Laughing, Jack provided the colored man with one of the torches,
instructing him how to use it, and presently Washington was seen
outside, walking gingerly around, as though he expected to go through
the crust of the moon any moment. Pretty soon, however, he got more
courage and tramped boldly along, peering about on the ground for all
the world, as Mark said, as if he was looking for chestnuts.

They paid no attention to the cook for some little time until, when the
boys and the two professors were in the midst of a discussion as to
where would be the best place to move the projectile next, they heard
him running along the corridor toward the cabin.

"Wash is in a hurry," observed Jack.

The next instant they sprang to their feet at the sight of the
frightened face of the colored man peering in on them. He was as near
white as a negro can ever be, which is a sort of chalk color, and his
eyes were wide open with fear.

"What's the matter?" asked Jack.

"A ghost! I done seen de ghost ob a dead man!" gasped the colored man.

"A ghost?" repeated Mark.

"Yais, sah, right out yeah! He's lyin' down in a hole--a dead man.
Golly! but I'se a scared coon, I is!" and Washington looked over his
shoulder as though he feared the "ghost" had followed him.
