Luedinghaus Lumber Company was in business ca. 1908 to ca. 1929.
Dryad is a community west of Chehalis in west central Lewis County. It is one of many lumber towns that were once on the Chehalis-South Bend branch of Northern Pacific Railway. The town was once two miles south of the present location, and was called Salal. It moved when Luedinghaus Brothers of Chehalis built a sawmill at the present site. Its name, supplied by Northern Pacific Railway officials, at the suggestion of W. C. Albee, who was superintendent of the South Bend branch -- is mythological. It is for the wood nymph or dryad, who lived in oak trees. Albee figured that the dryad might get used to living in the local fir and cedar trees.
