Round-heads.

1781.  Newhaven is celebrated for having given the name of pumkin-heads to all the New-Englanders. It originated from the Blue Laws, which enjoin every male to have his hair cut round by a cap. When caps were not to be had, they substituted the hard shell of a pumkin, which being put on the head every Saturday, the hair is cut by the shell all round the head.—Samuel Peters, ‘History of Connecticut,’ p. 195 (Lond.). (N.E.D.) (Italics in the original.)
