Published as a 50-page book, the story tells of the invention of the Prospective Telegraph
and provides excerpts from a newspaper that it retrieves from a 1977 future dominated by
scientific and medical super-nannies.
— Michael Main
By this truly wonderful invention (exquisitely simple in its machinery, yet of surpassing
power) the obstacle of Time is as effectually conquered as that of Space has been for the
last generation by the Electric Telegraph; and future years—even, it is anticipated,
future centuries—will be made to respond to our call as promptly and completely as do
now the uttermost parts of the earth wherewith the magic wire has placed us in
communication.
