The Metropolitan Police Board unanimously chose one of its members, William Benning Webb who was commissioned as a Major in the army, to serve as the first Chief of Police, the formal title being "Major and Superintendent". The Police Board initially divided the District into 10 precincts. The First Precinct constituted the portion of Washington County east of the Anacostia River, while the Second Precinct included the county territory north of Washington City and between the Anacostia and Rock Creek. The Third Precinct comprised the remainder of Washington County west of Rock Creek, including Georgetown and the island of Analostan in the Potomac River. The Fourth through Tenth precincts corresponded respectively with the First through Seventh wards of Washington City. Beginning immediately, Superintendent Webb worked to organize the department which had an authorized strength of ten sergeants and as many patrolmen as needed, though not to exceed 150. The majority of the new department was hired by September with the Superintendent of Police salaried annually at $1,500, sergeants received $600, and patrolmen were paid $480. The officers worked 12-hour shifts, seven days a week with no holidays or vacation time. At first officers were issued no uniform or badges and had to purchase their own firearms. The U.S. Capitol building was chosen as the back drop of the MPD badge a month later and today's badge has changed little from the original. The first arrest by an MPD officer was for public intoxication.
