Broad, low, naturallevees like those of the Mississippioccur throughout the savannas, andthese are commonly wooded, whilethe interstream tracts are prairielands. Narrow belts of forest thusoccur along the waterways exceptwhere the surface has been clearedfor agriculture. Along Red River are well-wooded tracts with oak andhickory on the uplands, poplar and liquid amber on the lowlands, cypressand tupelo in the swamps. In the coastal plain of Louisiana the rivers are steep and sluggish,such as Vermilion Bayou, Calcasieu River, etc. Each of these streamsis narrow, deep, and clear, has scarcely any current, expands into abroad shallow lake, and enters the Gulf through a shallow bay. Allof them have features characteristic of drowned streams. In south-. [. — Coastal features of Texas, long, simplesand reefs enclosing narrow lagoons. 53© FOREST PHYSIOGRAPHY eastern Texas the streams of the Coastal Plain are similar to thoseof Louisiana; but west of the Nueces the coast drainage fails almostabsolutely, the whole stretch of the coast to the Rio Grande containingonly two small creeks. Though the greater part of the Louisiana-Texassection of the Coastal Plain is crossed by large rivers, a considerablepart of the surface is poorly drained. Water stands in a multitude ofsmall lakes or ponds throughout the year and there are large tractscovered with water during the wet season. The innermost belt of country belonging to the Coastal Plain risesrather rapidly from the adjacent seaward belt and has a more brokensurface with numerous, small, rounded hills. The general elevation ofthis belt does not exceed 175 or 200 feet above sea level. T
