INTRODUCTION, XX

has at the present time stored in Ladé 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, but 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

vlil. 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 Rol, Makrakd, and Monbuttu, which had been previously governed by Mula Effendi, were transferred to Emin’s jurisdiction.
