Marco did not wait for The Rat to recover his breath and speak.

“I know why he looks at you so,” he answered for him.  “He is startled.  Yesterday we went to a hair-dresser’s shop down below there, and we saw a man who was almost exactly like you—­only—­” he added, looking up, “his eyes were gray and yours are brown.”

“He was my twin brother,” said the guide, puffing at his pipe cheerfully.  “My father thought he could make hair-dressers of us both, and I tried it for four years.  But I always wanted to be climbing the mountains and there were not holidays enough.  So I cut my hair, and washed the pomade out of it, and broke away.  I don’t look like a hair-dresser now, do I?”

He did not.  Not at all.  But Marco knew him.  He was the man.  There was no one on the mountain-top but themselves, and the sun was just showing a rim of gold above the farthest and highest giant’s shoulders.  One need not be afraid to do anything, since there was no one to see or hear.  Marco slipped the sketch out of the slit in his sleeve.  He looked at it and he looked at the guide, and then he showed it to him.

“That is not your brother.  It is you!” he said.

The man’s face changed a little—­more than any other face had changed when its owner had been spoken to.  On a mountain-top as the sun rises one is not afraid.

“The Lamp is lighted,” said Marco.  “The Lamp is lighted.”

“God be thanked!” burst forth the man.  And he took off his hat and bared his head.  Then the rim behind the mountain’s shoulder leaped forth into a golden torrent of splendor.

And The Rat stood up, resting his weight on his crutches in utter silence, and stared and stared.

“That is three!” said Marco.

THE SILVER HORN

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.
