They say they can make the furniture move of itself. If it does move
they move it; and we mean to know how.

[_A chair falls over with a slight crash._

[MORRIS _almost staggers and momentarily fights for breath and
words._

MORRIS. You ... why ... that ... every one knows that ... a sliding
plank. It can be done with a sliding plank.

CONJURER. [_Without looking up._] Yes. It can be done with a sliding
plank.

[_The_ DOCTOR _draws nearer to_ MORRIS, _who faces about,
addressing him passionately._

MORRIS. You were right on the spot, Doc, when you talked about that red
lamp of yours. That red lamp is the light of science that will put out
all the lanterns of your turnip ghosts. It's a consuming fire, Doctor,
but it is the red light of the morning. [_Points at it in exalted
enthusiasm._] Your priests can no more stop that light from shining or
change its colour and its radiance than Joshua could stop the sun and

[_The lamp at the end of the garden turns blue. They all look at it

MORRIS. [_Violently._] No, Priest, I will not let it alone. [_Pacing the
room again._] Could it be done with mirrors? [_He clasps his brow._] You
have a mirror.... [_Suddenly, with a shout._] I've got it! I've got it!
Mixture of lights! Why not? If you throw a green light on a red
light....

[_Sudden silence._

SMITH. [_Quietly to the_ DOCTOR.] You don't get blue.

DOCTOR. [_Stepping across to the_ CONJURER.] If you have done this
trick, for God's sake undo it.

[_After a silence, the light turns red again._

MORRIS. [_Dashing suddenly to the glass doors and examining them._] It's
