Under his own eye and of conscious purpose a circle of imitators grew up in the fabrication of Christmas stories. They obviously formed themselves upon his sobered ideals; they collaborated with him, and it was often hard to know whether it was Dickens or Sala or Collins who was writing. The Christmas book had by that time lost its direct application to Christmas. It dealt with shipwrecks a good deal, and with perilous adventures of all kinds, and with unmerited suffering, and with ghosts and mysteries, because human nature, secure from storm and danger in a well-lighted room before a cheerful fire, likes to have these things imaged for it, and its long-puerilized fancy will bear an endless repetition of them. The wizards who wrought their spells with them contented themselves with the lasting efficacy of these simple means; and the apprentice-wizards and journeyman-wizards who have succeeded them practise the same arts at the old stand; but the ethical intention which gave dignity to Dickens's Christmas stories of still earlier date has almost wholly disappeared. It was a quality which could not be worked so long as the phantoms and hair-breadth escapes. People always knew that character is not changed by a dream in a series of tableaux; that a ghost cannot do much towards reforming an inordinately selfish person; that a life cannot be turned white, like a head of hair, in a single night, by the most allegorical apparition; that want and sin and shame cannot be cured by kettles singing on the hob; and gradually they ceased to make believe that there was virtue in these devices and appliances. Yet the ethical intention was not fruitless, crude as it now appears.
