“Straight down this street,” said the boy, leading the way.  “I am expecting God will show us where to go,” he added.

His companion looked at him in surprise, and Gabriel observed it.  “Don’t you know about God?” he asked.

“Of course.  Who does not?” she returned briefly.

“I did not,” answered Gabriel, “until I found the Book of Life.  It speaks to me in words of flame.  Have you such a book?”

“No.  I will buy it from you,” said the princess.

“No one can do that,” declared the boy, “for it is more precious than all beside.  This morning I looked into it for guidance through the day, and the glowing words were sweet:—­

“’For He shall give his angels charge over thee to keep thee in all thy ways.’”

Gabriel smiled at the princess with such gladness that she gazed at him curiously.

“You cannot refuse to sell me your book,” she said at last, “for I can have your head taken off if I wish.  I am the king’s daughter.”

“God is greater than all kings,” returned Gabriel, “and He would not allow it.  He helped me to get your attention yesterday, and to-day He is sending his angels with us to find Topaz.  The Book of Life is for every one, I believe.  I am sure you can have one, too.”

Here both the boy and girl started, for there came a metallic sound of music on the air.  “Be cautious, be very cautious,” warned Gabriel, and as the princess started to run, he caught her by the arm, a proceeding which horrified the tall man in dark clothes who was at some distance back, but had never taken his eyes from them.  “You must not be too interested,” added the boy, as excited as she.  “A hand-organ is an every-day affair.  We even hear them in the country at times.”

But they both followed the sound, veiling their eagerness as best they might.  When they came in sight of the organ-grinder they both sighed, for he had no assistance from a little dog nor from any one else.

The princess was for turning away impatiently.

“Wait,” said Gabriel, “we are interested in organ music.”  So he persuaded her to stand a minute, while her bright eyes roved in all directions; and the organ man saw a hope of coppers in the pair, for they were decently dressed and lingered in apparent pleasure.  He kept his eyes upon them and at last held out his cap.

The princess had plenty of pence in the bag at her side, placed there by the thoughtful Gabriel in place of the handful of silver with which she had intended to reward street musicians.

“You are one of the common people, your highness; or else you need have no hope of Topaz,” he had reminded her; so now the impatient girl tossed some coppers into the outstretched cap and hurried along as if they were wasting time.

The next organ they found had, sitting upon it, a monkey dressed in red cap and jacket, and Gabriel insisted on waiting to watch him, although the sight of his antics only swelled the princess’s heart as she thought that somewhere Topaz was being forced to such indignity.
