8 8 AN EXAMINATION OF THE NEW SURVEY.

two of the smallest streams, as well as the natural division of the waters of a Hemisphere.

The New Survey is included in two great Watersheds, that of the Mediterranean Sea on the west, and that of the Jordan on the east. The main Waterparting between these sheds or slopes, runs through the map between the Jordan and the Sea coast, in a very zig-zag course, which it is difficult to follow on the map, without prominent distinction by colour or by detailed description. About three-fourths of the country west of the Jordan are on the Mediterranean slope. The Basins of the Mediterranean Watershed will be examined first, then those of the Jordan. Afterwards the Orography or Eelief of the country, its Plains and Highlands, will undergo a systematic examination, bringing out the dis- tinctive forms of the ground, taking further notice of. the Valleys, and rendering the intricate combination of the moun- tains intelligible. This will be the limit of the present work ; but other investigations will follow.
