Now is required a special quality of the imagination, not in
myself, but in my readers, for it becomes necessary for them to
grasp the logic of a whole country in one mental effort. The
difficulties to me are very real. If I am to tell you it all in
detail, your mind becomes confused to the point of mingling the
ingredients of the description. The resultant mental picture is a
composite; it mixes localities wide apart; it comes out, like the
snake-creeper-swamp-forest thing of grammar-school South America,
an unreal and deceitful impression. If, on the other hand, I try
to give you a bird's-eye view-saying, here is plain, and there
follows upland, and yonder succeed mountains and hills-you lose
the sense of breadth and space and the toil of many days. The
feeling of onward outward extending distance is gone; and that
impression so indispensable to finite understanding-"here am I,
and what is beyond is to be measured by the length of my legs and
the toil of my days." You will not stop long enough on my plains
to realize their physical extent nor their influence on the human
soul. If I mention them in a sentence, you dismiss them in a
thought. And that is something the plains themselves refuse to
permit you to do. Yet sometimes one must become a guide-book, and
bespeak his reader's imagination.

The country, then, wherein we travelled begins at the sea. Along
the coast stretches a low rolling country of steaming tropics,
grown with cocoanuts, bananas, mangoes, and populated by a happy,
half-naked race of the Swahilis. Leaving the coast, the country
rises through hills. These hills are at first fertile and green
and wooded. Later they turn into an almost unbroken plateau of
thorn scrub, cruel, monotonous, almost impenetrable. Fix thorn
