With St. John's the Collegiate buildings cease and are succeeded by the last remaining "Hithes," or quays, used for commercial traffic, which of old lined the banks for the whole length of Cambridge. We read of Corn Hithe, Pease Hithe, Flax Hithe, Garlic Hithe and others. For the river was to old Cambridge all and more than all that the railways are now, the great artery of traffic, by which goods were far more easily and cheaply conveyed than along the roads of the period, which were always rough and often mere "Sloughs of Despond." Most especially was this the case with fuel, so that in the seventeenth century it was a familiar local saying that "here water kindleth fire." These ancient hithes, like the street-ways leading to them, have been almost all absorbed by the various College precincts. The last, as we have said, are to be seen yet, still in use, with barges (still laden chiefly with firewood) lying at them, below St. John's, by the side of the "Great Bridge," that famous passage of the river to which Cambridge owes both its name and its very existence. Opposite the lowest of them there is one more riverside College, Magdalene, an old monastic educational establishment turned to its present purpose at the time of the Reformation by Lord Thomas Audley of Saffron Walden, a courtier of King Henry the Eighth, who had obtained a grant of it from that rapacious monarch. Our Cam byway here ends; for the river here passes out of the populated area of Cambridge. It is noteworthy that this area abuts on its banks to the same extent and no more than it did seven hundred years ago. The King's Ditch, which then bounded it, left the stream at the King's Mill, where our voyage started, and rejoined it just opposite Magdalene, where that voyage closes. It is well worth while, however, to retrace our course, for we shall find fresh loveliness in the reverse views of the exquisite scenery through which we have passed; and may note the many disused archways in the College walls, which tell how, scarcely a generation ago, this unique gem of English landscape was actually defiled by being used as a shamelessly open sewer.
