    CHARACTERISTICS OF FIBRES. completely hidden by the thickening of the side walls. (See Plate IV., fig. 7.) Straw fibres are very similar in appearance to esparto, but they are shorter and more highly polished, thus tending to make their felting power much less, and rendering paper made from them very brittle. (See Plate IV., fig. 8.) Wood fibres vary with the different species from which they are obtained and the methods used to isolate them. Pine wood is capable of yielding long, soft, transparent, flexible fibres, well suited to the pro¬ duction of strong well-felted papers. Ash and similar trees yield short, hard fibres, possessed of no great felting properties. (See Plate III., fig. 5.)
