deciphering a note

"Few persons can be made to believe that it is not quite an easy thing to invent a method of secret writing which shall baffle investigation.
Yet it may be roundly asserted that human ingenuity cannot concoct a cipher which human ingenuity cannot resolve..."
(Edgar Alan Poe - "A Few Words On Secret Writing", 1841)
