Mizdah, I am inclined to divide the country, for convenience sake, into
a series of zones, or regions.

1st zone. This includes the sandy flat of the suburbs of the town of
Tripoli, with the date-palm plantations and the sand-hills contiguous.

2d zone. The mountains, or Tripoline Atlas, embracing the rising ground
with their influence on the northern side, and the olive and fig
plantations, covering the undulating ground on the southern side, where
the Barbary vegetation is seen in all its vigour and variety. This may
also be emphatically called the region of rain.

3d zone. The limestone hills and broad valleys, gradually assuming the
aridity of the Sahara as you proceed southward, between the town of
Kaleebah and Ghareeah; the olive plantations and corn-fields disappear,
entirely in this tract.

4th zone. The Hamadah, an immense desert plateau, separating Tripoli
from Fezzan.

5th zone. The sandy valleys and limestone rocks between El-Hasee and
Es-Shaty, where herbage and trees are found, affording food to numerous
gazelles, hares, and the wadan.

6th. The sand between Shaty and El-Wady, piled in masses, or heaps,
extending in undulating plains, and occasionally opening in small
valleys with herbage and trees.

7th. The sandy valleys of El-Wady, covered with forests of date-palms,
through which peep a number of small villages.
