the pilot might give them occasionally, for he could leave the ship with
the steering wheel fastened, a few minutes at a time, as there was no
danger of collisions. So the _Monarch_ continued to race toward the
north.
It was almost time for Mark's tour of duty to begin. The two boys, who
were sleeping together, were in a deep slumber, when Washington ran in
and shouted at the top of his voice:
"Wake up everybody! De perfessor is killed dead!"
Andy, Mark, Jack and the two helpers sat up in their bunks, rubbing
their sleepy eyes and wondering what had happened.
"What's the matter?" asked Jack.
"Mr. Henderson is dead! He's in the engine room!"
"What killed him?" inquired Andy.
"He must hab got a shock from de dynamo!"
Andy jumped from his bunk and hurried to the engine room. There, as the
negro had described, Professor Henderson was lying white and senseless
on the floor.
The old hunter stooped over the inventor and felt of his heart.
"He is alive!" he exclaimed. "His heart beats! We must carry him to a
bunk!"
Aided by Washington, Andy carried the professor to the sleeping room,
where he was made comfortable in one of the beds. The captain was so

Washington.
"Once, but not so strong."
"What did you do for him? What medicine did he take?"
"Glory! Glory!" shouted the negro, jumping up and down in his
excitement. "I remembers it now. Wait a second!"
He hurried to the engine room, and came back in a little while with a
small bottle.
"Perfessor done say," he began, "dat if eber I seed him senselike, when
he done gone and got a shock from de 'lectrisititeness, I was to gib him
two spoons full ob dis."
Andy took the bottle, which contained a red liquid. Bill got a spoon
from the locker where the dishes were kept. With hands that trembled the
old hunter poured out some of the fluid. Then, with Jack's help he
forced open the inventor's mouth and put the medicine in.
