Winston Churchill, From “My African Journey” (1908)
Uganda is from end to end a ‘beautiful garden’ where ‘staple food’ of the people grows almost without labor. Does it not sound like a paradise on earth? It is the Pearl of Africa
My counsel plainly is – concentrate upon Uganda! Nowhere else in Africa will little money go so far. Nowhere else will results be more brilliant, more substantial or more rapidly realised
[Uganda] is alive by itself. It is vital, and in my view, in spite of its insects and diseases, it ought, in the course of time, to become the most prosperous of all our East African possessions, and perhaps the ‘financial driving wheel’ of this part of the world.
“Concentrate Upon Uganda”!
My journey is at an end, the tale has been told. The reader who has followed so faithfully and so far has a right to ask what message I bring back. It can be stated in three words:
Uganda Truly the “Pearl of Africa”
