The straitened figure of the bivouac rendered it impossible to make arrangements with much regularity in view to defence. The horses were picketted in the centre of the ravine. The European escort occupied a position betwixt them and the northern side, and the scanty beds of the officers of the party were spread close to the southern bank. A strong picket of the Danakil was placed a little distance in advance; and, in addition to the numerous other native guards in various quarters, the usual precaution was observed of mounting a European sentry, whose beat extended the length of the front of the encampment. Old Izhak slept close to the beds of the embassy, and, evidently in a state of considerable trepidation, solaced himself until a late hour by recounting bloody tales of murder and assassination, perpetrated, within his knowledge, by the mountain _Buddoos_ haunting the ravine of Goongoonteh, which, being the high road to the Salt Lake, forms the resort of numerous evil disposed ruffians, who are ever on the prowl to cut throats, and to do mischief. The first night, although awfully oppressive from the heat exhaled from the baked ground, and the absence of even the smallest zephyr, passed quietly enough; and after another grilling day, which seemed to have no termination, spent within the caverns, the same nocturnal arrangement as before was observed with undiminished precaution. An hour before midnight a sudden and violent sirocco scoured the wady, the shower of dust and pebbles raised by its hot blast, being followed by a few heavy drops of rain, with a calm, still as the sleep of death. The moon rose shortly afterwards, and about two o'clock a wild Irish yell, which startled the whole party from their fitful slumbers, was followed by a rush of men, and a clatter of hoofs, towards the beds of the Embassy. Every man sprang instinctively on his feet, seized a gun, of which two or three lay loaded beside each, and standing on his pillow with weapon cocked, prepared for the reception of the unseen assailants. Fortunate was it that no luckless savage, whether friend or foe, followed in the disorderly retreat, or consequences the most appalling must inevitably have ensued; but the white legs of half-naked and unarmed artillerymen having passed at speed, were followed only by a crush of horses and mules that had burst from their pickets. So complete was the panic caused by a sudden start from deep sleep to witness the realisation of the murderous tales of midnight assassination which had been poured into their ears, that the flying soldiery, who in the battle field had seen comrades fell thick around them, and witnessed death in a thousand terrific forms, were rallied with difficulty. But a panic is of short duration if officers perform their duty, and the word "Halt!" acted like magic upon the bewildered senses of the survivors, who, falling in, formed line behind the rifles.
