Orchardists formed the union in 1892 and bought Frank Buxton’s drying works by the tracks, with about 16 acres of drying yards. In 1894 they built a brick storehouse near Central Avenue that still stands. In August 1906 the San Jose Herald reported about 75 tons of prunes a day passing through.
Support faded as growers sold elsewhere when prices rose, and the union sold out to George E. Hyde & Company in 1913.
