About one o'clock
Their shouts were lost in the thousand cheers with which the passengers greeted 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 .
