Nubia is very different from Egypt, picturesque rocky ranges always near the river and broken into peaks and pyramids, and all desert except the narrow selvage reclaimed by irrigation with sakias; here the vegetation (barley, peas, beans, and lupines) intensely green by the contrast with yellow sand or light brown sandstone. January 23, before reaching Korosko (whence caravans to Dongola; visited their camps, very wild Arabs and blacks, and very disagreeable white traders, Greeks, probably, with villainous faces) saw our first crocodile, and sent two shots at once at him, but the huge fellow flounced off the sand bank into the river, probably not much hurt. January 24, first met with chameleons; got three or four from the boys, but finally kept only one, which we still have here at Cairo--a lovely little brute whose name is Billy, and a great pet; a great diversion to watch his change of hues, and especially to see him catch flies by darting out his slender, india-rubber-like tongue to the length of several inches (nearly that of his whole body when the fly was far enough off), and with wonderful quickness and certainty. Service in the afternoon, with Church’s last sermon, and sorry we were to have reached the end of them. But I shall never have done with our journey at this rate, and shall give you not the least idea of it after this fashion; how some days we sailed on with fair winds, which is very cheerful; some we tracked, and then we were much on shore and mingled with the people; and often strong head winds kept us fast at the bank, sometimes for two or three days, which grew tedious. Well, on the 27th we came to the great attraction of the upper Nile, Abou-Simbel; but the wind being fine and fair, sailed on at a great rate, and reached our terminus, Wady Halfeh, next morning. Made next day excursion to the farthest point, the high rock Abou Seir, which dominates the second cataracts, and gives extensive view beyond, far into Africa; head winds next day kept us at the village, which we explored and exchanged hospitalities with the inhabitants, the poorer part of which were beginning to suffer from famine. Later, going down, we met boat loads of corn for seed and food going up from the viceroy for their relief; little enough to do for a people so cruelly oppressed and peeled as the fellahs are. At evening we could be off, the great yard and sail now down, and small mizzen in its place, to use on the rare occasion of a south wind, and now we depend upon the current and oars, five on each side, handled by our stalwart crew, their strokes timed by queer Arabic chants; more severe labor than in ascending (except when tracking) and not so pleasant to us as sailing; but yet we could come down much faster than we came up. Whenever there was sight-seeing by day the crews would usually row all night, so we got on finely. MESSINA, March 24.
