"Don't know," said Chubbins, honestly. "It's been years and years since this door was opened. You can see for yourself. That rock must have covered it up a long time."

"There must be _something_ inside," she declared, "or there wouldn't be any door, or any steps."

"That's so," answered Chubbins. "I'll go down and see. You wait."

"No; I'll go too," said Twinkle. "I'd be just as scared waiting outside as I would be in. And I 'in bigger than you are, Chub."

"You're taller, but you're only a month older, Twink; so don't you put on airs. And I'm the strongest."

"We'll both go," she decided; "and then if we find the treasure we'll divide."

"All right; come on!"

Forgetting their basket, which they left upon the rocks, they crept through the little doorway and down the steps. There were only seven steps in all, and then came a narrow but level tunnel that led straight into the mountain-side. It was dark a few feet from the door, but the children resolved to go on. Taking hold of hands, so as not to get separated, and feeling the sides of the pa.s.sage to guide them, they walked a long way into the black tunnel.

Twinkle was just about to say they'd better go back, when the pa.s.sage suddenly turned, and far ahead of them shone a faint light. This encouraged them, and they went on faster, hoping they would soon come to the treasure.

"Keep it up, Twink," said the boy. "It's no use going home yet."

"We must be almost in the middle of Sugar-Loaf Mountain," she answered.

"Oh, no; it's an awful big mountain," said he. "But we've come quite a way, haven't we?"

"I guess mama'd scold, if she knew where we are."

"Mamas," said Chubbins, "shouldn't know everything, 'cause they'd only worry. And if we don't get hurt I can't see as there's any harm done."

"But we mustn't be naughty, Chub."

"The only thing that's naughty," he replied, "is doing what you're told not to do. And no one told us not to go into the middle of Sugar-Loaf Mountain."

Just then they came to another curve in their path, and saw a bright light ahead. It looked to the children just like daylight; so they ran along and soon pa.s.sed through a low arch and came out into--

Well! the scene before them was so strange that it nearly took away their breath, and they stood perfectly still and stared as hard as their big eyes could possibly stare.

Chapter III Sugaf-Loaf City

SUGAR-LOAF Mountain was hollow inside, for the children stood facing a great dome that rose so far above their heads that it seemed almost as high as the sky. And underneath this dome lay spread out the loveliest city imaginable. There were streets of houses, and buildings with round domes, and slender, delicate spires reaching far up into the air, and turrets beautifully ornamented with carvings. And all these were white as the driven snow and sparkling in every part like millions of diamonds--for all were built of pure loaf-sugar! The pavements of the streets were also loaf-sugar, and the trees and bushes and flowers were likewise sugar; but these last were not all white, because all sugar is not white, and they showed many bright colors of red sugar and blue sugar and yellow, purple and green sugar, all contrasting most prettily with the sparkling white buildings and the great white dome overhead.

This alone might well astonish the eyes of children from the outside world, but it was by no means all that Twinkle and Chubbins beheld in that first curious look at Sugar-Loaf City. For the city was inhabited by many people--men, women and children--who walked along the streets just as briskly as we do; only all were made of sugar. There were several different kinds of these sugar people. Some, who strutted proudly along, were evidently of pure loaf-sugar, and these were of a most respectable appearance. Others seemed to be made of a light brown sugar, and were more humble in their manners and seemed to hurry along as if they had business to attend to. Then there were some of sugar so dark in color that Twinkle suspected it was maple-sugar, and these folks seemed of less account than any of the others, being servants, drivers of carriages, and beggars and idlers.

Carts and carriages moved along the streets, and were mostly made of brown sugar. The horses that drew them were either pressed sugar or maple-sugar. In fact, everything that existed in this wonderful city was made of some kind of sugar.

Where the light, which made all this place so bright and beautiful, came from, Twinkle could not imagine. There was no sun, nor were there any electric lights that could be seen; but it was fully as bright as day and everything showed with great plainness.

While the children, who stood just inside the archway through which they had entered, were looking at the wonders of Sugar-Loaf City, a file of sugar soldiers suddenly came around a corner at a swift trot.

"Halt!" cried the Captain. He wore a red sugar jacket and a red sugar cap, and the soldiers were dressed in the same manner as their Captain, but without the officer's yellow sugar shoulder-straps. At the command, the sugar soldiers came to a stop, and all pointed their sugar muskets at Twinkle and Chubbins.

"Surrender!" said the Captain to them. "Surrender, or I'll--I'll--"

He hesitated.

"What will you do?" said Twinkle.

"I don't know what, but something very dreadful," replied the Captain.

"But of course you'll surrender."

"I suppose we'll have to," answered the girl.

"That's right. I'll just take you to the king, and let him decide what to do," he added pleasantly.

So the soldiers surrounded the two children, shouldered arms, and marched away down the street, Twinkle and Chubbins walking slowly, so the candy folks would not have to run; for the tallest soldiers were only as high as their shoulders.

"This is a great event," remarked the Captain, as he walked beside them with as much dignity as he could muster. "It was really good of you to come and be arrested, for I haven't had any excitement in a long time.

The people here are such good sugar that they seldom do anything wrong."

Chapter IV To the King's Palace

"WHAT, allow me to ask, is your grade of sugar?" inquired the Captain, with much politeness. "You do not seem to be the best loaf, but I suppose that of course you are solid."

"Solid what?" asked Chubbins.

"Solid sugar," replied the Captain.

"We're not sugar at all," explained Twinkle. "We're just meat."

"Meat! And what is that?"

"Haven't you any meat in your city?"

"No," he replied, shaking his head. "Well, I can't explain exactly what meat is," she said; "but it isn't sugar, anyway."

At this the Captain looked solemn.

"It isn't any of my business, after all," he told them. "The king must decide about you, for that's _his_ business. But since you are not made of sugar you must excuse me if I decline to converse with you any longer. It is beneath my dignity."

"Oh, that's all right," said Twinkle.

"Where we came from," said Chubbins, "meat costs more a pound than sugar does; so I guess we're just as good as you are."

But the Captain made no reply to this statement, and before long they stopped in front of a big sugar building, while a crowd of sugar people quickly gathered.

"Stand back!" cried the Captain, and the sugar soldiers formed a row between the children and the sugar citizens, and kept the crowd from getting too near. Then the Captain led Twinkle and Chubbins through a high sugar gateway and up a broad sugar walk to the entrance of the building.
