Xll PREFACE. 



which contains objects strikingly similar to those of Scandi- 

 navia ; also to my friends Mr. J. S. Keltic and Mr. Arthur 

 L. Eoberts ; to my old friends Messrs. Clowes, who have 

 taken great pains in carrying out what has proved to be a 

 very difficult task for the printer, and who have had the work 

 over two-and-a-half years in type. 



I must thank, above all, my esteemed and venerable pub- 

 lisher, John Murray, for the great interest he has taken in the 

 present work, which has tried his patience and liberality many 

 a time, and also for the many years of uninterrupted friendship 

 and the pleasant business relations (unhampered by any written 

 agreement whatever), which have existed between us from, the 

 time when I came to him almost a lad, and he first undertook 

 the publication of ' Explorations in Equatorial Africa,' in 1861, 

 not forgetting my dear friends, his sons, John and Hallam, 

 the former of whom has assisted me materially in seeing the 

 work through the press, and my old companion Kobert Cooke. 



I cannot close this preface without thanking my old and 

 ever true friend Eobert Winthrop, of New York, descendant 

 of the celebrated Colonial Governor of Massachusetts, to whom 

 I dedicated " The Land of the Midnight Sun," for his unfail- 

 ing kindness and sympathy during the years I have been 

 engaged in the present work.
