I don't suppose you caught any glimpse of me in
your plate?" asked Tom, half hopefully.
"No. I couldn't see a thing. So you are going to try and make this
thing work both ways, are you?"
"That's my intention, But I can fix it so that a person can
control the apparatus at his end, and only see the person he is
talking to, not being seen himself, unless he wishes it. That is,
I hope to do that. Just now nobody can see anybody," and Tom
sighed.
"Give it up," advised Ned. "It's too hard a nut to crack, Tom!"
"Indeed, I'll not give it up, Ned! I'm going to work along a new
line. I must try a different solution of selenium on the metal
plate. Perhaps I may have to try using a sensitized plate, and
develop it later, though I do want to get the machine down so you
can see a perfect image without the need of developing. And I
will, too!" cried Tom. "I'll get some new selenium."
Eradicate, who came into the shop just then, heard the end of
Tom's remarks. A strange look came over his honest black face, and
he exclaimed:

heah? Dat's de end of de world, ain't it-dat millenium? Golly!
Dish yeah coon neber 'spected t' lib t' see dat. De millenium! Oh
mah landy!"
"No, Rad!" laughed Tom. "I was speaking about selenium, a sort of
metallic combination that is a peculiar conductor of electricity.
