The doctor takes me around to the place he boards at, and shows me a
nigger waiter he has been experimenting on. He had paid the nigger's
fine in a police court fur slashing another nigger some with a knife,
and kept him from going into the chain-gang. So the nigger agreed he
could use his hide to try different kinds of medicines on. He was a
velvety-looking, chocolate-coloured kind of nigger to start with, and
the best Doctor Kirby had been able to do so fur was to make a few
little liver-coloured spots come onto him. But it was making the nigger
sick, and the doctor was afraid to go too fur with it, fur Sam might die
and we would be at the expense of another nigger. Peroxide of hidergin
hadn't even phased him. Nor a lot of other things we tried onto him.

You never seen a nigger with his colour running into him so deep as
Sam's did. Sam, he was always apologizing about it, too. You could see
it made him feel real bad to think his colour was so stubborn. He felt
like it wasn't being polite to the doctor and me, Sam did, fur his skin
to act that-a-way. He was a willing nigger, Sam was. The doctor, he says
he will find out the right stuff if he has to start at the letter A and
work Sam through every drug in the hull blame alphabet down to Z.

Which he finally struck it. I don't exactly know what she had in her,
but she was a mixture of some kind. The only trouble with her was she
didn't work equal and even--left Sam's face looking peeled and spotty in
places. But still, in them spots, Sam was six shades lighter.
The doctor says that is jest what he wants, that there
passing on-to-the-next-cage-we-have-the-spotted-girocutus-look, as he
calls it. The chocolate brown and the lighter spots side by side, he
says, made a regular Before and After out of Sam's face, and was the
best advertisement you could have.

Then we goes and has a talk with Doctor Jackson himself. Doctor Kirby
has the idea mebby he will put some money into it. Doctor Jackson was
setting on his front veranda with his chair tilted back, and his feet,
with red carpet slippers on 'em, was on the railing, and he was smoking
one of these long black cigars that comes each one in a little glass
tube all by itself. He looks Sam over very thoughtful, and he says:

"Yes, it will do the work well enough. I can see that. But will it
sell?"

Doctor Kirby makes him quite a speech. I never hearn him make a better
one. Doctor Jackson he listens very calm, wi
