without a cloud. We were at sea⁠—there is no other adequate expression⁠—on the plains of Nebraska. I made my observatory on the top of a fruit-wagon, and sat by the hour upon that perch to spy about me, and to spy in vain for something new. It was a world almost without a feature; an empty sky, an empty earth; front and back, the line of railway stretched from horizon to horizon, like a cue across a billiard-board; on either hand, the green plain ran till it touched the skirts of heaven. Along the track innumerable wild sunflowers, no bigger than a crown-piece, bloomed in a continuous flowerbed; grazing beasts were seen upon the prairie at all degrees of distance and diminution; and now and again we might perceive a few dots beside the railroad which grew more and more distinct as we drew nearer till they turned into wooden cabins, and then dwindled and dwindled in our wake until they melted into their surroundings, and we were once more alone upon the billiard-board. The train toiled over this infinity like a snail; and being the one thing moving, it was wonderful what huge proportions it began to assume in our regard. It seemed miles in length, and either end of it within but a step of the horizon. Even my own body or my own head seemed a great thing in that emptiness.
