The name of young miner Francis Marion Smith's company originated from this form of transportation. His product, known as the "Twenty Mule Team Borax," is the originator of what is still commonly used today in most homes. He discovered the huge deposits in 1870 and under research, found that it was the finest Borax ever found in California. With his profits he was able to purchase the million dollar estate known then as the Arbor Villa. His property covered five blocks of Park Boulevard and his family's home was called the "most palatial mansion in the West."

Part of Mr. Smith's land was donated to the City of Oakland in 1912 when he specified that these lands be used to provide children with a public playground. Here at F.M. Smith Recreation Center stands exact replicas of the strong mules that once pulled the heavy loads of Borax across the dry desert. The four fiber glass figures pay tribute to the fine man who so generously donated his land in the honor of children's happiness. With thanks and gratitude, the patrons of our center are able to enjoy the pleasure of a wonderful park to call their own.
