So far no signs of the presence of hostile natives had been perceived. The usual precautions, however, had been taken; the cargoes had all been carried up by hand and deposited so as to form a breastwork, and as night closed in several sentries were placed to guard against surprise. It had been arranged that the men belonging to the boats each day brought up should that night take sentinel duty; and this evening Jethro, his companions and boatmen were among those on guard. Many of the boats had left Semneh before them, and they had been among the last to arrive at the foot of the cataracts, and consequently came up in the last batch. As owners they had been exempt from the labors of dragging up the boats, and had spent much of their time during the enforced delay in hunting. They had obtained dogs and guides from the village at the foot of the cataracts and had had good sport among the ibex which abounded in the rocky hills. The girls had seldom left their cabin after leaving Semneh. There was nothing remarkable in the presence of women in a boat going so far up the river, as many of the traders took their wives on their journeys with them. When, however, they journeyed beyond Semneh they left them there until their return, the danger and hardships of the desert journey being too great for them to encounter, and it was therefore thought advisable that the girls should remain in seclusion. Jethro, Amuba, and Chebron were standing together at one of the angles of the encampment when the former suddenly exclaimed: “There are men or animals moving on that steep hill opposite! I thought several times I heard the sound of stones being displaced. I certainly heard them then.” Then turning round he raised his voice: “I can hear sounds on the hill. It were best that all stood to their arms and prepare to resist an attack.” In an instant the sound of song and laughter ceased amid the groups assembled round the fires and each man seized his arms. There was a sharp ringing sound close to Jethro, and stooping he picked up an arrow which had fallen close to him. “It is an enemy!” he shouted. “Draw up close to the breastwork and prepare to receive them. Scatter the fires at once and extinguish the blazing brands. They can see us, while themselves invisible.” As he spoke a loud and terrible yell rose from the hillside and a shower of arrows was poured into the encampment. Several men fell, but Jethro’s orders were carried out and the fires promptly extinguished. “Stoop down behind the breastwork,” Jethro shouted, “until they are near enough for you to take aim. Have your spears ready to check their onslaught when they charge.”
