the stars and tracked them in their orbits. The boy had found out the
mechanism of a windmill; the man explained to his fellow-men the
mechanism of the universe.

While making these researches he was accustomed to spend night after
night in a lofty tower, gazing at the heavenly bodies through a
telescope. His mind was lifted far above the things of this world.
He may be said, indeed, to have spent the greater part of his life in
worlds that lie thousands and millions of miles away; for where the
thoughts and the heart are, there is our true existence.

Did you never hear the story of Newton and his little dog Diamond?
One day, when he was fifty years old, and had been hard at work more
than twenty years studying the theory of light, he went out of his
chamber, leaving his little dog asleep before the fire. On the table
lay a heap of manuscript papers, containing all the discoveries which
Newton had made during those twenty years. When his master was gone, up
rose little Diamond, jumped upon the table, and overthrew the lighted
candle. The papers immediately caught fire.

Just as the destruction was completed Newton opened the chamber door,
and perceived that the labors of twenty years were reduced to a heap of
ashes. There stood little Diamond, the author of all the mischief.
Almost any other man would have sentenced the dog to immediate death.
But Newton patted him on the head with his usual kindness, although
grief was at his heart.

"O Diamond, Diamond," exclaimed he, "thou little knowest the mischief
then hast done!"
