The streets and walks were as clean as a parlor floor, and no obstructions were to be seen upon them. The pavement was of a soft gray tint, and like a felt blanket in its appearance. The sidewalks were laid in tessellated work of all the hues of the solar spectrum. Statues and works of art were everywhere observable. Great trees ranged on either side, while beautiful plants and green grass plats surrounded many of the buildings. As the rays of the sun in the west fell upon the buildings, they were reflected back to the opposite side of the street, again and again reflected, and the eye of Cobb beheld the parallel lines of Pennsylvania Avenue adorned with millions of sparkling, dancing lights, meeting at the farther end in one great diamond whose lustre could almost compare with the sun itself. Ah! what a grand sight!--worthy of a life of inanimation for a thousand years. Cobb feasted his eyes on the beauty of the scene. Lost in the ecstasy of the moment, he was rudely awakened to a sense of the reality by the President remarking: "It is a grand sight, is it not?" "Yes! yes, indeed! Grand beyond expression!" "This street, Colonel Cobb, is said to be the handsomest in the world." "I can well believe it! I cannot conceive of one that could be more beautiful." "And yet, Colonel, it is all glass." "Glass?"

I find I must accept as possible every theory and proposition advanced, until it is, by undeniable evidence, totally disproved. But blame me not if doubt sometimes arises. Will you stop the drag a moment?" "Certainly," was the puzzled answer. Turning his head to the driver in the rear, he ordered the drag stopped at the curb. In front of the entrance to the Dom Kanitöl Legletik (Grand Opera House), by the side of two tall and elaborately carved pillars covered with fine and thread-like filigree work, the drag came to a standstill. Without a word of explanation, Cobb sprang from his seat, walked up to the nearest pillar and dashed the heel of his boot against a beautiful rose of pure white. A look of triumph came into his eyes. They might make it to appear like glass, but it was not glass! The beautiful rose lay crushed against its stem, its delicate petals bent and twisted, and its leaves flattened together. The President comprehended the young man's motive, and smiled. As Cobb again entered the drag, the President said, but kindly:
