The two ghosts with dead white faces stood peering. Then the man moved
forward. His dead, strange voice called:

"Drop that paper!"

My Lord Howe's red-coated officers dropped the parchment and fled.

And later, when Atwood's body was taken away to be given burial as
befitted an enemy officer and a gentleman, that missive from Mary
Atwood had disappeared. It was never found.

Tony Green and his fellows said nothing of this latter incident. One
cannot with grace explain being routed by a ghost. Not an officer of
His Majesty's army!

Unrecorded history! A supernatural incident of the year 1777!

Undoubtedly in the past ages there have been many such affairs: some
never recorded, others interwoven in written history and called
supernatural.

Yet why must they be that? There was nothing supernatural in the
events of that night in Major Atwood's garden.

Is this perchance an explanation of why the pages of history are so
thronged with tales of ghosts? There must, indeed, be many future ages
down the corridors of Time where the genius of man will invent devices
to fling him back into his past. And the impressions upon the past
which he makes are called supernatural.

Whether this be so or not, it was so in the case of these two
Time-traveling vehicles from 2930. Larry and I think that the world of
1935 is just now shaking off the shackles of superstition, and coming
to realize that what is called the supernatural is only the Unknown.
Who can say, up to 1935, how many Time-traveling humans have come
briefly back? Is this, perchance, what we call the phenomena of the
supernatural?

Larry and Tina--anything but ghosts, very much alive and very much
perturbed--were standing back of that tree. They saw the British
officers reading the scrap of paper. They could hear only the words,
"Mary," and "from Mistress Atwood."

"A message!" Larry whispered. "She and George must have found a chance
to write it, and dropped it here while the Robot murdered Major
Atwood!"

Larry and Tina vehemently wanted to read the note. Tina whispered:

"If we show ourselves, they will be frightened and run. It is nearly
always so where Harl and I have become visible in earlier Times."

"Yes. I'll try it."

Larry stepped from the tree, and shouted, "Drop that paper!"

And a moment later, with Mary's torn little note scribbled on a scrap
of
