenland skippers (as every sailor knows), who hunted here, right whales and horse-whales, full hundreds of years agone. But, because we were saucy and greedy, we were all turned into mollys, to eat whale's blubber all our days.
But lubbers we are none, and could sail a ship now against any man in the North seas, though we don't hold with this new-fangled steam. And it's a shame of those black imps of petrels to call us so; but because they're her grace's pets, they think they may say anything they like."
"And who are you?" asked Tom of him, for he saw that he was the king of all the birds.
"My name is Hendrick Hudson, and a right good skipper was I; and my name will last to the world's end, in spite of all the wrong I did.
For I discovered Hudson River, and I named Hudson's Bay; and many have come in my wake that dared not have shown me the way. But I was a hard man in my time, that's truth, and stole the poor Indians off the coast of Maine, and sold them for slaves down in Virginia; and at last I was so cruel to my sailors, here in these very seas, that they set me adrift in an open boat, and I never was heard of more. So now I'm the king of all mollys, till I've worked out my time."
And now they came to the edge of the pack, and beyond it they could see Shiny Wall looming, through mist, and snow, and storm. But the pack rolled horribly upon the swell, and the ice giants fought and roared, and leapt upon each other's backs, and ground each other to powder, so that Tom was afraid to venture among them, lest he should be ground to powder too. And he was the more afraid, when he saw lying among the ice pack the wrecks of many a gallant ship; some with masts and yards all standing, some with the seamen frozen fast on board. Alas, alas, for them! They were all true English hearts; and they came to their end like good knights-errant, in searching for the white gate that never was opened yet.
But the good mollys took Tom and his dog up, and flew with them safe over the pack and the roaring ice giants, and set them down at the foot of Shiny Wall.
"And where is the gate?" asked Tom.
"There is no gate," said the mollys.
"No gate?" cried Tom, aghast.
"None; never a crack of one, and that's the whole of the secret, as better fellows, lad, than you have found to their cost; and if there had been, they'd have killed by now every right whale that swims the sea."
"What am I to do, then?"
"Dive under the floe, to be sure, if you have pluck."
"I've not come so far to turn now," said Tom; "so here goes for a header."
"A lucky voyage to you, lad," said the mollys; "we knew you were one of the right sort. So good-bye."
"Why don't you come too?" asked Tom.
But the mollys only wailed sadly, "We can't go yet, we can't go yet," and flew away over the pack.
So Tom dived under the great white gate which never was opened yet, and went on in black darkness, at the bottom of the sea, for seven days and seven nights. And yet he was not a bit frightened. Why should he be? He was a brave English lad, whose business is to go out and see all the world.
And at last he saw the light, and clear clear water overhead; and up he came a thousand fathoms, among clouds of sea-moths, which fluttered round his head. There were moths with pink heads and wings and opal bodies, that flapped about slowly; moths with brown wings that flapped about quickly; yellow shrimps that hopped and skipped most quickly of all; and jellies of all the colours in the world, that neither hopped nor skipped, but only dawdled and yawned, and would not get out of his way. The dog snapped at them till his jaws were tired; but Tom hardly minded them at all, he was so eager to get to the top of the water, and see the pool where the good whales go.
