This series consists of correspondence regarding the payment of the tuition, room and board, and other fees incurred by Harrison's grandsons, Cyrus E. Manierre and William E. Manierre while they were students at The Hill School in Pennsylvania from 1933-1938. The boys' father, C. Edson Manierre, had failed to make the necessary payments, and Harrison agreed to help settle the boys' accounts in order to permit Cyrus to graduate with his class in June 1938, so that Cyrus could enter West Point that summer. This arrangement was not disclosed to Edson Manierre, who separately agreed to make monthly payments to The Hill School until the debt was satisfied. These monthly payments were first applied against the boys' remaining outstanding balance after Harrison's payment, and then collected by The Hill School on Harrison's behalf in order to repay Harrison the amount he had advanced on Edson's behalf. Harrison was concerned that if Edson Manierre knew that Harrison had already paid The Hill School, Edson would not make an effort to repay him. The correspondence in this series relates to the initial agreement between Harrison and The Hill School, the status of Edson Manierre's monthly payments to The Hill School, an incident that occurred immediately after William Manierre graduated from The Hill School in 1942, in which he was caught drinking, and a final dispute between Harrison and The Hill School over the issue of whether Harrison should pay a portion of the attorneys' fees incurred by The Hill School in connection with Edson Manierre's payments. Some of these letters also contain information about the actions of Harrison's grandsons during World War II.
