make the termination of the Lady chapel, invisible from many points of view, seem infinitely distant. Of these mysterious distances, shadowy recesses and changing vistas, there is nothing in Lincoln and York; the whole eastern limb is seen at a single glance, and, unfortunately, is foreshortened by the eye. Wells and Salisbury internally look longer than they are, Lincoln and York much shorter. In mediæval days, however, the ritualistic divisions of the church were marked off by a series of screens, each adding apparent length to the interior. So many of these screens, however, have been swept away by Wyatt, Scott and the like, or replaced by paltry open-work, as at Lichfield and Durham, that many of the cathedrals of this type are now mere open barns; all sense of mystery, all sense of magnitude gone. Externally, York and Lincoln and Beverley have the best of it. The sweep of a sky-line, five hundred feet in length, at a height so vast, is sublimely impressive. The cost of an exterior kept at an unbroken height for such a distance is very great, but it is worth the cost. [Illustration: TRANSEPT] Cathedrals of the latter type, such as Ely, York, and Southwell, are quite presentable with a central tower of moderate height, provided that it is reinforced by more important towers to the west. An exterior of the former type, that of Wells and Salisbury, demands a very important central tower. Accordingly, every cathedral of this type has a big central tower—viz., St. Alban’s, Hereford, Wells; or a spire as well as a tower—viz., Chichester. (Winchester alone is an exception, an exception which proves how very much a central tower is needed in such elevations.) In such exteriors, looked at from the east, hills rise beyond hills, alps beyond alps, and the eye instinctively looks up to see the highest ranges aspire into the pyramidal outline of a Matterhorn. And this is what is given us at Salisbury. [Illustration: CHOIR.]
