LOOMIS BASIN HISTORICAL SOCIETY’S THROWBACK THURSDAY: Secret Ravine Postmasters – Horace Hart and John Agan
In the early days, postmasters in the Secret Diggings mining district changed often. The first post office along Secret Ravine was aptly named the Secret Ravine Post Office. It was established on August 29, 1854, with Horace G. Hart, postmaster.
Horace Hart was from Holden, a small town near Bangor Maine. He grew up on the old Hart homestead, where his father was an energetic farmer who did his own blacksmithing and made shoes for his thirteen children.
Horace adventured to California, sailing on the ship Charles Cooper, bound for San Francisco, in November 1849. With Granville Wall, a fellow native of Maine, he mined for gold at Placerville. The two then made their way to Stewart’s Flat, on Secret Ravine, where Horace was appointed the first postmaster in 1854. He most likely kept the post office at Granville’s store, called the Wall House.
Horace perhaps left his friend in charge of the mail while he returned to Maine to marry Miss Lydia Tibbetts in 1858. Bringing his bride to California, he settled near San Jose. He lived there until his death in 1877.
Secret Ravine’s second postmaster was John S. Agan. He replaced Horace Hart on January 18, 1860. The story of John’s life is elusive. He was from Indiana. When he arrived in California is unknown. He served as Secret Ravine postmaster for one year, then was reappointed six months later and held the post until March 25, 1863.
Sometime, probably in 1862, John was elected constable of Township 9, which encompassed the entire Secret Diggings mining district from present-day Newcastle to Rocklin. He was the local law until early 1865. With the arrival of the railroad in 1864, he became a “retail liquor dealer” in Newcastle. Perhaps he had a saloon. With John Hanson and John Mitchell, he organized a social ball in Newcastle on April 16, 1864. He is next seen in August 1865 serving as an election judge at Clipper Gap. By 1871, he had moved further up the hill and was keeping a saloon at Cisco.
