'COMM::eng'                                         ('The phonograph was conceived by Thomas Edison on 18 July 1877 for recording '
 'telephone messages, (not too many people needed a tele. Answering machine in '
 '1877.) his first test used waxed paper. In early production versions the '
 'recordings were done on the outside surface of a strip of tinfoil wrapped '
 'around a rotating metal cylinder. By the 1880s wax cylinders were mass '
 'marketed. These had sound recordings in the grooves on the outside of hollow '
 'cylinders of slightly soft wax. These cylinders could easily be removed and '
 'replaced on the mandrel of the machine which played them. Early cylinder '
 'records would commonly wear out after they were played a few dozen times; '
 'the buyer could then either bring the worn cylinders back to the dealer to '
 'be traded in as partial credit for purchase of new recordings, or have their '
 'surface shaved smooth so new recordings could be made on them. With an '
 'attachment, the cylinder player could record at home! In 1890 Charles '
 'Tainter patented the use of hard carnauba wax as a replacement for the '
 'common mixture of paraffin and beeswax used on phonograph cylinders.\r\n'
 '\r\n'
 'Listening to a cylinder with rubber ear-tubes; early cylinder machines of '
 'the late 1880s and the 1890s were often sold with recording attachments. The '
 'ability to record as well as play back sound was an advantage to cylinder '
 'phonographs over the competition from cheaper (Edison cylinder machines cost '
 '$80. bucks) disc record phonographs which began to be mass marketed at the '
 'end of the 1890s, as the disc system machines could be used only to play '
 'back pre-recorded sound.\r\n'
 '\r\n'
 'The earliest stages of phonograph manufacturing various competing '
 'incompatible types of cylinder recordings were made, but in the late 1880s a '
 'standard system was decided upon by Edison Records, Columbia Phonograph, and '
 'other companies; these were about 4 inches (10 cm) long, 2¼ inches in '
 'diameter, and played about two minutes of music or other sound.\r\n'
