The grass wrack is not one of the true grasses, however, for it has real flowers, which grow in a kind of sheath formed by one of the shorter leaves. And its stem creeps along under the muddy sand, and throws up leaves at intervals, very much like that of the common bracken. On many parts of the coast it grows in the greatest abundance. There are large fields of it, so to speak, below low-water mark, which afford refuge for all kinds of small sea-creatures. Indeed, if you want to catch these animals for yourself, the very best way to do it is to wait until the tide is quite low, and then to wade into the water and fish about in the masses of grass wrack with a small net. [Illustration: PLATE XLVIII 1. CARRAGEEN MOSS. 2. THE SEA GRASS. 3. THE GRASS WRACK.] Great quantities of the long, narrow leaves of this plant are often flung up on the shore; and when they have been thoroughly dried they are often used for packing glass or china, instead of hay or straw.
