Note 170 — 172. Abigail Adams.
Reading edition
A man used to ride on an ass, with immense jack boots and his face covered with a horrible mask, and was called Joice junior. His office was to assemble men and boys in mob style, and ride, in the middle of them, to terrify the adherents to the royal government.—Niles's Principles and Acts of the Revolution, p. 490.
