Cherry Hinton itself is not yet absorbed by Cambridge, and remains a bright spacious village, with a rarely beautiful church. The exquisite Early English chancel is lighted on either side by four couplets of lancet windows, in ideal proportion, while five equally ideal lancets serve for an East window. Both walls have an arcading of cinque-foil pattern; and the double piscina and the graduated sedilia are of no less merit. All this loveliness is within a fine oaken screen of the fifteenth century, and the rest of the church is not unworthy of it. The great quarry, whence the "clunch" of which the church is mainly built was drawn, is a conspicuous object on the hill-side above the village; and above that again, equally conspicuous, is the reservoir of the Cambridge Water-works, looking like a redoubt, on the summit of the slope. At the foot clear springs break out from the chalk, which are also utilised to supply the town. Close to the reservoir there is an actual fortification, an ancient earthwork, known as the War Ditches, which the researches of Professor Hughes have shown to be of British date.[154] At the bottom of the fosse he discovered rough British pottery along with the bones of domestic animals, and above these a layer of disjointed human skeletons of both sexes and all ages, apparently due to a general massacre, in some prehistoric struggle, of men, women, and children, whose corpses were hurled over the parapet. Above these again came Romano-British remains. From this earthwork the line of an ancient dyke, now called Warstead Street, may be traced to the East Anglian heights near Horseheath. [Footnote 154: Hughes' _Geography of Cambs_, p. 139.] Till the nineteenth century the fields between Cherry Hinton and Cambridge were bright with the purple flowers of the saffron crocus, which was grown, as it was by the ancient Greeks and Romans, for medical use and for dyeing purposes. Its cultivation may very probably have been introduced into Britain by the Romans. The saffron here grown was considered the best in Europe, and fetched no less than thirty shillings a pound. But its use, after so many centuries, suddenly went out of fashion, and the plant is now wholly extinct in Cambridgeshire.[155] [Footnote 155: _Ibid._ p. 96.]
