[p.3]The principal object with which I started was this: to cross the
unknown Arabian Peninsula, in a direct line from either Al-Madinah to
Maskat, or diagonally from Meccah to Makallah on the Indian Ocean. By
what "Circumstance, the miscreator" my plans were defeated, the reader
will discover in the course of these volumes. The secondary objects

differences sufficient to warrant our questioning the common origin of
the Arab family. As regards horses, I am satisfied that from the
Eastern coast something might be done-nothing on the Western, where the
animals, though thorough-bred, are mere "weeds," of a foolish price and
