During the next week, which they spent in journeying towards Vienna, they gave the Sign to three different persons at places which were on the way. In a village across the frontier in Bavaria they found a giant of an old man sitting on a bench under a tree before his mountain "Gasthaus" or inn; and when the four words were uttered, he stood up and bared his head as the guide had done. When Marco gave the Sign in some quiet place to a man who was alone, he noticed that they all did this and said their "God be thanked" devoutly, as if it were part of some religious ceremony. In a small town a few miles away he had to search some hours before he found a stalwart young shoemaker with bright red hair and a horseshoe-shaped scar on his forehead. He was not in his workshop when the boys first passed it, because, as they found out later, he had been climbing a mountain the day before, and had been detained in the descent because his companion had hurt himself.  
When Marco went in and asked him to measure him for a pair of shoes, he was quite friendly and told them all about it.
 
"There are some good fellows who should not climb," he said. "When they find themselves standing on a bit of rock jutting out over emptiness, their heads begin to whirl round—and then, if they don't turn head over heels a few thousand feet, it is because some comrade is near enough to drag them back. There can be no ceremony then and they sometimes get hurt—as my friend did yesterday."
 
"Did you never get hurt yourself?" The Rat asked.
 
"When I was eight years old I did that," said the young shoemaker, touching the scar on his forehead. "But it was not much. My father was a guide and took me with him. He wanted me to begin early. There is nothing like it—climbing. I shall be at it again. This won't do for me. I tried shoemaking because I was in love with a girl who wanted me to stay at home. She married another man. I am glad of it. Once a guide, always a guide." He knelt down to measure Marco's foot, and Marco bent a little forward.
 
"The Lamp is lighted," he said.
 
There was no one in the shop, but the door was open and people were passing in the narrow street; so the shoemaker did not lift his red head. He went on measuring.
 
"God be thanked!" he said, in a low voice. "Do you want these shoes really, or did you only want me to take your measure?"
 
"I cannot wait until they are made," Marco answered. "I must go on."
 
"Yes, you must go on," answered the shoemaker. "But I'll tell you what I'll do—I'll make them and keep them. Some great day might come when I shall show them to people and swagger about them." He glanced round cautiously, and then ended, still bending over his measuring. "They will be called the shoes of the Bearer of the Sign. And I shall say, 'He was only a lad. This was the size of his foot.'" Then he stood up with a great smile.
 
"There'll be climbing enough to be done now," he said, "and I look to see you again somewhere."
 
When the boys went away, they talked it over.
 
"The hair-dresser didn't want to be a hair-dresser, and the shoemaker didn't want to make shoes," said The Rat. "They both wanted to be mountain-climbers. There are mountains in Samavia and mountains on the way to it. You showed them to me on the map.
 
"Yes; and secret messengers who can climb anywhere, and cross dangerous places, and reconnoiter from points no one else can reach, can find out things and give signals other men cannot," said Marco.
 
"That's what I thought out," The Rat answered. "That was what he meant when he said, 'There will be climbing enough to be done now.'"
 
Strange were the places they went to and curiously unlike each other were the people to whom they carried their message. The most singular of all was an old woman who lived in so remote a place that the road which wound round and round the mountain, wound round it for miles and miles. It was not a bad road and it was an amazing one to travel, dragged in a small cart by a mule, when one could be dragged, and clambering slowly with rests between when one could not: the tree-covered precipices one looked down, the tossing whiteness of waterfalls, or the green foaming of rushing streams, and the immensity of farm- and village-scattered plains spreading themselves to the feet of other mountains shutting them in were breath-taking beauties to look down on, as the road mounted and wound round and round and higher and higher.
 
"How can any one live higher than this?" said The Rat as they sat on the thick moss by the wayside after the mule and cart had left them. "Look at the bare crags looming up above there. Let us look at her again. Her picture looked as if she were a hundred years old."
 
Marco took out his hidden sketch. It seemed surely one of the strangest things in the world that a creature as old as this one seemed could reach such a place, or, having reached it, could ever descend to the world again to give aid to any person or thing.
 
Her old face was crossed and recrossed with a thousand wrinkles. Her profile was splendid yet and she had been a beauty in her day. Her eyes were like an eagle's—and not an old eagle's. And she had a long neck which held her old head high.
 
"How could she get here?" exclaimed The Rat.
 
"Those who sent us know, though we don't," said Marco. "Will you sit here and rest while I go on further?"
 
"No!" The Rat answered stubbornly. "I didn't train myself to stay behind. But we shall come to bare-rock climbing soon and then I shall be obliged to stop," and he said the last bitterly. He knew that, if Marco had come alone, he would have ridden in no cart but would have trudged upward and onward sturdily to the end of his journey.
 
