366 SUNDRY HINTS. [CHAP. XXI. proof both against insects and weather, and can be towed with their contents across a river. Travelling is now so generally understood, that it is hardly necessary to give any instructions for the exploration of wild countries; but a few hints may be acceptable upon points that, although not absolutely essential, tend much to the comfort of the traveller. A couple of large carriage umbrellas with double lining, with small rings fixed to the extremities of the ribs, and a spike similar to that of a fishing-rod to screw into the handle, will form an instantaneous shelter from sun or rain during a halt on the march, as a few strings from the rings will secure it from the wind, if pegged to the ground. Waterproof calico sheeting should be taken in large quantities, and a tarpaulin to protect the baggage during the night's bivouac. No vulcanised India-rubber should be employed in tropical climates; it rots, and becomes useless. A quart syringe for injecting brine into fresh meat is very necessary. In hot climates, the centre of the joint will decompose before the salt can penetrate to the interior, but an injecting syringe will thoroughly preserve the meat in a few minutes. A few powerful fox-traps are useful for catching night-game in countries where there is no large game for the rifle also wire is useful for making springs. Several sticks of Indian-ink are convenient, as sufficient can be rubbed up in a few moments to write up the notebook during the march. All journals and note-books should be of tinted paper, green, as the glare of white paper in the intense sunlight of the open sky is most trying to the eyes. Burning glasses and flint and steels are very necessary. Lucifer matches are dangerous, as they may ignite and destroy your baggage in dry weather, and become utterly useless in the damp. A large supply of quicksilver should be taken for the admixture with lead for hardening bullets, in addition to that required for the artificial horizon; the effect of this metal is far greater than a mixture of tin, as the specific gravity of the bullet is increased. Throughout a long experience in wild sports, although I admire the velocity of conical projectiles, I always have CHAP. XXI.] CHOICE OF BULLETS. 367 retained my opinion that, in jungle countries, where in the absence of dogs you require either to disable your game on the spot, or to produce a distinct blood-track that is easily followed, the old-fashioned two-groove belted ball will bag more game than modern bullets; but, on the other hand, the facility of loading a conical bullet already formed into a cartridge is a great advantage. The shock produced by a pointed projectile is nothing compared to that of the old belted ball, unless it is on the principle of Purday's high velocity expanding bullet, which, although perfection for deer-shooting, would be useless against thick-skinned animals, such as buffalo and rhinoceros. In Africa, the variety of game is such, that it is impossible to tell, when loading, at what animal the bullet will be fired; therefore, it is necessary to be armed with a rifle suitable for all comers. My little Fletcher was the Enfield bore, No. 24, and, although a most trusty weapon, the bullets generally failed to penetrate the skull of hippopotami, except in places where the bone was thin, such as behind the ear, and beneath the eyes. Although I killed great numbers of animals with the Enfield bullet, the success was due to tolerably correct shooting, as I generally lost the larger antelopes if wounded by that projectile in any place but the neck, head, or shoulder; the wound did not bleed freely, therefore it was next to impossible to follow up the blood-track; thus a large proportion of wounded animals escaped. I saw, and shot, thirteen varieties of antelopes while in Africa. Upon arrival at Khartoum, I met Herr von Heuglin, who commanded the expedition in search of Dr. Vogel; he was an industrious naturalist, who had been many years in the Soudan and in Abyssinia. We compared notes of all we had seen and done, and he very kindly supplied me with a list of all the antelopes that he had been able to trace as existing in Abyssinia and the Soudan; he now included my maarif, which he had never met with, and which he agreed was a new species. In the following list, which is an exact copy of that which he had arranged, those marked with an asterisk are species that I have myself shot:: 368 ANTELOPES OF CENTRAL AFRICA [CHAP.

FOR Some days we continued our journey along the banks of the Dinder, and as the monotonous river turned towards the junction with the Blue Nile, a few miles distant, we made a direct cut across the flat country, to cross the Rahad and arrive at Abou Harraz on the Blue Nile. We passed numerous villages and extensive plantations of dhurra that were deserted by the Arabs, as the soldiers had arrived to collect the taxes. I measured the depths of the wells, seventy-five feet and a half, from the surface to the bottom; the alluvial soil appeared to continue the whole distance, until the water was discovered resting upon hard sand, full of small particles of mica. During the march over a portion of the country that had been cleared by burning, we met a remarkably curious hunting-party. A number of the common black and white stork were hunting for grasshoppers and other insects, but mounted upon the back of each stork was a large copper-coloured flycatcher, which, perched like a rider on his horse, kept a bright look-out for insects, which from its elevated position it could easily discover upon the ground. I watched them for some time: whenever the storks perceived a grasshopper or other winged insect, they chased it on foot, but if they missed their game, the flycatchers darted from their backs and flew after the insects like falcons, catching them in their beaks, and then returning to their steeds to look out for another opportunity. On the evening of the 23d May we arrived at the Rahad close to its junction with the Blue Nile: it was still dry, although the Dinder was rising. I accounted for this, from the fact of the extreme length of the Rahad's bed, which, from its extraordinary tortuous course, must absorb a vast amount of water in the dry sand, before the |
