History
One of the latest to win a large prize in African discovery is Dr. A.
Donaldson Smith, a young physician of Philadelphia, in the northeastern
region known as Somaliland and Gallaland. His method may be mentioned
here as an illustration of the kind of work that geographers now
require. Before he began his explorations, he took a thorough course in
the use of surveying instruments and the methods of accurately laying
down his positions and making a route map. Many a cartographer, burning
with desire to draw a good map of a newly explored region, has been
driven to despair by the inadequacy of the route surveys in his hands.
Not a few of these surveys have been unworthy of reproduction in the
books of the explorers who made them, and the best that could be done
was to generalize their information on maps of comparatively small
scale. But Donaldson Smith's route-maps appear in his book on the
comparatively large scale of 1:1,000,000 (about sixteen statute miles to
the inch), and they are worthy of that treatment, for his surveys and
observations for geographical positions were recorded in such a way
that their value might be easily ascertained by any one familiar with
such computations. His route-maps have been found to be admirable
map-making material; thus, he has not only traversed a new region of
great extent, but has given in his map ample materials which may be
employed by any atlas-maker in the production of good maps of all the
territory that came under his observation. When Sir Clements Markham
presented to Dr. Smith the Patrons' Medal of the Royal Geographical
Society, he said: "You have not, like an ordinary explorer, made a
common route survey, but you have made a scientific survey, a
triangulation frequently checked by astronomical observations with
theodolite and chronometer."
