by a dozen pair of eyes. For all he knew every man in that room might be facing his way. He had expected to hear the noise of machinery, but beyond the strangled voices, occasionally the click of glass against glass and the shuff-shuff-shuff of slippered feet crossing the floor, he heard nothing.
He pulled the door another quarter of an inch and glued his eye to the crack. At this angle he could only see one of the walls of the big vault and the end of a long vapour-lamp which stood in one of the cornices and which supplied the ghastly light. But presently he saw something which filled him with hope. Against the wall was a high shadow which even the overhead lamp did not wholly neutralize. It was an irregular shadow such as a stack of boxes might make, and it occurred to him that perhaps beyond his range of vision there was a barricade of empty cases which hid the door from the rest of the room.
He spent nearly three-quarters of an hour taking a bearing based upon the problematical position of the lights, the height and density of the box screen and then boldly and rapidly opened the door, stepped through and closed it behind him. His calculations had been accurate. He found himself in a room, the extent of which he could only conjecture. What, however, interested him mostly was the accuracy of his calculation that the door was hidden. An "L"-shaped stack of crates was piled within two feet of the ceiling, and formed a little lobby to anybody entering the vault the way Beale had come. They were stacked neatly and methodically, and with the exception of two larger packing-cases which formed the "corner stone" the barrier was made of a large number of small boxes about ten inches square.
There was a small step-ladder, evidently used by the person whose business it was to keep this stack in order. Beale lifted it noiselessly, planted it against the corner and mounted cautiously.
He saw a large, broad chamber, its groined roof supported by six squat stone pillars. Light came not only from mercurial lamps affixed to the ceiling, but from others
