Paul Prescott's Charge is the second volume of the Campaign Series. Though wholly unlike the first volume, it is written in furtherance of the same main idea, that every boy's life is a campaign, more or less difficult, in which success depends upon integrity and a steadfast adherence to duty. Horatio Alger, Jr. authored about seventy books. He was the son of a clergyman, graduated from Harvard. His stories are pure, inspiring and as endearing today as they were when first published.
