The entire undergraduate body will vote Thursday on a proposal to lengthen the much-discussed midyear recess, the Student Council announced last night.

Students will reply to four questions asking whether they wish a longer midyear or Thanksgiving recess, or both, and will indicate their choice of two possible calendar revisions.

Council president Edward M. Abramson '57 said last night in reference to the calendar change that "so far we have received nothing but encouraging words about our project from students, faculty, and administration. I only hope that continued student enthusiasm... will remain manifest in a large return on our poll, which will enable us to endorse our plan with the firm conviction of the student body.

"The project was originally undertaken in response to continued dissatisfaction among the student body, culminating this year with numerous complaints and a CRIMSON editorial on the subject," Abramson added.

The ballots will also ask the students who indicated a preference for longer mid-year vacations whether they would be willing to start school a week earlier in the fall, as well as having days pared from the spring reading period.

The poll is the work of a three-man Council calendar revisions committee headed by Charles O. Chambers, Jr. '58.

Prior to February 1952 the University calendar provided for one more day between terms, but the day was cut in making the academic year a week shorter.
