As a result of this, Harvard refused to attend the rules conference organized by Rutgers, Princeton and Columbia at the Fifth Avenue Hotel in New York City on October 20, 1873 to agree on a set of rules and regulations that would allow them to play a form of football that was essentially Association football; and continued to play under its own code. While Harvard's voluntary absence from the meeting made it hard for them to schedule games against other American universities, it agreed to a challenge to play the rugby team of McGill University, from Montreal, in a two-game series. It was agreed that two games would be played on Harvard's Jarvis baseball field in Cambridge, Massachusetts on May 14 and 15, 1874: one to be played under Harvard rules, another under the stricter rugby regulations of McGill. Jarvis Field was at the time a patch of land at the northern point of the Harvard campus, bordered by Everett and Jarvis Streets to the north and south, and Oxford Street and Massachusetts Avenue to the east and west. Harvard beat McGill in the "Boston Game" on the Thursday and held McGill to a 0–0 tie on the Friday. The Harvard students took to the rugby rules and adopted them as their own, The games featured a round ball instead of a rugby-style oblong ball. This series of games represents an important milestone in the development of the modern game of American football. In October 1874, the Harvard team once again traveled to Montreal to play McGill in rugby, where they won by three tries.
