Pan Andrew fitted his key to the lock of the door leading into the inner room and threw back the bolt. Entering after his father, Joseph found himself in a small, comfortable room, containing a table, a bed, a small stove, and a lighted lantern hanging on the wall. About the table were three chairs, wedged rather tightly because of the lack of space, and upon the table was a huge hourglass, one of the largest that Joseph had even seen. The sand pouring through it in a fine stream had filled the lower section almost to a level graded on the glass with a Latin “X” to designate the tenth hour. The glass was in reality a twelve-hour glass, and lines and Latin numerals had been marked upon it just after the maker had blown it into shape, when the material was still soft. This was the trumpeter’s official clock. There was on the south side of the nave roof, where the sun touched at all hours of the day, a large sundial which was read each noon, and on the north wall of the tower was a clock with one hand. This hand, which indicated the hours, was in truth a hand—a piece of metal shaped like a doubled fist—with fingers curled and the index pointing out to the hours. When the sand had reached the level of the glass at which the “X” was cut, Pan Andrew hastened out to the open section of the tower and released a coil of rope that hung on a pillar in the center of the space. This rope ran down through a hole in the flooring until it reached the level of the lower tower, when it swung about over a piece of round wood that served as a pulley and leaped from there to the lower tower through an aperture that was originally designed as a narrow window through which to shoot arrows in time of defense. In the lower tower the rope was connected with one end of an iron hammer that was suspended above the great bell. When the rope was pulled the hammer descended, but it sprang quickly back to its original position when the rope was loosed, a spring of twisted metal and leather serving to draw it back. Pan Andrew pulled once—the hammer descended—boom—the stroke of the bell sounded over the whole city. He pulled again and again until the full quota of ten strokes was made.
