Between 1900 and 1905 furniture factories and planing mills became somewhat important.
Frostburg is in the midst of the coal region of the state, and is itself almost completely undermined; it has planing mills and manufactures large quantities of fire-brick.
Other leading manufactures are malt liquors ($21,620,794 in 1905), railway rolling-stock consisting largely of cars ($21,428,227), men's clothing ($18,496,173), planing mill products ($17,725,711), carriages and wagons ($16,096,125), distilled liquors ($15,976,523), rubber and elastic goods ($15,963,603), furniture ($13,322,608), cigars and cigarettes ($13,241,230), agricultural implements ($12,891,197), women's clothing ($12,803582), lumber and timber products ($12,567,992), soap and candles.
The lumber industry is important: in 1905 the total factory product of lumber and timber was valued at $10,901,650, and lumber and planing mill products were valued at $1,690,455.
The principal industries are shipbuilding (iron), boiler and engineering works, iron and brass foundries, steam saw and planing mills, flour-mills, paper and paint factories, and soapworks.
