He reflected on the peculiarities and position of the wall before him. Although the widest and most important of the rents which he had observed in it, existed too near the rampart to be reached without the assistance of a ladder, there were others as low as the ground, which he knew, by the result of the trial he had already made, might be successfully and immensely widened by the most ordinary exertion and perseverance. The interior of the wall, if judged by the condition of the surface, could offer no insuperable obstacles to an attempt at penetration so partial as to be limited to a height and width of a few feet. The ramparts, from their position between two guard-houses, would be unencumbered by an inquisitive populace. The sentinel, within the limits of whose allotted watch it happened to fall, would, when night came on, be the only human being likely to pass the spot; and at such an hour his attention must necessarily be fixed--in the circumstances under which the city was now placed--on the prospect beyond, rather than on the ground below and behind him. It seemed, therefore, almost a matter of certainty, that a cautious man, labouring under cover of the night, might pursue whatever investigations he pleased at the base of the wall. He examined the ground where he now stood. Nothing could be more lonely than its present appearance. The private gardens on the hill above it shut out all communication from that quarter. It could only be approached by the foot-path that ran round the Pincian Mount, and along the base of the walls. In the state of affairs now existing in the city, it was not probable that any one would seek this solitary place, whence nothing could be seen, and where little could be heard, in preference to mixing with the spirit-stirring confusion in the streets, or observing the Gothic encampment from such positions on the ramparts as were easily attainable to all. In addition to the secresy offered by the loneliness of this patch of ground to whatever employments were undertaken on it, was the further advantage afforded by the trees and thickets which covered its lower end, and which would effectually screen an intruder, during the darkness of night, from the most penetrating observation directed from the wall above.
