On November 23, 1876, representatives from Harvard, Yale, Princeton, and Columbia met at the Massasoit House in Springfield, Massachusetts to standardize a new code of rules based on the rugby game first introduced to Harvard by McGill University in 1874. Three of the schools—Harvard, Columbia, and Princeton—formed the Intercollegiate Football Association, as a result of the meeting. Yale initially refused to join this association because of a disagreement over the number of players to be allowed per team (relenting in 1879) and Rutgers were not invited to the meeting. The rules that they agreed upon were essentially those of rugby union at the time with the exception that points be awarded for scoring a try , not just the conversion afterwards ( extra point ). Incidentally, rugby was to make a similar change to its scoring system 10 years later.
