This section is from the "Practical Banking" book, by Albert S. Bolles.
In many Savings banks the duties which have been described as shared between the treasurer and secretary, are divided between the president and treasurer, or the president and secretary. The president is usually not a salaried officer, and in that case his duties-are practically confined to presiding at the monthly meetings. He is rather president of the board of trustees than president of the bank. In other institutions he receives a small salary, attends daily, but not during the entire session, and has no routine duties, but superintends and advises in all departments. He is required by the by-laws to execute all deeds, releases, satisfactions, or other documents in the nature of a conveyance of real estate, and to countersign all checks. Although it may seem wasteful to employ an officer of a corporation with no stated routine duties, yet where the trust is large the writer thinks emphatically that this should be the case—that the duties of the highest officer should be entirely discretionary with himself, and that he should possess such an intimate and also such a broad knowledge of the business that he himself is the best judge of what department needs his personal attention, and that he himself can be held responsible for everything.
