"That's what I was taught in school, sir."
"If that hypothesis is true, we are rolling through space at the rate of about sixteen miles a minute," figured the banker. "Now you say heaven is up there."
"Yes, sir."
"Biggs, what time is it?"
The servant glanced at the great clock in the corner.
"Ah, it's twelve o'clock, sir, and time for your medicine," in a voice full of relief.
"Never mind the drugs," commanded McMasters, "until we finish our problem in higher mathematics. Now, if I ask you where heaven is at midnight, which will be twelve hours from now, where will you point," triumphantly.
"Why, up there," replied the bewildered servant, again indicating the ceiling.
"Then," cried McMasters, "you will be pointing directly opposite from the place you indicated a moment ago; for by midnight the earth will have turned approximately upside down. Do you get my point?"
"Yes, sir," replied poor Biggs, thoroughly befuddled.
