INTRODUCTION. xxiii 



has at the present time stored in Ladu or Wadelai, prove how 

 well he understands the art of collecting. His work in the 

 districts he has explored in the eastern part of Equatorial Africa, 

 has been that of a pioneer in zoological, and especially in orni- 

 thological, subjects. The zoological work he has accomplished 

 in central Monbuttu — and it was very great, considering his 

 short stay there — is completely new, and judging from the 

 hints given in his letters, we may expect a rich harvest of 

 discoveries. A journal which Emin Pasha has sent me, bub 

 which he has forbidden me to publish at present, contains an 

 immense quantity of interesting information as to the habits of 

 the animals he has caught, with especial reference, however, to 

 birds." 



Notwithstanding all the service which Emin Pasha has 

 rendered to zoology, to which alone Dr. Hartlaub has referred, 

 it must be borne in mind that botany too has benefited to a 

 very large extent by his painstaking researches — to what ex- 

 tent will only be known when the large collection of plants which 

 he has made reaches Europe. It can easily be seen, however, 

 from his letters, what a deep interest he takes in botany, and 

 the experimental cultivations which he has carried on are of 

 immense value in proving, not only the fertility of the country, 

 but also the possibility of cultivating various commercial plants 

 in districts where their growth had been doubtful. 



To general readers, one or two chapters in this book may 

 not be quite clear. I refer especially to Parts v. 2 and 

 vii. I, in which Emin deals with the slave-trade and the 

 misery caused by the settlement of Danagla in various dis- 

 tricts. I call especial attention to this, because I have stated 

 in several publications that he had completely banished slave- 

 dealing from his province ; and so he had ; but on the recall 

 of Gessi Pasha in 1882, Lupton Bey was made Governor 

 of the Bahr-el-Ghazal province, and the provinces of Eol, 

 Makraka, and Monbuttu, which had been previously governed 

 by Mula Effendi, were transferred to Emin's jurisdiction.
