Tom Sawyer Abroad by Mark Twain

WE had an early breakfast in the morning, and set looking down on the desert, and the weather was ever so bammy and lovely, although we warn't high up. You have to come down lower and lower after sundown in the desert, because it cools off so fast; and so, by the time it is getting toward dawn, you are skimming along only a little ways above the sand.

We was watching the shadder of the balloon slide along the ground, and now and then gazing off across the desert to see if anything was stirring, and then down on the shadder again, when all of a sudden almost right under us we see a lot of men and camels laying scattered about, perfectly quiet, like they was asleep.
