act to regulate practice in the courts of law in that colony became known as " Clark's law," and a strong spirit of enmity was manifested by the members of the bar against the supposed framer of it. Although opposed to the emission of debased money, he was styled the " Father of the Paper Currency " on account of his presumed influence being given toward the introduction of such a measure. He was a delegate to the convention that framed the Federal constitution in 1787, and in 1789 was appointed a commissioner to settle the accounts of New Jersey with the United States. Later he became a member of congress, serving from 24 Oct., 1791, till his death. During his con- gressional career he participated in the debates concerning the relations of England with the United States, and moved a resolution to prohibit all intercourse with Great Britain until full com- pensation was made to our citizens for the injuries sustained by them from British armed vessels, and until the western posts should be delivered up. A bill conforming to Mr. Clark's resolution was car- ried by a considerable majority in the house, but was lost in the senate by the casting vote of John Adams, the vice-president. His death was the re- sult of a sunstroke, which proved fatal in two hours.
