Magnolia plantation:
The home of the Eclipse Brass Band.
"Magnolia Plantation is significant in the history of American agriculture as one of the largest and most intact plantation complexes in the southern United States. The site contains a collection of extremely rare slave cabins. Magnolia also retains its cotton pressing and ginning equipment. The late nineteenth century system gin is an extremely rare survivor within the region, as is the antebellum screw press. Considered in context with extant structures on the plantation, cotton gins are potentially a powerful tool with which to interpret the American Souths quintessential industry, the production of raw cotton. The period of significance spans from c.1835, the date of the earliest building, to 1939, when Magnolia, following a trend across the South during the 1930s and 40s, stopped ginning its own cotton." http://tps.cr.nps.gov/nhl/detail.cfm?ResourceId=-1953832489&ResourceType=District
- The plantation was one of the largest and most successful in the Delta country south of New Orleans, and was also known as Lawrence Post Office. It was given over to sugar production. The owner was Governor Henry Clay Warmoth. Warmoth purchased instruments and started paying James Humphrey to instruct a brass band in March 1897.
Prominent musicians that came from the plantation were Sunny Henry and Harrison Barnes.

Normally called, "Second Lines", the sponsoring element is called the "Main Line" and is usually a Social (Aide) & Pleasure Club of the neighborhood in which they are parading.
