All licenses issued by the Board shall expire on December 31 of the year in which issued. Every pilot who holds a license as a branch pilot shall appear before the Board every twelve months, and, if the Board deems him qualified, it shall renew his license, which shall continue his term of office for one year following each renewal. Upon each renewal he shall appear before the clerk before whom he originally qualified, and renew his oath of office, but the bond given by him shall remain in force.
