As the author himself writes: "The doctor finds his sphere everywhere, and his hands are full of work as soon as he arrives (at his station). He is able to overcome suspicion and prejudice, and his kindly aid and sympathetic treatment disarm opposition, while his life is a better setting forth of Christianity than his words. There is a door everywhere which can be opened by love and sympathy and practical service, and no one is more in a position to have a key for every door than a doctor." These few words fairly sum up the situation, and I fully agree with the view they express. On such a wild frontier as that on the North-West Border of India the life of a doctor-missionary is beset with many perils. A perusal of Dr. Pennell's most interesting story shows that he has had his share of them, and that in the earnest and zealous discharge of his duties he has faced them bravely and cheerfully. I cordially recommend his book to all readers, and my earnest hope is that medical missions will continue to flourish. ROBERTS, F.M. December 19, 1908. PREFACE After sixteen years of close contact with the Afghans and Pathans of our North-West Frontier in India, I was asked to commit some of my experiences to paper. The present book is the result. I have used the Government system of transliteration in vernacular names and expressions, and I beg the reader to bestow a few minutes' consideration on the table of corresponding sounds and letters given on p. xvi, as it is painful to hear the way in which Englishmen, who, with their wide imperial interests, should be better informed, mispronounce common Indian words and names of places which are in constant use nowadays in England as much as abroad. Nothing is recorded which has not been enacted in my own experience or in that of some trustworthy friend. In Chapters XIII. and XIV. it would have been unwise to give the actual names, so I have put the experience of several such cases together into one connected story, which, while concealing the identity of the actors, may also make the narrative more interesting to the reader; every fact recorded, however, happened under my own eyes. In Chapter XXII., the night adventure of Chikki, when he met an English officer in disguise, was related by him to me of another member of his profession, and not of himself. I wish to thank the Church Missionary Society for allowing me to reproduce some articles which have already appeared in their publications, notably Chapter XX. and part of Chapter IV. I tender my best thanks to Major Wilkinson, I.M.S., Major Watson, H. Bolton, Esq., I.C.S., and Colonel S. Baker, for some of the photographs which have been here reproduced; and to Dr. J. Cropper for his kindness in reading the proofs.
