In the middle of the room was a rude sort of keyboard, with pedals below, like those of a large organ. Fronting this construction sat a long, high-backed bench. On the rack over the keyboard rested some sheets of music, which, upon examination, I found to be of parchment and written by hand. The notes were curious in shape, consisting of squares of black and diamonds of red upon the lines. Across the top of the page was written, in a straggling hand, "Van den Gheyn Nikolaas." I turned to the little old man with the ruffles. "Van den Gheyn!" I said in surprise, pointing to the parchment. "Why, that is the name of the most celebrated of _carillonneurs_, Van den Gheyn of Louvain." He untwisted his hands and bowed. "Eet ees ma name, mynheer--I am the _carillonneur_." I fancied that my face showed all too plainly the incredulity I felt, for his darkened, and he muttered, "You not belief, Engelsch? Ah, I show you; then you belief, parehap," and with astounding agility seated himself upon the bench before the clavecin, turned up the ruffles at his wrists, and literally threw himself upon the keys. A sound of thunder accompanied by a vivid flash of lightning filled the air, even as the first notes of the bells reached my ears. Involuntarily I glanced out of the diamond-leaded window--dark clouds were all about us, the housetops and surrounding country were no longer to be seen. A blinding flash of lightning seemed to fill the room; the arms and legs of the little old man sought the keys and pedals with inconceivable rapidity; the music crashed about us with a deafening din, to the accompaniment of the thunder, which seemed to sound in unison with the boom of the bourdon. It was grandly terrible. The face of the little old man was turned upon me, but his eyes were closed. He seemed to find the pedals intuitively, and at every peal of thunder, which shook the tower to its foundations, he would open his mouth, a toothless cavern, and shout aloud. I could not hear the sounds for the crashing of the bells. Finally, with a last deafening crash of iron rods and thunderbolts, the noise of the bells gradually died away. Instinctively I had glanced above when the crash came, half expecting to see the roof torn off. "I think we had better go down," I said. "This tower has been struck by lightning several times, and I imagine that discretion--"
