As the power is gradually turned on, the heavyshaft begins slowly to revolve. The separate clicking of thehammers can be heard distinctly at first, but as the shaftgathers way, these sounds are blended into one confused roar,the note of which gradually rises until the power is fully turnedon and full speed attained, when the sound be<strong>com</strong>es a steadydeafening note of extremely high pitch.When the first handfuls of paper are thrown into the jawsof the machine the visitor is usually somewhat startled by theloud report which follows, and by the rapidity with which theleaves break into a miniature snowstorm.
