The passengers of the _Korosko_ formed a merry party, for most of them had travelled up together from Cairo to Assouan, and even Anglo-Saxon ice thaws rapidly upon the Nile. They were fortunate in being without the single disagreeable person who in these small boats is sufficient to mar the enjoyment of the whole party. On a vessel which is little more than a large steam launch, the bore, the cynic, or the grumbler holds the company at his mercy. But the _Korosko_ was free from anything of the kind. Colonel Cochrane Cochrane was one of those officers whom the British Government, acting upon a large system of averages, declares at a certain age to be incapable of further service, and who demonstrate the worth of such a system by spending their declining years in exploring Morocco, or shooting lions in Somaliland. He was a dark, straight, aquiline man, with a courteously deferential manner, but a steady, questioning eye; very neat in his dress and precise in his habits, a gentleman to the tips of his trim fingernails. In his Anglo-Saxon dislike to effusiveness he had cultivated a self-contained manner which was apt at first acquaintance to be repellant, and he seemed to those who really knew him to be at some pains to conceal the kind heart and human emotions which influenced his actions. It was respect rather than affection which he inspired among his fellow-travellers, for they felt, like all who had ever met him, that he was a man with whom acquaintance was unlikely to ripen into a friendship, though a friendship when once attained would be an unchanging and inseparable part of himself. He wore a grizzled military moustache, but his hair was singularly black for a man of his years. He made no allusion in his conversation to the numerous campaigns in which he had distinguished himself, and the reason usually given for his reticence was that they dated back to such early Victorian days that he had to sacrifice his military glory at the shrine of his perennial youth.
