My journey among the cave dwellers of Southern Tunisia was essentially one of research, since I was entrusted by Doctor Sophius Müller, Director of the Second Department of the National Museum, with the honourable task of purchasing ethnographical objects for the said museum.

On submitting this work to the public, it is incumbent upon me to offer my sincere thanks to all those who afforded me support and help in my travels: the Minister of Foreign Affairs, at whose recommendation Cubisol, the Danish Consul in Tunis, addressed himself to the French Regency, and obtained permission for me to travel through the country, and also an escort, guides, etc. Doctor Müller and Chamberlain Vedel, whose respective introductions, given from the National Museum and the Society concerned with ancient manuscripts, and addressed to other similar institutions, introduced me not only to these, but also to those remarkably scientific men, Gauckler and Doctor Bertholon, whose friendship I have to thank for much information and assistance.

England’s Representative in Tunis, Drummond Hay, may be said to have traced my path through Tunisia, as, on the basis of his remarkable knowledge of both individuals and of relative circumstances, he sketched a plan of my journey, from which I required to make little or no deviation. The Government and officers in El Arad, the officials, both military and civilian, showed me the greatest hospitality, and assisted me in the highest degree; Colonels Billet and Gousset especially claim my warmest gratitude.

Much of what I have recorded has been left in its original form, namely, as letters written home, some to my wife, some to other persons, as, for instance, to the publisher, Herr Hegel. I have not altered these lest they might lose the fresh impression under which they were written. Several portions were composed with a view to publication in the French journal the Revue Tunisienne, and in the Parisian magazine Le Tour du Monde.

The illustrations were obtained from various sources. Albert, the photographer in Tunis, obligingly allowed me to make use of a number of photographs, from which were chiefly drawn the views of the town and of the sea-coast. With a detective camera I myself took some instantaneous photographs on the journey from Gabés to the mountains, of which a number are introduced. Besides these, Mr. Knud Gamborg has engraved some drawings of my own. Mr. Gauckler also gave me the free use of the sketches already published in his Collection Beylicale, from which were selected the pictures of the villages in the Matmata mountains. Lastly, from the wife of Consul Henriksen at Sfax I received two paintings, which are reproduced.

When, in the spring, I made an expedition to Greenland, I left my manuscript with my friend Doctor Kragelund, of Hobro, who had already afforded me his assistance, and gave him full powers to arrange the somewhat heterogeneous materials. In my absence he corrected the proofs as they came from the press, and has therefore taken a very important part in my work, and enabled it to be published in its present form. For this act of friendship I tender him my warmest thanks.

Note.—The fact of three years having elapsed since the Danish original of the Cave Dwellers was published, renders the letter form of which the author speaks somewhat unsuitable for translation. It has been necessary, therefore, in many cases to modify that form, and also to omit certain passages in the work as being of little or no interest to English readers.
