Danny and Life on Bluff Point: My Horse Sally is the fifth in a series of historical novels for children. Danny is learning to ride his new horse and has discovered the location of Captain Charles Williamson's historic campsite-by falling into a dug well. There is no way out for him until a Seneca Indian boy discovers his plight and skillfully rescues him. Danny's new friend explains why he and his family are living near Branchport. The boy's grandfather tells an emotional story about the Seneca Indian Chief, Red Jacket.

The men of the Lee family help to launch Uncle Philo's steamboat, Cricket. During the season's exciting first ride on the lake Danny is asked to pilot the large boat and is left alone in the pilothouse. Doubt at first overwhelms him but as he turns the steamboat away from the shore he knows he can do what is expected of him. This is a very thrilling and 'grownup responsibility.

It seems that the thoughtless Mr. Overhouser will purchase Grandpa Scott's property at the tip of Bluff Point. Sister Mary and Danny are needlessly placed in a dangerous position when the careless Mr. Overhouser forces their wagon off the road while driving up the east side of the bluff.
