It is towards the end of an afternoon in December, and Wilfred Rolleston is walking along a crowded London street with his face turned westward. A few moments ago and he was scarcely conscious of where he was or where he meant to go: he was walking on mechanically in a heavy stupor, through which there stole a haunting sense of degradation and despair that tortured him dully. And suddenly, as if by magic, this has vanished: he seems to himself to have waked from a miserable day dream to the buoyant consciousness of youth and hope. Temperaments which are subject to fits of heavy and causeless depression have their compensations sometimes in the reaction which follows; the infesting cares, as in Longfellow's poem, 'fold their tents, like the Arabs, and as silently steal away,' and with their retreat comes an exquisite exhilaration which more equable dispositions can never experience. Is this so with Rolleston now? He only knows that the cloud has lifted from his brain, and that in the clear sunshine which bursts upon him now he can look his sorrows in the face and know that there is nothing so terrible in them after all. It is true that he is not happy at the big City day school which he has just left. How should he be? He is dull and crabbed and uncouth, and knows too well that he is an object of general dislike; no one there cares to associate with him, and he makes no attempt to overcome their prejudices, being perfectly aware that they are different from him, and hating them for it, but hating himself, perhaps, the most. And though all his evenings are spent at home there is little rest for him even there, for the work for the next day must be prepared; and he sits over it till late, sometimes with desperate efforts to master the difficulties, but more often staring at the page before him with eyes that are almost wilfully vacant. All this has been and is enough in itself to account for the gloomy state into which he had sunk. But--and how could he have forgotten it?--it is over for the present. To-night he will not have to sit up struggling with the tasks which will only cover him with fresh disgrace on the morrow; for a whole month he need not think of them, nor of the classes in which the hand of everyone is against him. For the holidays have begun; to-day has been the last of the term. Is there no reason for joy and thankfulness in that? What a fool he has been to let those black thoughts gain such a hold over him!
