    "goal": "Extract intact cellulose fibers from a wide range of vegetal materials for textile, paper, and other uses.",
    "problem_addressed": "Traditional retting fails to extract usable fibers from many plants (e.g., alfalfa) and leaves material unprocessed or degraded.",
    "concept_summary": "Boutard's method uses a specially prepared ferment (the \"Proteus scum\") derived from selected plants (leguminous, chicoracees, etc.) added to a retting pit containing the target plant (e.g., alfalfa). The ferment drives a series of biological fermentations (nitrogenous, silicic, calcic, magnesic) that disintegrate non-cellular components, release gases, and leave behind a film that can be collected. The remaining plant material is then mechanically processed to yield pure cellulose fibers without the usual loss of integrity.",

After three weeks the alfalfa fibers were reported to be hardened, separated into distinct limbs, and yielded pure cellulose.",

        "At the end of approximately three weeks, the alfalfa, removed from the water, is washed and smoothly expressed between two wood rollers, lets free a portion of its chlorophyl, and its strands ... are hardened more and more obstinately closed still.",
        "The result is same and the more convincing still ... the alfalfa, thus reprocessed, gives up a portion of its silica, which is eliminated, giving under the friction of the fingers true impression of friable sandstone."
