Freshman Frolic
Begun informally around the turn of the century, Freshman Frolic became an established, and regulated, tradition within ten years and was extinct within twenty. The rules of Freshman Frolic as stated in the 1913 handbook were:

1. Permission must be obtained from the Dean
2. Two thirds of the class and all officers must be present.
3. Refreshments must be served
4. The Freshmen must yell "19-Freshman Frolic"
5. The presence of one sophomore loses the frolic for the freshmen.

A student complained in a 1912 editorial that "we are about to reduce [Freshman Frolic] to rules and regulations, so that we may know who won. Can't we see that a frolic, ruled and regulated, is a contradiction of terms? that the object of it all is not to win, but to have a frolic?"

Freshman Mountain Day Also known as "Freshman Stunt Day", Freshman Mountain Day dates back at least to before the 1890s and was usually held in early June. Henrietta Hooker describes it:

"In accordance with an old custom, in early spring the youngest class are allowed 'Freshman Day', to pay their respects to Mount Holyoke; and no happier hour comes into college life than this, when, with a year of completed work almost behind them, they ride away under the apple-blossoms, through 'the long, low, lazy hamlet Hockanum', to the commanding height from which the college takes its name."

Freshman Mountain Day continued even after the Mountain Day celebrations were moved to the autumn, until the individual class Mountain Day celebrations became an all-college celebration.
