"HIS HALF-DOLLAR ENTRANCE FEE GAVE HIM THE RIGHT TO SEE THE DOME FROM THE MOST ADVANTAGEOUS POSITION."

But one of the Columbian guards seemed to think that was not the legal way to view the dizzy heights of the building and forthwith jerked him to his feet and ushered him to the outside. The last seen of the man he was muttering, "Them fool builders put them picters clear up at the top and then the fool guards wont let a fellow enjoy them."

He evidently believed he had been treated outrageously in a free country by an autocratic guard, and that his fifty cents entrance fee entitled him to view any object in any position of vantage.

They went on into the Mines building where the sparkling ores of a thousand mines were in piles and pyramids or wrought into colonnades, facades and burnished domes. There were dazzling diamonds and beautiful opals, emeralds and gems from all parts of the earth; Michigan's copper globe, North Carolina's pavilion of mica designs, Montana's famous Rehan statue of solid silver resting on a plinth of gold, Arizona's old Spanish arastra and New Mexico's mining cabin.

From a northwest doorway they passed on out of this world of subterranean wonders across the street into the Transportation building.

"I don't believe these things are used anywhere," said Johnny. "They're like the four-legged woman—just made for show. Father, you can't expect me to ride in no common farm wagon after bringin' me to see this."

"These cars do represent awful improvement in three generations," said Uncle. "Now, it is supposed that when I was a boy I rode in that 'Flyer' there, or on the one they call 'Rocket;' but I didn't, 'cause I never seed a train till I was past twenty. Fanny would be supposed to ride up there in that gay three-story palace on wheels, and Johnny will get to ride a hundred and fifty miles an hour on that 'lectric railroad; but a common cattle car is fast enough for me. I don't know what the world's a comin' to when people rides a hundred and fifty miles an hour and choose to sleep fourteen stories high."

They had wandered around the locomotive section, and on their way curiously viewed the famous "John Bull," the oldest locomotive in America. Near by some workingmen throwing a pile of dirt into a cart, caught Uncle's eye.
