against stopping; it was indescribable, but he was aware of it. He had
lived these years once, and they were forbidden to him again.

The cage was still in its starting acceleration. They swept through
the year 1935, and then Larry was indefinably aware that the forbidden
area had passed.

They went through those few days of June, 1935, during which Tugh's
Robots had devastated the city, but it was too brief an action to make
a mark that Larry could see. It left a few very transitory marks,
however. Larry noticed that along the uneven line of ghostly
roof-tops, blobs of emptiness had appeared; he saw a short distance
away that several of the houses had melted down into ragged, tumbled
heaps. These were where the bombs had struck, dropped by the
Government planes in an endeavor to wreck the Tugh house from which
the Robots were appearing. But the ragged, broken areas were filled in
a second--almost as soon as Larry realized they were there--and new
and larger buildings than before appeared.

At sight of all this he murmured to Tina, "Something has happened
here. I wonder what?"

He chanced to turn, and saw that Tugh was regarding him very queerly;
but in a moment he forgot it in the wonders of the passage into his
future.

This growing, expanding city! It had seemed a giant to Larry in 1935,
especially after he had compared it to what it was in 1777. But now,
in 1950, and beyond to the turn of the century, he stood amazed at the
enormity of the shadowy structures rearing their spectral towers
around him. For some years Patton Place, a backward section, held its
general form; then abruptly the city engulfed it. Larry saw monstrous
buildings of steel and masonry rising a thousand feet above him. For
an instant, as they were being built he saw their skeleton outlines;
and then they were complete. Yet they were not enduring, for in every
flowing detail they kept changing.

An overhead sidewalk went like a balcony along what had been Patton
Place. Bridges and archways spanned the street. Then there came a
triple bank of overhead roadways. A distance away, a hundred feet
above the ground level, the shadowy form of what seemed a monorail
structure showed for a moment. It endured for what might have been a
hundred years, and then it was gone....
