Final plans as announced yesterday set the opening of the Model constitutional Convention in which seventy Harvard Undergraduates are partaking for tomorrow afternoon at Phillips Brooks House at 1:30 o'clock.

The remaining sessions of the Convention will be held in Sever 11, late on Friday afternoon and all day Saturday. The Convention has been organized into six committees which will deliver their respective reports to the entire Convention tomorrow afternoon with recommendations on philosophical interpretation and methods of constitutional amendment. The other reports will be delivered later on in the day and discussion and final action taken Saturday.

Among the faculty members co-operating will be Arthur N. Holcombe '06, professor of Government, who has termed the Convention as something that "should help clarify public thinking on this fundamental topic."
