Peering through a narrow gap between the large lumps of coal, Peter made the discovery that the tow-path against which the barge lay was clear, and apparently right out in the country and free from the presence of buildings. The fact puzzled him. Why on two consecutive nights the barge should choose a berth far from a town or village required a lot of explanation. He could only suggest that the women manning the boat took care to avoid Populous districts, so that they could go ashore without exposing the cargo to the predatory activities of the war-tried inhabitants.
