BREAKING THE GREAT TABOO At the threshold of that quarter of old New York called Greenwich Village stands Jefferson Market Court.

Almost concealed behind the towering structure of the Sixth Avenue Elevated, the building by day is rather inconspicuous.

High up in the square brick tower an illuminated clock seems perpetually to be hurrying its pointing hands toward midnight.

From many windows, barred for the most part, streams an intense white light.
