The Mating (1918)

While her eccentric father perfects his latest invention, Nancy Fane wonders how she will clothe her brothers and sisters, and Mammy contemplates stealing the neighbor's chickens for dinner. One day Nancy hears a noise in the abandoned house next door and summons the sheriff, who reveals that the intruder is really Dick Ives, the house's owner. A novelist who hopes to win a prize for his new novel, Dick becomes so convinced of the value of Mr. Fane's invention that when a crooked promoter tries to buy it for a very low sum, Dick spirits it away to his room. Believing him a crook, Nancy shuns Dick's company, even after he contracts pneumonia while rescuing her sister from drowning. When Dick's contact with an engineering firm leads to a large check for her father's invention, however, Nancy enters the sick man's room and rushes his manuscript to the publisher, with the result that Dick wins both the prize and the girl next door.
