[44] Curtis Nettels says of the Stamp Act opposition, "The most telling
weapons used by the colonists were the non-importation agreements, which
struck the British merchants at a time when trade was bad." _The Roots
of American Civilization_ (New York: Crofts, 1938), 632. Later he says,
"The colonial merchants again resorted to the non-importation agreements
as the most effectual means of compelling Britain to repeal the
Townshend Acts." _Ibid._, 635.
