Sheriff Finn Craig's deputies earned $75 a month in 1920, but each of them had to furnish his own horse on rural patrol---in delivering court summons and in collecting delinquent taxes. The automobile had arrived in El Dorado, to be sure, as the five blocks of pavement in and about the town square bore mute testimony, but hitching posts and livery stables were also still much in evidence---bearing proof that the county seat had not departed from its horse-and-buggy days. One of the paved blocks at the center of town extended south from the town square on Washington Street to include Rufus N. Garret's three-story brick hotel, built in 1910 or 1911, which catered mainly to overnight drummers calling on the business houses in town, but which in the past several months had accommodated a number of oil men.
