Having at length gained possession of many places, and most of them without loss to his army, he turned his thoughts to another enterprise, which, though not of the same desperate character as that at Capsa, was yet not less difficult of execution.[268] Not far from the river Mulucha, which divided the kingdoms of Jugurtha and Bocchus, there stood, in the midst of a plain,[269] a rocky hill, sufficiently broad at the top for a small fort; it rose to a vast height, and had but one narrow ascent left open, the whole of it being as steep by nature as it could have been rendered by labor and art. This place, as there were treasures of the king in it, Marius directed his utmost efforts to take.[270] But his views were furthered more by fortune than by his own contrivance. In the fortress there were plenty of men and arms for its defense, as well as an abundant store of provisions, and a spring of water; while its situation was unfavorable for raising mounds, towers, and other works; and the road to it, used by its inhabitants, was extremely steep, with a precipice on either side. The vineae were brought up with great danger, and without effect; for, before they were advanced any considerable distance, they were destroyed with fire or stones. And from the difficulties of the ground, the soldiers could neither stand in front of the works, nor act among the vineae,[271] without danger; the boldest of them were killed or wounded, and the fear of the rest increased. XCIII. Marius having thus wasted much time and labor, began seriously to consider whether he should abandon the attempt as impracticable, or wait for the aid of Fortune, whom he had so often found favorable. While he was revolving the matter in his mind, during several days and nights, in a state of much doubt and perplexity, it happened that a certain Ligurian, a private soldier in the auxiliary cohorts,[272] having gone out of the camp to fetch water, observed, near that part of the fort which was furthest from the besiegers, some snails crawling among the rocks, of which, when he had picked up one or two, and afterward more, he gradually proceeded, in his eagerness for collecting them, almost to the top of the hill. When he found this part deserted, a desire, incident to the human mind, of seeing what he had never seen,[273] took violent possession of him. A large oak chanced to grow out among the rocks, at first, for a short distance, horizontally,[274] and then, as nature directs all vegetables,[275] turning and shooting upward. Raising himself sometimes on the boughs of this tree, and sometimes on the projecting rocks, the Ligurian, as all the Numidians were intently watching the besiegers, took a full survey of the platform of the fortress. Having observed whatever he thought it would afterward prove useful to know, he descended the same way, not unobservantly, as he had gone up, but exploring and noticing all the peculiarities of the path. He then hastened to Marius,
