This was quite enough for the Arabs, who had been watching the event from the opposite bank of the river, and the report quickly spread that two crocodiles were killed, one of which they declared to be the public enemy that had taken the men at the ferry, but upon what evidence I cannot understand. Although my Arabs looked forward to a dinner of crocodile flesh, I was obliged to search for something of rather milder flavour for ourselves. I waited for about an hour while the first crocodile was being divided, when I took a shot gun and succeeded in killing three geese and a species of antelope no larger than a hare, known by the Arabs as the Dik-dik (Nanotragus Hemprichianus). This little creature inhabits thick bush. Since my return to England, I have seen a good specimen in the Zoological Gardens of the Regent's Park.
Upon my arrival at the tents, I found the camp redolent of musk from the flesh of the crocodile, and the people were quarrelling for the musk glands, which they had extracted, and which are much prized by the Arab women, who wear them strung like beads upon a necklace.
A crocodile possesses four of such glands; they vary in size according to the age of the reptile, but they are generally about as large as a hazel-nut, when dried. Two glands are situated in the groin, and two in the throat, a little in advance of the fore-legs. I have noticed two species of crocodiles throughout all the rivers of Abyssinia, and in the White Nile. One of these is of a dark brown colour, and much shorter and thicker in proportion than the other, which grows to an immense length, an is generally of a pale greenish yellow. Throughout the Atbara, crocodiles are extremely mischievous and bold; this can be accounted for by the constant presence of Arabs and their flocks, which the crocodiles have ceased to fear, as they exact a heavy tribute in their frequent passages of the river. The Arabs assert that the dark-coloured, thick-bodied species is more to be dreaded than the other.
The common belief that the scales of the crocodile will stop a bullet is very erroneous. If a rifle is loaded with the moderate charge of two and a half drachms it will throw an ounce ball through the scales of the hardest portion of the back; but were the scales struck obliquely, the bullet might possibly glance from the surface, as in like manner it would ricochet from the surface of water. The crocodile is so difficult to kill outright, that people are apt to imagine that the scales have resisted their bullets. The only shots that will produce instant death are those that strike the brain or the spine through the neck. A shot through the shoulder is fatal; but as the body immediately sinks, and does not reappear upon the surface until the gases have distended the carcase, the game is generally carried away by the stream before it has had time to float. The body of a crocodile requires from twelve to eighteen hours before it will rise to the surface, while that of the hippopotamus will never remain longer than two hours beneath the water, and will generally rise in an hour and a half after death. This difference in time depends upon the depth and temperature; in deep holes of the river of from thirty to fifty feet, the water is much cooler near the bottom, thus the gas is not generated in the body so quickly as in shallow and warmer water. The crocodile is not a grass-feeder, therefore the stomach is comparatively small, and the contents do not generate the amount of gas that so quickly distends the huge stomach of the hippopotamus; thus the body of the former requires a longer period before it will rise to the surface.
In the evening we crossed with our baggage and people to the opposite side of the river, and pitched our tents at the village of Goorashee. A small watercourse had brought down a large quantity of black sand. Thinking it probable that gold might exist in the same locality, I washed some earth in a copper basin, and quickly discovered a few specks of the precious metal.
Gold is found in small quantities in the sand of the Atbara; at Fazogle, on the Blue Nile, there are mines of this metal worked by the Egyptian Govermnent. From my subsequent experience I have no doubt that valuable minerals exist in large quantities throughout the lofty chain of Abyssinian mountains from which these rivers derive their sources.
The camels arrived, and once more we were ready to start. Our factotum, El Baggar, had collected a number of both baggage-camels and riding dromedaries or "hygeens;" the latter he had brought for approval, as we had suffered much from the extreme roughness of our late camels. There is the same difference between a good hygeen or dromedary and a baggage-camel as between the thoroughbred and the cart-horse; and it appears absurd in the eyes of the Arabs that a man of any position should ride a baggage-camel. Apart from all ideas of etiquette, the motion of the latter animal is quite sufficient warning. Of all species of fatigue, the back-breaking monotonous swing of a heavy camel is the worst; and, should the rider lose patience, and administer a sharp cut with the coorbatch that induces the creature to break into a trot, the torture of the rack is a pleasant tickling compared to the sensation of having your spine driven by a sledge-hammer from below, half a foot deeper into the skull. The human frame may be inured to almost anything; thus the Arabs, who have always been accustomed to this kind of exercise, hardly feel the motion, and the portion of the body most subject to pain in riding a rough camel upon two bare pieces of wood for a saddle, becomes naturally adapted for such rough service, as monkeys become hardened from constantly sitting upon rough substances. The children commence almost as soon as they are born, as they must accompany their mothers in their annual migrations; and no sooner can the young Arab sit astride and hold on, than he is placed behind his father's saddle, to which he clings, while he bumps upon the bare back of the jolting camel.
