Accordingly a fresh American Taxation Act was passed in 1767, imposing import duties on tea, glass, and other articles, the object being to assert the right of taxing the colonies. It was, however, found impossible to collect the new duties. The people of Boston, Massachusetts, were conspicuous for their violence in resisting this new and vexatious impost, at the same time proposing a strict union of all the local assemblies in British America to oppose the law and to insist on its repeal. Troops were sent to enforce allegiance to the authorities. The Boston merchants and shipowners, however, were resolute in their action, and the seizure of a sloop belonging to one of their citizens causing much excitement, they passed a further resolution of non-intercourse, at one of their numerous meetings, unless the last obnoxious Act was repealed. The inhabitants of New York carried similar resolutions. In this unsatisfactory way matters continued till 1770, when the Act was repealed in all articles except tea. The people of America had, however, begun to feel still more their strength, and declared any such reservation to be inadmissible. In 1774, when vessels having this article on board reached Boston, the people seized the tea, threw some portion of it overboard, and destroyed the remainder, suspending all business of landing and shipping goods in Boston harbour after the 1st June, 1774, and declaring all charter-parties, bills of lading, and contracts executed in England for shipping goods from that port null and void.
