SPOOKER, n.  A writer whose imagination concerns itself with
supernatural phenomena, especially in the doings of spooks.  One of
the most illustrious spookers of our time is Mr. William D. Howells,
who introduces a well-credentialed reader to as respectable and
mannerly a company of spooks as one could wish to meet.  To the terror
that invests the chairman of a district school board, the Howells
ghost adds something of the mystery enveloping a farmer from another
township.
