My principal object in writing this book is to present phases of life in nomadic North-East Africa, and to supply detailed information of a nature that might prove useful to travellers and sportsmen who wish to visit that country. As my brother and I have always been pioneering, the men who have followed in our footsteps have naturally had better opportunities for sport than we had, and I only give such of my more successful sporting experiences as will assist me in my main object of giving a general portrait of the country.

With reference to the following pages of my book, I would say that I merely present a collection of facts. To write a continuous narrative of my movements, in a manner to hold the interest of the reader throughout, requires a special literary gift such as I do not possess. The careful notes of all that came within the observation and experience of my brother and myself, during our ten thousand miles of wanderings with camel caravans, are here collected and presented in their most simple form. Most of the illustrations are direct reproductions of my own drawings, representing incidents I have seen, for the artistic merit of which I must beg my readers’ indulgence.

My thanks are due to Brigadier-General J. Jopp, C.B., A.D.C., British Resident at Aden; and to Lieut.-Colonel E. V. Stace, C.B., Political Agent and Consul for the Somáli Coast; and to many officers of the Aden Political Staff under whom I have been employed, or with whom I have been associated, for many kindnesses and hospitalities extended to me in Aden and the Somáli Coast ports; and to my brother, Captain E. J. E. Swayne, 16th Bengal Infantry, for the use of his journals and sketches, for all his valuable and indefatigable assistance, to say nothing of his saving my life in a plucky and skilful manner under circumstances the difficulty of which only sportsmen can fully appreciate. My best thanks are also due to Prince Boris Czetwertynski and Mr. Seton Karr for having given me permission to reproduce some of their beautiful and artistic photographs; to Captain H. M. Abud, Assistant Resident at Aden, for many hospitalities, and for his kindness in having supplied me with the historical notes given in the first chapter.

I am also greatly indebted to Lieut.-General E. F. Chapman, C.B., Director of Military Intelligence, and to Lieut.-Colonel J. K. Trotter, and other officers of the Intelligence Staff, for having permitted me to use and to copy a reduction of my routes, which was made under their direction; and also to Mr. W. Knight for the excellent manner in which he has designed and drawn the maps which accompany this book. My third chapter is rewritten from articles which have already been published in the Field in 1887, and I have to thank the Editor of that paper for his courtesy in having allowed me to make use of them here.

I have to thankfully acknowledge the kindness of Dr. P. L. Sclater, Secretary of the London Zoological Society, for having permitted me to rewrite and amplify, in my supplementary chapter, two papers upon Antelopes which were written by me for that Society and published in its Proceedings.

Finally, I would express my gratitude to Mr. Rowland Ward, who has devoted so much valuable time and experience to the production of my book.
