Lumber (also known as timber) is wood in any of its stages from felling to readiness for use as structural material for construction, or wood pulp for paper production.

Lumber is supplied either rough or finished. Besides pulpwood, rough lumber is the raw material for furniture-making and other items requiring additional cutting and shaping. It is available in many species, usually hardwoods, but it is also readily available in softwoods such as white pine, red pine and poplar due to their low cost per board foot. Finished lumber is supplied in standard sizes, mostly for the construction industry, primarily softwood from coniferous species including pine, fir and spruce (collectively known as Spruce-pine-fir), cedar, and hemlock, but also some hardwood, for high-grade flooring.

Famous quotes containing the word lumber:

    The bookful blockhead, ignorantly read,
    With loads of learned lumber in his head.
    With his own tongue still edifies his ears,
    And always listening to himself appears.
    Alexander Pope (1688–1744)

    To drive Paul out of any lumber camp
    All that was needed was to say to him,
    “How is the wife, Paul?” and he’d disappear.
    Robert Frost (1874–1963)

    Then cut down the trees when lumber grown,
    And there’s your pristine earth all freed
    From lovely blooming but wasteful weed
    And ready again for the grass to own.
    Robert Frost (1874–1963)
