"By filling the vestibule as full as possible," said Bearwarden, "and
so displacing most of its air, we shall be able to open the outside
door oftener without danger of rarefaction."

The things they had discharged flew off with considerable speed and
were soon out of sight; but it was not necessary for them to move fast,
provided they moved at all, for, the resistance being nil, they would
be sure to go beyond the range of vision, provided enough time was
allowed, even if the Callisto's speed was not being increased by
apergy, in which case articles outside and not affected would be
quickly left behind.

The earth, which at first had filled nearly half their sky, was rapidly
growing smaller. Being almost between themselves and the sun, it
looked like a crescent moon; and when it was only about twenty times
the size of the moon they calculated they must have come nearly two
hundred thousand miles. The moon was now on what a sailor would call
the starboard bow--i. e., to the right and ahead. Being a little more
than three quarters full, and only about fifty thousand miles off, it
presented a splendid sight, brilliant as polished silver, and about
twenty-five times as large as they had ever before seen it with the
unaided eye.

It was just ten hours since they had started, and at that moment 9 A.
M. in New York; but, though it was night there, the Callisto was bathed
in a flood of sunlight such as never shines on earth. The only night
they would have was on the side of the Callisto turned away from the
sun, unless they passed through some shadow, which they intended to
avoid on account of the danger of colliding with a meteor in the dark.
The moon and the Callisto were moving on converging lines, the curve on
which they had entered having swung them to the side nearest the earth;
but they saw that their own tremendous and increasing speed would carry
them in front of the moon in its nearly circular orbit. Wishing to
change the direction of their flight by the moon's attraction, they
shut off the power driving them from the earth, whereupon the Callisto
turned its heavy base towards the moon. They were already moving at
such speed that their momentum alone would carry them hundreds of
thousands of miles into space, and were then almost abreast of the
earth's satellite, which was but a few thousand miles away. The
spectacle was magnificent. As they looked at it through their field
