We 'll shine in more substantial honours,
And to be noble we 'll be good.
In came Mrs. Fezziwig, one vast substantial smile.
Dreams, books, are each a world; and books, we know,
Are a substantial world, both pure and good.
Round these, with tendrils strong as flesh and blood,
Our pastime and our happiness will grow.
