The interior of this large compartment of the air cruiser may have been originally designed for carrying freight. Bill now found that the remodeled hold served quite another purpose. At right angles to the entrance, a narrow corridor ran lengthwise down the middle of the cabin. Opening off this were tiny wooden cubicles with just enough space behind their barred doors for a man to sit on the narrow bench which served as the sole article of furniture in each tiny cell. The place reminded Bill of the eighteenth century prison hulks about which he had read. Light and air were let in through iron barred portholes and Bill was glad to find that the cell that housed him contained one of these small windows. By squeezing sideways on his seat, he got a restricted view of the bay.
