From a demographic and statistical view of the subject, its truly Malthusian results become at once shockingly and persistently prominent,--not alone in the interference that the condition induces in arresting any further procreation on the part of the unfortunate victim, but in the unparalleled mortality that, in the gross, is made necessary by the results of the operative procedures. The Soudan alone furnished, according to reliable statistics, some 3800 eunuchs annually, the material coming from Abyssinia and the neighboring countries, it being gathered by war and kidnapping parties, or by purchase, from among the young male population of those regions. These children are brought to the Soudan frontier and custom duties are there paid for their passage across the border, the duty being about two dollars per head. At Karthoum they are purchased by pharmacists, apothecaries, and others engaged in the manufacture of eunuchs, who generally perform simple castration; the mortality among these amounts to about 33 per cent. These simply castrated eunuchs bring about $200 apiece. The great eunuch factory of the country, however, is to be found on Mount Ghebel-Eter, at Abou-Gerghe; here a large Coptic monastery exists, where the unfortunate little African children are gathered. The building is a large, square structure, resembling an ancient fortress; on the ground-floor the operating-room is situated, with all the appliances required to perform these horrible operations. The Coptic monks do a thriving business, and furnish Constantinople, Arabia, and Asia Minor with many of their complete, much-sought-for, and expensive eunuchs. They here manufacture both grades,--those who are simply castrated and those on whom complete ablation of all organs has been performed, the latter bringing from $750 to $1000 per head, as only the most robust are taken for this operation, which nevertheless, even at the monastery, has a mortality of 90 per cent.
