at they should first
go above. They came to the place where they could look out into the main
floor. They were near the great clock tower just as the chimes began to
peal forth their weird melodies.

"What's that?" cried Aunt, in awe-struck tones.

"It's the chime of the bells," cried Fanny, in delight, "listen!
listen!"

Clear and plain through the vast building and to the streets on the
outside came the slow measured notes of that nation-thrilling air, "My
Country, 'tis of Thee."

All stood entranced before a scene never before reached by human means.
When the chimes were done, Uncle said: "Let us go down to the main
floor. I want to walk from end to tother of that aisle."

Johnny held in each hand a camp-stool for Uncle and Aunt, and he
arranged the stools for them to sit awhile before that wonderful scene.
Not long after, they were marching down that aisle called Columbia
avenue. They felt themselves every inch as citizens of a great republic.
It is not a very long thoroughfare--only a third of a mile--but they
were two hours on the way. Uncle was a common, everyday American citizen
when he started. At each step it seemed to him he swelled in his own
estimation. At the clock tower he was proud enough to ascend that
structure and make a Fourth of July speech. At the end of his walk he
wanted to wear an eagle on his hat and shout till his throat should be
stiff. It was not solely as an American that he was filled with
exultation but as a member of the human race. He was lifted up with
pride in the achievements of his fellow-man and in satisfaction that his
own country was the host of such a splendid company.

Columbia avenue is the broad thoroughfare which traverses the center of
the greatest building that ever was. It runs through the Manufactures
and Liberal Arts building from the grand court to the plaza at the
northern end. A walk down this thoroughfare is like a tour of the world
in sixty minutes. Though, if you are to do it in sixty minutes, you must
fifty times repress an impulse to linger beside some new marvel in the
handiwork of man and go marching on. You cannot beat the record in a
trip around the world and stop and see all the grand cathedrals and
picturesque ruins and beautiful women and inviting galleries of art.

Columbia avenue is a picture never to be surpassed. It is a cleanly and
an attractive thoroughfare for the world of tourists who throng the way.
The path is no longer littered with lum
