Daniel picked up the glass, telescoped it to full length, and set its wide end into the vee of the missing diamond, which had thoughtfully been lined with a rag. This held it perfectly steady, while allowing him to swivel the narrow end to and fro. Putting his eye to it, and making some small adjustments, he was rewarded with a magnified view of some windows on the upper storey of the Tatler-Lock. Several were boarded over, or else veiled with remnants of sails. One was but a vacant window-frame. Through this could be seen the floor-boards of an empty room, starry with bird-shit.
