At a signal made by Agelastes, the door of this romantic retreat was opened by Diogenes, the negro slave, to whom our readers have been already introduced; nor did it escape the wily old man, that the Count and his lady testified some wonder at his form and lineaments, being the first African perhaps whom they had ever seen so closely. The philosopher lost not the opportunity of making an impression on their minds, by a display of the superiority of his knowledge. "This poor being," he observed, "is of the race of Ham, the undutiful son of Noah; for his transgressions against his parent, he was banished to the sands of Africa, and was condemned to be the father of a race doomed to be the slaves of the issue of his more dutiful brethren." The knight and his lady gazed on the wonderful appearance before them, and did not, it may be believed, think of doubting the information which was so much of a piece with their prejudices, while their opinion of their host was greatly augmented by the supposed extent of his knowledge. "It gives pleasure to a man of humanity," continued Agelastes, "when, in old age, or sickness, we must employ the services of others, which is at other times scarce lawful, to choose his assistants out of a race of beings, hewers of wood and drawers of water--from their birth upwards destined to slavery; and to whom, therefore, by employing them as slaves, we render no injury, but carry into effect, in a slight degree, the intentions of the Great Being who made us all." "Are there many of a race," said the Countess, "so singularly unhappy in their destination? I have hitherto thought the stories of black men as idle as those which minstrels tell of fairies and ghosts." "Do not believe so," said the philosopher; "the race is numerous as the sands of the sea, neither are they altogether unhappy in discharging the duties which their fate has allotted them. Those who are of worse character suffer even in this life the penance due to their guilt; they become the slaves of the cruel and tyrannical, are beaten, starved, and mutilated. To those whose moral characters are better, better masters are provided, who share with their slaves, as with their children, food and raiment, and the other good things which they themselves enjoy. To some, Heaven allots the favour of kings and of conquerors, and to a few, but those the chief favourites of the species, hath been assigned a place in the mansions of philosophy, where, by availing themselves of the lights which their masters can afford, they gain a prospect into that world which is the residence of true happiness." "Methinks I understand you," replied the Countess, "and if so, I ought rather to envy our sable friend here than to pity him, for having been allotted in the partition of his kind to the possession of his present master, from whom, doubtless, he has acquired the desirable knowledge which you mention."
