At the end of the 19th Century, there was a keen interest in exploring East Africa. There was a considerable difference of opinion among the European powers regarding control over vast expanses of unexplored territory. Appropriate boundaries between existing political entities proved difficult to define. This book presents the experiences of an articulate eyewitness, a participant in the process of exploration and boundary demarcation. Bright’s diary entries are remarkable for their detail and insight. He was a candid observer of places that were at the time largely unknown to the outside world. He was a meticulous record-keeper with a keen eye for details. His diaries thus offer an unusual insider’s look at the evolution of British colonial policy, as well as provide a factual account of daily life on these expeditions. In presenting this diary, it is the editor’s hope that an obscure but important aspect of the history of East Africa in the late 19th century will be illuminated. The introductory material is designed to make its significance more apparent to those who are not familiar with the times and places involved.
