Burckhardt's first excursion was limited to the borders of the Nile, a narrow space made up of little valleys, which debouched into the river. The traveller estimated the population of the country at 100,000, distributed over a surface of fertile land 450 miles in length, by a quarter of a mile in width. "The men," says the narrative, "are, as a rule, muscular, rather shorter than the Egyptians, having little beard or moustache, usually merely a pointed beard under the chin. They have a pleasant expression, are superior to the Egyptians in courage and intelligence, and naturally inquisitive. They are not thieves. They occasionally pick up a fortune by dint of hard work, but they have little enterprise. Women share the same physical advantages, are pretty as a rule, and well made; their appearance is gentle and pleasing, and they are modest in behaviour. M. Denon has underrated the Nubians, but it must not be forgotten that their physique varies in different districts. Where there is much land to cultivate, they are well developed; but in districts where arable land is a mere strip, the people diminish in vigour, and are sometimes walking skeletons." The whole country groaned under the yoke of the Kashefs, who were descendants of the commander of the Bosniacs, and paid only a small annual tribute to Egypt, which, however, was sufficient to serve as a pretext for oppressing the unfortunate fellaheen. Burckhardt cites a curious example of the insolence with which the Kashefs behaved. "Hassan Kashef," he says, was in need of barley for his horses. Accompanied by his slaves, he walked into the fields, and there met the owner of a fine plot of barley. "How badly you cultivate your land," said he. "Here you plant barley in a field where you might have reaped an excellent crop of water-melons of double the value. See, here are some melon-seeds (offering a handful to the peasant proprietor); sow your field with these; and you, slaves, tear up this bad barley and bring it to me." In March, 1814, after a short rest, Burckhardt undertook a fresh exploration, not this time of the banks of the Nile, but of the Nubian desert. Justly conceiving poverty to be his surest safe guard, he dismissed his servant, sold his camel, and contenting himself with one ass, joined a caravan of poor traders. The caravan started from Daraou, a village inhabited partly by fellahs and partly by Ababdeh Arabs. The traveller had good reason to complain of the former, not because they recognized him as a European, but because they imagined him to be a Syrian Turk, come to share the commerce in slaves of which they had the monopoly. It would be useless to enumerate the names of the bridges, hills, and valleys in this desert. We will rather summarize the traveller's report of the physical aspect of the country.
