The
novelty of dining as comfortably as at home, yet being thousands of
miles above the earth, and, at the same time, speeding along like a
cannon-ball, did not impress our friends as much as it had during their
trip to Mars.
"Well, we're making a little better time now," observed Mark, as he and
the others rose from the table and went to the engine room. "The gauge
shows that we're making twenty-five miles a second."
"We will soon go much faster," announced Professor Roumann. "I have not
yet had a chance to test my Cardite motor to its fullest speed, and I
think I will do so. I wish to see if it will equal my Etherium machine.
I'll turn on the power gradually now, and we'll see what happens."
"How fast do you think it ought to send us along?" asked Jack.
"Oh, perhaps one hundred and twenty-five miles a second. You know we
went a hundred miles a second when we headed for Mars. I would not be
surprised if we made even one hundred and thirty miles a second with
the Cardite.
