"HERE HE COMES!"

Every neck is stretched further, and every eye strained wider. Away
across the endless dead level of the prairie a black speck appears
against the sky, and it is plain that it moves. Well, I should think so!

In a second or two it becomes a horse and rider, rising and falling,
rising and falling--sweeping toward us nearer and nearer--growing more
and more distinct, more and more sharply defined--nearer and still
nearer, and the flutter of the hoofs comes faintly to the ear--another
instant a whoop and a hurrah from our upper deck, a wave of the rider's
hand, but no reply, and man and horse burst past our excited faces, and
go winging away like a belated fragment of a storm!

So sudden is it all, and so like a flash of unreal fancy, that but for
the flake of white foam left quivering and perishing on a mail-sack after
the vision had flashed by and disappeared, we might have doubted whether
we had seen any actual horse and man at all, maybe.

We rattled through Scott's Bluffs Pass, by and by. It was along here
somewhere that we first came across genuine and unmistakable alkali water
in the road, and we cordially hailed it as a first-class curiosity, and a

after we had added it to our list of things which we had seen and some
other people had not. In a small way we were the same sort of simpletons
