The fires were blazing after sunset; the horses of my Hamran hunters, and my own, were picqueted within the centre of our enclosure, near the tent, and we were about to retire for the night, when a deep guttural sigh was heard close to the high and impervious fence of kittur thorns. This had been carefully constructed, as life was most uncertain within that questionable district, where the Arab hunting parties invariably killed all natives of the crafty Base tribe whenever met, and they incurred a similar retaliation. The fence was made of entire trees cut off near the roots, and then dragged by the stems into line, with their wide-spreading heads of sharp hooked thorns forming the outside surface; these were locked together by their hooks, entangled, and nothing could possibly have broken through, except an elephant or rhinoceros. Prowling around this excellent protection was a lion, who was pronounced by my hunters to be the mate of the lioness which I had killed; it was declared that the disconsolate husband had followed the course of his wife's body, denoted by the drops of blood that had dripped upon the ground when carried by the camel towards the camp. My people were of opinion that the lion was determined upon vengeance, and that he would assuredly bound over our fence, although he could not absolutely break through it. The night was always interesting upon the banks of the Settite river, as vast numbers of wild animals were astir half an hour after sunset, which either came down to drink, or to wander in search of green pasturage, that was only to be found in places from which the water had retreated. The lions were accordingly on the alert, and the threatening sound of their deep voices was to be heard in every direction, until approaching daylight drove them to their thickets. There is nothing so beautiful, or enjoyable to my ears, as the roar of a lion upon a still night, when everything is calm, and no sound disturbs the solitude except the awe-inspiring notes, like the rumble of distant thunder, as they die away into the deepest bass. The first few notes somewhat resemble the bellow of a bull; these are repeated in slow succession four or five times, after which the voice is sunk into a lower key, and a number of quick short roars are at length followed by rapid coughing notes, so deep and powerful that they seem to vibrate through the earth. Our nocturnal visitor did not indulge in the usual solo, but he continued throughout the night to patrol the circuit of the camp, occasionally betraying his presence by a guttural roar, or by the well- known deep sigh which exhibited the capacity of his lungs. We could not see to shoot, owing to the darkness outside the fence, and the brightness of our fire within the camp; this my men industriously replenished with wood, and occasionally hurled fire-brands in the direction of the intruder.
