No man ever doubted that the commodity of tea could bear an imposition
of threepence. But no commodity will bear threepence, or will bear a
penny, when the general feelings of men are irritated, and two millions
of people are resolved not to pay. The feelings of the colonies were
formerly the feelings of Great Britain. Theirs were formerly the
feelings of Mr. Hampden when called upon for the payment of twenty
shillings. Would twenty shillings have ruined Mr. Hampden's fortune? No!
but the payment of half twenty shillings, on the principle it was
demanded, would have made him a slave.
