Professor De Risque, anxious to escape for a time the too-solicitous attention of Madame De Risque, arrives at Roaring Gulch and, noting that the town's population includes many very pretty girls, he hangs out his shingle announcing the fact that he teaches piano and violin. As the professor is charming and the young ladies are impressionable, they readily desert the constant cowboys for the professor. The cowboys get their heads together and plan a counter-move. They hire a music teacher in the person of Mademoiselle Dulcie, and install her in an adjoining office to De Risque. The boys express a preference for the trombone and the clarionette and find that it is necessary to practice hard, especially when the professor is making soulful harmony with one of the village ladies. A twofold crisis occurs. Mademoiselle has all the boys literally at her dainty feet. She sends for her husband, who is a jewelry drummer. He arrives and sells the boys engagement rings at double seaside-resort prices, and after Dulcie has received a proposal and a ring from each of the boys, she departs with her hubby and sends the boys her regards and thanks. Madame De Risque traces the professor and leads him kindly, but very firmly, home.
