I don't think that W. V., in spite of her confidence in my good faith, was quite convinced of the existence of those old forests of which I had told her, until I explained that they were forests of stone, which, if men did not mar them, would blossom for centuries unchanged, though the hands that planted them had long been blown in dust about the world.  She understood all that I meant when we visited York and Westminster, and walked through the long avenues of stone palms and pines, with their overarching boughs, and gazed at the marvellous rose-windows in which all the jewels of the world seemed to have been set, and saw the colours streaming through the gorgeous lancets and high many-lighted casements.  After that it was delightful to turn over engravings and photographs of ruined abbeys and famous old churches at home and abroad, and to anticipate the good time when we should visit them together, and perhaps not only descend into the crypts but go through the curious galleries which extend over the pillars of the nave, and even climb up to the leaded roof of the tower, or dare the long windy staircases and ladders which mount into the spire, and so look down on the quaint map of streets, and houses, and gardens, and squares, hundreds of feet below.
