Edward S. Ellis, Alden the Pony Express Rider (1909)
“ With a snort he flirted his head, as if he would shake off everything that held him back as easily as he blew aside the fleck of foam that alighted like a snowflake on the knee of his rider. With nose outstretched, mane and tail flying, and the play of each muscle like the working of a splendid machine, he flung the miles to the rear with a rapidity that was almost incredible. Almost in the same instant that the pony’s hoofs hit the plateau, the graceful limbs struck an astounding speed. Alden had no means of knowing the rate attained, but it must have been twenty-five miles an hour. ”
