This small detail reflects the changes that occurred in San Mateo County after 1863, when the railroad completed a connection between San Francisco and the farming village of San Mateo to the south. Formerly rural farms soon gave way to the country estates of California's new wealthy residents. One of those residents, a successful entrepreneur named William Howard, commissioned Carleton Watkins to photograph his lavish estate with its monumental olive tree.
