the aeronef.

Three or four of the crew of the "Albatross" had appeared on the
deck, and one of them, like sailors when passing a ship less speedy
than their own, held out a rope, an ironical way of offering to tow
them.

And then the "Albatross" resumed her original speed, and in half an
hour the express was out of sight. About one o'clock there appeared a
vast disk, which reflected the solar rays as if it were an immense
mirror.

"That ought to be the Mormon capital, Salt Lake City," said Uncle
Prudent. And so it was, and the disk was the roof of the Tabernacle,
where ten thousand saints can worship at their ease. This vast dome,
like a convex mirror, threw off the rays of the sun in all directions.

It vanished like a shadow, and the "Albatross" sped on her way to the
southwest with a speed that was not felt, because it surpassed that
of the chasing wind. Soon she was in Nevada over the silver regions,
which the Sierra separates from the golden lands of California.

"We shall certainly reach San Francisco before night," said Phil
Evans.

"And then?" asked Uncle Prudent.

It was six o'clock precisely when the Sierra Nevada was crossed by
the same pass as that taken by the railway. Only a hundred and eighty
miles then separated them from San Francisco, the Californian capital.
