On the artificial terraces and natural slopes of these extensive valleys the vegetables of all climates can be successfully cultivated, and the theoretical centre of successive elevations from whence, according to the hypothesis of Linnæus, all vegetation spread over the rest of the earth, appears to exist in the natural phenomena presented, by the surface geography of the Abyssinian table mountain. The country of the Gongas is similarly excavated by the deeply cut channel of the Gibbee, or the Red Nile, which, much larger than the Abi on the northern portion of the plateau, will have a greater extent of denuded valley for the production of those vegetables of a hot climate, the presence of which have been such an argument in favour of those, who contend that the water-shed of the Gibbee must be towards the lowlands in the South, where it is presumed these vegetables could only have been cultivated. The other slaves I examined at Musculo’s, were a few Amhara from Gurague, but who contributed but little to my previous information, upon the subject of their character and country. I noticed there were no Dankalli among those brought down for my inspection; and was given to understand that none of these people were ever brought into Abyssinia as slaves; and if they were, no one would purchase them, for they would neither remain with their masters, nor would they work. Even in this, their true Circassian origin is betrayed; for, although their morality does not prevent them from selling their own daughters, this caste of mankind cannot be enslaved. The superiority of this mentally endowed race is manifest, even in their most barbarous state; and I have been led, therefore, to disbelieve the general presumption, that the Negro is universally the type of man in his most degraded condition. From what I have observed myself, the Dankalli, the Shankalli, and the Bushmen, are the lowest grades of the three varieties of the human race, the Arian, or Circassian, the Amhara, or Negro, and the Gonga, or Mongolian, all of whom have a height of civilization, and a depth of barbarism distinct from each other; and that, however, the Bushman may be improved, he will only become a civilized Chinese, and that a Negro may by education be made an ancient Egyptian, but would never by that alone become the enlightened Circassian, that his neighbour, the Dankalli, could, certainly, be made. I have now exhausted, not my subject, the numerous ideas upon which I have latterly been most inconveniently obliged to crowd together, but the very limited space that I had proposed to myself in my ignorance of book-making, as being sufficient to contain all I had to say respecting my journey, and the ideas and incidents which occurred to me during my sojourn in Abyssinia. Much to my surprise, the manuscript has grown under my hand, and the greatest difficulty that I have had, has been to arrive at the period I have done, before I laid down the pen.
