W. J. Little was the contractor.","why_significant":"The nomination argues the mill is a notable example of turn-of-the-century industrial design using Classical motifs, and the largest and only surviving industrial building of its type and period in Eureka. It was also the area's only major industrial complex not tied to fishing or lumbering, and it was a major part of the regional economy. Its construction uses redwood in ways unique to the Humboldt Bay area.","narrative":"Built in 1900 at the corner of Broadway and Fourteenth Street in Eureka, this two-story woolen mill was put up for a company formed after a San Francisco promoter pitched the idea to local investors. W. J. Little was the contractor, and the mill began limited production in November 1900. The wood-frame building is made almost entirely of native redwood, including laminated redwood walls and beams and redwood decking, and carries Howe trusses over a large open loom floor. Its proportions and details are a vernacular take on Greek Revival. Additions were made in the early 1900s and through the 1920s, including a large drying shed. Wool milling ended in the mid-1940s, after which the building housed various commercial uses. It was listed as the only surviving industrial structure of its type and period in Eureka and as the one major local industry outside fishing and lumbering. Owners planned to restore its historic appearance.","period_of_significance":"1900- (specific dates 1900, altered 1920s)","architect_builder":"W. J.
