When the nation had presented the Duke of Wellington, after the Battle of Waterloo, with Strathfieldsaye, an estate between Basingstoke and Reading, the Duke wishing to commemorate the event planted a number of beech trees as a lasting memorial, which were known as "the Waterloo beeches." Some years later, the eminent arboricultural author, John Loudon, writing on the subject of the relative ages and sizes of trees, wrote to the Duke for permission to view his Waterloo beeches. The Duke had never heard of Loudon, and his writing being somewhat illegible he deciphered the signature "J. Loudon" as "J. London" (the Bishop of London), and the word "beeches" as "breeches." "For what on earth can the Bishop want to see the breeches I wore at Waterloo?" said the Duke; but taking a charitable view of the matter he decided that the poor old Bishop must be getting irresponsible and replied that he was giving his valet instructions to show the Bishop the garments in question, whenever it suited him to inspect them. The Bishop was equally amazed, but took exactly the same view about the Duke as the latter had decided upon concerning the Bishop. No doubt the mystery was eventually cleared up, and Bishop and Duke must have both enjoyed the joke. The shade of the beech is so dense that grass will not grow beneath it; it gradually kills even holly, which is comparatively flourishing under the oak. The beech woods in the Forest are thus quite free from undergrowth, and the noble trees with their smooth ash-coloured stems can be seen in perfection, giving a cathedral aisle effect, which is erroneously said to have suggested the massive columns and groined roofs of Gothic architecture. "Where thro' the long-drawn aisle and fretted vault, The pealing anthem swells the note of praise."
