I must begin my letter by retracting an opinion I expressed in my last, namely, that the defile would probably turn out a complete bugbear, as the fevers, guinea-worm, and tetse flies have done. My acquaintance with most of the passes of the Alps and Tyrol is of an extensive kind, but I confess that it in no way prepared me for the passage of an Abyssinian defile. I can now quite understand travellers warning us that many of these places were impracticable for a single horseman, much less for an army with its baggage-animals. Had not Colonel Merewether stated in his report that the first time he explored the pass he met laden bullocks coming down it, I should not have conceived it possible that any beast of burden could have scrambled over the terrible obstacles. Even now, when the Bombay Sappers have been at work for three weeks upon it, it is the roughest piece of road I ever saw, and only practicable for a single animal at once. It is in all twelve miles; at least, so it is said by the engineers, and we took, working hard, seven hours to do it; and I found that this was a very fair average time. A single horseman will, of course, do it in a very much shorter time, because there are miles together where a horse might gallop without danger. I remained at Koomaylo until the afternoon, as it was too hot to start till the sun was low. Nothing happened during the day, except the arrival of the Beloochees and Bombay Engineers. The soldiers had two or three more chases after the monkeys, of which there are extra ordinary numbers. I need hardly say that they did not catch any of them: a dog, however, belonging to one of the soldiers seized one for a moment, but was attacked with such fury by his companions that it had to leave its hold and beat a precipitate retreat. I have just been watching a flock or herd—I do not know which is the correct term—of these animals, two or three hundred in number, who have passed along the rocks behind my tent, at perhaps thirty yards’ distance. They have not the slightest fear of man, and even all the noise and bustle of a camp seem to amuse rather than alarm them. They are of all sizes, from the full-grown, which are as large as a large dog, down to tiny things which keep close to their mothers, and cling round their necks at the least alarm. The old ones make no noise, but step deliberately from rock to rock, sitting down frequently to inspect the camp, and indulge in the pleasure of a slight scratch. These full-sized fellows have extremely long hair over the head and upper part of the body, but are bare, disagreeably so, towards the caudal extremity. The small ones scamper along, chattering and screaming; they have no mane or long hair on the head. The old monkeys, when they do make a sound, bark just like a large dog. In the afternoon an enormous number of locusts came down the pass, and afforded amusement and diet to flocks of birds, who were, I observed, rather epicures in their way, for on picking up many of
