To raise Bruce's character by undervaluing that of other travellers would be an unworthy jealousy, in which we should be very sorry to indulge; yet the proper mode of penetrating Africa is a problem of such vital importance to those who may hereafter attempt it, that we cannot refrain from observing what a very remarkable difference there is between the manner in which Bruce and Burckhardt travelled between Egypt and Nubia. The former possessed the magic art of commanding, at all times, respect; and the reader has seen what was his behaviour, and the treatment which he received during this perilous undertaking. Burckhardt's resolution was unconquerable, and his patience in the desert almost equal to that of the camel. Science had never a more faithful servant; but then he neglected to seek information by giving it, and the disguise under which he travelled concealed not only his person, but his mind. All civilized men, from the philosopher down to the mountebank, carry with them a fund either of instruction or amusement; and the old fable of the basket-maker explains how possible it is for any one to make himself, at least, useful to uncivilized tribes; but of this Burckhardt neglected to avail himself, and a few brief extracts from his travels will show the consequences. "I gave out," he says, "I was in search of a cousin." "The son of my old friend of Daraoa, to whom I had been most particularly recommended by his father, went so far as once to spit in my face in the public market-place." "Indeed, I never met any of these Egyptians in the streets without receiving some insulting language from them, of which, had I taken notice, they would, no doubt, have carried me before the mek." "One of the slaves of Edris, to whom I had already made some little presents, tore my shirt to pieces because I refused to give it to him." "Called me boy." "I cooked my own victuals." "Was pelted with stones." "I was often driven from the coolest and most comfortable berth into the burning sun, and generally passed the midday hour in great distress." "I was afraid to take any notes." "I hid myself to do it," &c., &c., &c.... On the 11th of December Bruce embarked at Syene, and without masts being shipped or any sails set, the vessel or canja floated down the Nile. There is no greater trial to the constitution than sudden change from an active to a sedentary life: the human frame seems made for hardship; and in the army it has been constantly remarked, that troops which have been long exposed to a bivouac become unhealthy as soon as they go into quarters.
