ing 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:
"What all am dat, Massa Tom? Yo'ah gwine t' bring de new millennium heah? Dat's de end of de world, ain't it—dat millennium? Golly! Dish yeah coon never 'spected t' lib t' see dat. De millennium! Oh mah landy!"
