A young Philadelphian travels toward St. Louis dreaming of a soldier's life, but his first adventure wounds his dignity. Weak from fever, he tumbles down a staircase with Leon, a huge mastiff. When he strikes the dog with the flat of his sword, its mistress, Pelagie, calls him a brute.

A tumble down the stairs starts a feud
The story is told by a rosy-cheeked young Philadelphian who dreams of life as a soldier of fortune. He travels down the Ohio and the Mississippi with Captain William Clarke, bound for St. Louis. He wakes at Cahokia weak from fever, hating his girlish curls and fearing the laughter of the young women below.
Then a great mastiff named Leon bounds down the hall, and man and dog roll down the polished staircase in a heap. The dog springs at him, and he strikes the beast with the flat of his blade. A girl in pale satin throws her arms around the dog and calls him a brute. Her name is Pelagie, and he answers with icy courtesy before storming out.
Across the river, at a breakfast of many toasts, he toasts the fairest lady in town. The table names Dr. Saugrain's ward, the Rose of St. Louis. She is the very girl he has just insulted. A proud young man's first blunders mark the road to the woman he will love.
