THE 'Contrast' was the first American play ever performed in public by a company of professional actors. Several plays by native authors had been previously published, the more noteworthy being the 'Prince of Parthia,' a tragedy by Thomas Godfrey of Philadelphia, which was probably written, and was offered to Hallam's company in 1759 (but not pro- duced), and was printed in 1765, two years after the author's death.
