"Do you still see chat palm tree?"
"I chink so."
They moved across the sand in silence. After a few min-
utes it seemed firmer under their feet, and they saw that
there was rock under the sand.
"That's better," Sandy said.
"Hey!"
The ground seemed to shudder under their feet. Dennys
flailed his arms to try to keep his balance, but was flung to
the ground. "Is this an earthquake or something?"
Sandy, too, was thrown down. Around them they could
hear a noisy grating of rock, and a deep, thunderous roar-
ing beneath them. Then there was silence, abrupt and
complete. The rock steadied under them. The earthquake,
or whatever it was, had lasted less than a minute, but it had
been of sufficient force to push up a large section of rock,
making a small cliff about six feet high. It was striated
and raw-looking, but it provided a shadow that stretched
across the sand.
Both boys climbed to their feet and headed into the

welcome shade. Sandy touched the sheared-off rock, and
it felt cool. "Maybe we could sit here for a minute . . ."
The sun was still fiercely hot. but the slab of rock they
sat on was cool. The relief of the shade was so great that

shade.
"I don't know what's going to happen next, but what-
ever it is, I'm not likely to be surprised," Sandy said at
last. "Are you sure it was Dad's experiment we weren't
supposed to interrupt? Couldn't it have been Mother's?"
"Mother's doing something with sub-atomic particles
again," Dennys said. "Last night at dinner, she spent most
of the time talking about virtual particles."
"It sounded crazy to me," Sandy said. "Particles which
have a tendency to life."
"That's right." Dennys nodded- "Virtual particles. Al-
most-particles. What you said. Particles which tend to be."
Sandy shook his head. "Most of Mother's sub-atomic
experiments are so, oh, so sort of infinitesimal, it hasn't
mattered if we've come into the lab."
"But maybe if she's looking for a virtual particle—"
Dennys sounded hopeful.
"No. It sounds to me more like something of Dad's. It
