sedge, segge

[A. S. seeg; Low Ger. segge; Sw. & Gael. siesg; Wel. hesg. Skeat considers it to be from the Teutonic base, seg to cut.] [SEG.] I. Ord. Lang.: Generally in the sense II. 2, but sometimes more vaguely. II. Botany : 1. The genus Carex (q. v.); also Cladium. 2. ( Pl.): The Cyperacese (q. v.). †sedge-bird, s . Ornith.: The Sedge-warbler (q. v.). "Worms, slugs, and various aquatic insects form the chief food of the Sedge - bird , but Naumann states that in autumn it will eat elder-berries."-Yarrell: Brit. Birds (ed. 4th), i. 379. sedge-warbler, s. Ornithology: Acrocephalus schœnobænus, a small European singing bird. Its total length is rather le than five inches; tail comparatively short; upper surface rufous-brown, clouded with a darker shade; breast, belly, and lower tail-coverts pale chin, bench; go, gem; thin, this; strata which it calls into existence may consequently be lacustrine, fluviatile, or marine. It often alters its area of deposition; thus, if a lake which intercepted it be filled up, it may pa along a river traversing that lake, and be deposited many miles away in the sea. Volcanic movements altering the levels of a country affect it greatly. It is of the same color as the materials from which it was derived, if these are homogeneous. Itis perpetually deposited through the globe on a colo al scale, and has in proce of ages created the sedimentary rocks. The International Geological Congre (1881) recommended the following terms for describing sedimentary strata: A group requiring an era , a sys tem requiring a period , a series requiring an epoch , and a stage requiring an age for its deposition. A stage is divided into beds, for which a correspond-ing chronological term has not yet been fixed. On this plan one would speak of the Secondary or Mesozoic group and era, the Oolitic system and period, the Upper Oõlite series and epoch, and the Middle Purbeck stage and age.
