and he was a small boy at the
seashore again, entranced with his first shell discovery. He could even
hear his mother's voice calling "Be careful, Martin! Don't go too far!"

He walked on and on, slowly, uncertainly, until the beach and the sea
began to waver like a heat mirage. And suddenly the shells and the water
vanished and he was on the green grass again with the grove of trees
just ahead. He turned, saw a white highway with his car parked on the
shoulder.

Dazedly, Sutter walked back to the car....

All next morning he ruminated over his strange experience. Toward noon
the pieces of the puzzle began to fit slowly together in his mind. But
the partial answer at which he arrived seemed too fantastic for belief.
Could it be possible that when he had stopped at the roadside stand he
had blundered, in some inexplicable way, into another dimension?

Sutter had a layman's knowledge of Einsteinian physics, and he knew that
experiments in Time were being made every day. Only last week he had
read in the paper of an army officer who had reportedly Time-traveled
some twenty-two minutes. And a year ago the Belgian scientist, Delgar,
claimed to have entered a secondary world which he declared impinged on
our own.

Assuming all this to be true, then it could be that the Tanganyika
television set was a product manufactured in Future Time by a company
that, by Sutter's Time standards, didn't yet exist.

The following day saw Sutter begin an experiment of which he was rather
proud. Travail had said that he had tried to tune in the noon news
broadcast yesterday on the TV and had turned the set on from twelve
o'clock until five minutes after. At a nearby appliance store Sutter
purchased a clock control which would turn his television set on and off
at any chosen time. He set the control for two o'clock, then managed to
lure Travail out of the house for the afternoon by giving him an
invitation he'd received for a lecture on marine life at a local club.
Next, he drove again to the H-bomb site and stood waiting in the
grass-like park, watch in hand.

At precisely two o'clock there came that queer staggering of earth and
sky. The trees gave way to the stretch of sand; the waves,
leaden-colored and cheerless, dotted with white caps rolled up on the
lonely shore. As before Sutter felt that same exhilaration, that same
reversal to the spirit of his youth. But despite his mental excitement
he maintained an awareness of the situat