But they did not reach the crags, as they had thought must be inevitable. Suddenly half-way to the sky, as it seemed, they came to a bend in the road and found themselves mounting into a new green world—an astonishing marvel of a world, with green velvet slopes and soft meadows and thick woodland, and cows feeding in velvet pastures, and—as if it had been snowed down from the huge bare mountain crags which still soared above into heaven—a mysterious, ancient, huddled village which, being thus snowed down, might have caught among the rocks and rested there through all time.
 
There it stood. There it huddled itself. And the monsters in the blue above it themselves looked down upon it as if it were an incredible thing—this ancient, steep-roofed, hanging-balconied, crumbling cluster of human nests, which seemed a thousand miles from the world. Marco and The Rat stood and stared at it. Then they sat down and stared at it.
 
"How did it get here?" The Rat cried.
 
Marco shook his head. He certainly could see no explanation of its being there. Perhaps some of the oldest villagers could tell stories of how its first chalets had gathered themselves together.
 
An old peasant driving a cow came down a steep path. He looked with a dull curiosity at The Rat and his crutches; but when Marco advanced and spoke to him in German, he did not seem to understand, but shook his head saying something in a sort of dialect Marco did not know.
 
"If they all speak like that, we shall have to make signs when we want to ask anything," The Rat said. "What will she speak?"
 
"She will know the German for the Sign or we should not have been sent here," answered Marco. "Come on."
 
They made their way to the village, which huddled itself together evidently with the object of keeping itself warm when through the winter months the snows strove to bury it and the winds roared down from the huge mountain crags and tried to tear it from among its rocks. The doors and windows were few and small, and glimpses of the inside of the houses showed earthen floors and dark rooms. It was plain that it was counted a more comfortable thing to live without light than to let in the cold.
 
It was easy enough to reconnoiter. The few people they saw were evidently not surprised that strangers who discovered their unexpected existence should be curious and want to look at them and their houses.
 
The boys wandered about as if they were casual explorers, who having reached the place by chance were interested in all they saw. They went into the little Gasthaus and got some black bread and sausage and some milk. The mountaineer owner was a brawny fellow who understood some German. He told them that few strangers knew of the village but that bold hunters and climbers came for sport. In the forests on the mountain sides were bears and, in the high places, chamois. Now and again, some great gentlemen came with parties of the daring kind—very great gentlemen indeed, he said, shaking his head with pride. There was one who had castles in other mountains, but he liked best to come here. Marco began to wonder if several strange things might not be true if great gentlemen sometimes climbed to the mysterious place. But he had not been sent to give the Sign to a great gentleman. He had been sent to give it to an old woman with eyes like an eagle which was young.
 
He had a sketch in his sleeve, with that of her face, of her steep-roofed, black-beamed, balconied house. If they walked about a little, they would be sure to come upon it in this tiny place. Then he could go in and ask her for a drink of water.
 
They roamed about for an hour after they left the Gasthaus. They went into the little church and looked at the graveyard and wondered if it was not buried out of all sight in the winter. After they had done this, they sauntered out and walked through the huddled clusters of houses, examining each one as they drew near it and passed.
 
"I see it!" The Rat exclaimed at last. "It is that very old-looking one standing a little way from the rest. It is not as tumbled down as most of them. And there are some red flowers on the balcony."
 
"Yes! That's it!" said Marco.
 
They walked up to the low black door and, as he stopped on the threshold, Marco took off his cap. He did this because, sitting in the doorway on a low wooden chair, the old, old woman with the eagle eyes was sitting knitting.
 
There was no one else in the room and no one anywhere within sight. When the old, old woman looked up at him with her young eagle's eyes, holding her head high on her long neck, Marco knew he need not ask for water or for anything else.
 
"The Lamp is lighted," he said, in his low but strong and clear young voice.
 
She dropped her knitting upon her knees and gazed at him a moment in silence. She knew German it was clear, for it was in German she answered him.
 
"God be thanked!" she said. "Come in, young Bearer of the Sign, and bring your friend in with you. I live alone and not a soul is within hearing."
 
She was a wonderful old woman. Neither Marco nor The Rat would live long enough to forget the hours they spent in her strange dark house. She kept them and made them spend the night with her.
 
"It is quite safe," she said. "I live alone since my man fell into the crevasse and was killed because his rope broke when he was trying to save his comrade. So I have two rooms to spare and sometimes climbers are glad to sleep in them. Mine is a good warm house and I am well known in the village. You are very young," she added shaking her head. "You are very young. You must have good blood in your veins to be trusted with this."
 
"I have my father's blood," answered Marco.
 
"You are like some one I once saw," the old woman said, and her eagle eyes set themselves hard upon him. "Tell me your name."
 
There was no reason why he should not tell it to her.
 
"It is Marco Loristan," he said.
 
"What! It is that!" she cried out, not loud but low.
