Architecturally attached to Peterhouse is, as has been said, the church of St. Mary "the less," so called in contradistinction to "Great" St. Mary's, which here, as at Oxford, is the designation of the "University Church." This is the only really beautiful church in Cambridge, the tracery of the windows being exquisite flowing Decorated. All date from the fourteenth century, when the present structure displaced the earlier church dedicated to St. Peter. One feature of interest here is a monument put up to Richard Washington, who was minister of this church in the beginning of the eighteenth century. He was of the same family as the great George Washington, and in the coat of arms here displayed we may see the origin of the American Stars and Stripes, while the crest has become the American eagle.[7] [Footnote 7: The Washington arms are, in heraldic language: Barry of four, gules and argent. On a chief azure three mullets of the second. Crest, a demi-eaglet sable rising from an earl's coronet.] To the west of the church we get a view of the back of Peterhouse in its untouched picturesqueness, abutting on the churchyard, at the end of which comes another Museum, that of Classical Archaeology. This is reached by a narrow lane, having the church on one side, and on the other "Emmanuel," the leading Congregationalist place of worship in Cambridge. As we return between these into the street we should look up at the buildings of Peterhouse and notice, in front of the window at the top corner of the ivy-clad wall, an erection of stout iron bars. By these hangs a tale; for the window belongs to the rooms traditionally occupied by the poet Gray when in residence here. It is said that he caused these bars to be put up, from his constitutional dread of fire, and that he kept a stout rope constantly affixed to them as a means of escape in case of need. Awakened one night by shouts of "Fire! Fire!" he slid down this rope in deshabille--to find himself plunged at the bottom into a huge vat of water placed there by his friends. So runs the tale; which adds that Gray migrated in disgust from Peterhouse to Pembroke. That he did so migrate is quite historical. To reach his new College, Gray had only to cross the street; for almost immediately opposite to Peterhouse are seen the more widely extended buildings of Pembroke. Not so very many years ago they were the less widely extended of the two; for while Peterhouse has remained comparatively stationary, Pembroke, more than any other College, has partaken in the wonderful expansion which the last half century has wrought in the number of University students at Cambridge.
