Passing through the court, we come to the beautiful bridge, already familiar to us from the river. Its balustraded parapet is surmounted by fourteen large balls of stone, thirteen of them whole, and one out of which a cantle of nearly a quarter of its bulk has, for some unknown reason and at some unknown date, been cut. A cheap laugh may thus be obtained by challenging a stranger to count these balls accurately; for the missing cantle, being turned towards the river, is quite invisible from the bridge itself. Another feature in connection with these balls is that one of them is visibly much newer than the rest (which, like the bridge, date from the middle of the seventeenth century). This is due to a not very far off feud between Clare and St. John's, when a piratical Johnian crew came up the river after dark and stormed the bridge. Before the enraged Clare men could open the iron gate under the College archway and pour out to the rescue, the enemy had begun throwing the balls into the water, where one sank so deep into the muddy bottom that it could never be recovered. From the bridge we get a lovely view of the College "Backs." To the south the single slender arch of King's Bridge flings itself over the river in the graceful curve which is all its own; to the north we see the iron span of Garret Hostel Bridge, hiding from us the beauties of Trinity Bridge beyond. But, if there be no ripple upon the water, the three graceful arches of this invisible bridge are seen reflected upon the glassy surface with a specially charming effect. The whole view is amongst the world's loveliest, especially in the May term, when the Master's little garden to our right glows with bright colour, answered across the stream by that of the Fellows; when the water is alive with gay little craft, gigs, punts, and canoes; and when the "ambrosial dark" of the Avenue before us beckons us on to explore the delights of its umbrageous depths. It was planted in 1691, and is carried for 150 yards on a wide embankment, dense with shrubs and closed with jealously-spiked gates at either end, across what was once an island in the river (known as Butts Close), till it debouches on to the elm-shaded length of greensward described in our opening page, and named, in old maps of Cambridge, "King's College Back-sides." The whole does, in fact, belong to King's, but the many rights of way which traverse it make it practically an open park.
