In less than two hours and a half they were through the Rockies, and
the "Albatross" resumed her former speed of sixty-two miles an hour.
She was steering southwest so as to cut across Utah diagonally as she

And then, in obedience to an order secretly given, the "Albatross"

the doors of the cars. Then numerous passengers crowded the gangways.
Some did not hesitate to climb on the roof to get a better view of
the flying machine. Cheers came floating up through the air; but no
Robur appeared in answer to them.

The "Albatross" continued her descent, slowing her suspensory screws
and moderating her speed so as not to leave the train behind. She
flew about it like an enormous beetle or a gigantic bird of prey. She
headed off, to the right and left, and swept on in front, and hung

his voice, "I am Uncle Prudent of Philadelphia!" And the secretary
followed suit with, "I am Phil Evans, his colleague!" Their shouts
were lost in the thousand cheers with which the passengers greeted
