An instance of the interest of the public in a Lyceum production was shown by a letter received by Irving a few nights after the play had been produced. For one of the front scenes the scene-painter, Hawes Craven, had been given a free hand. He chose for the subject a walk curving away through giant cedars, brown trunks and twisted branches—a noble spot in which to muse. Irving’s correspondent pointed out, as well as I remember, that whereas the period is set in the third quarter of the fifteenth century, the cedar was not introduced into Messina until the middle of that century and could not possibly have attained the stature shown in the scene. Perhaps I may here mention that Irving had some other experiences of the same kind: When he reproduced _Charles I._ in June 1879, some critical observer called attention to the fact that the trees in the Hampton Court scene, having been planted in the time of Charles, could not possibly have grown within his reign to the size represented. Again, whilst in Philadelphia in 1894, where we had played _Becket_, the secretary of a Natural History Society wrote a letter—a really charming letter it was too—pointing out that Tennyson had made a mistake in that passage of the last act of the play where Becket speaks of finding a duck frozen on her nest of eggs. Such might certainly occur in the case of certain other wild birds; but not in the case of a duck whose habits made such a tragedy impossible. Irving replied in an equally courteous letter, saying, after thanking him for the interest displayed in the play and for his kindness in calling attention to the alleged error, that there must have been some misreading of the poet’s words as he did not mention a duck at all! “... we came upon A wild-fowl sitting on her nest....” V
