To control pedestrians better, the school is giving the Senior Fence an ell shape this month by moving part of it to the south end of the Green, on the same corner, as a press release explains.   The original part of the fence dates to the turn of the century (the original, practical 1836 fence came down in 1893).   In 1899, students suggested that a second fence for sitting on should occupy the west side of the Green, indicating dissatisfaction with the slightly earlier Senior Fence on the north half of the east side of the Green (“Such a [new] fence would not detract from the value of the senior fence which has never met purpose for which it was designed,” The Dartmouth [20 April 28, 1899]: 449) and a view of ca. 1914 shows the current replacement, a double row of fences south of the middle of the west side of the Green.   Plaques indicate that donors later extended that fence southward to give it its present form.
