Plug up the Hudson river at both ends of Manhattan . . . divert that body of water into the Harlem river so that it might flow out into the East river and down to the Atlantic ocean . . . pump out the water from the area of the Hudson which has been dammed off … fill in that space . . . ultimately connecting the Island of Manhattan with the mainland of New Jersey . . . and you have the world’s eighth wonder- the reconstruction of Manhattan!

That is the essence of the plan proposed by Norman Sper, noted publicist and engineering scholar. It is calculated to solve New York City’s traffic and housing problems, which are threatening to devour the city’s civilization like a Frankenstein monster.
