Ⅱ．Passage translation．

I had not visited Eton for many years，when one day passing from the Fellows＇Library into Gallery I caught sight of the portrait of my school-friend Digby Dolben hanging just without the door among our most distinguished contemporaries．I was wholly arrested，and as I stood gazing on it，my companion asked me if I knew who it was．I was thinking that，beyond a few whom I could name，I must be almost the only person who would know．Far memories of my boyhood were crowding freshly upon me: he was standing again beside me in the eager promise of his youth; I could hear his voice; nothing of him was changed; while I，wrapt from him in a confused mist of time，was wondering what he would think，could he know that at this actual moment he would have been dead thirty years，and that his memory would be thus preserved and honoured in the beloved school，where his delicate spirit had been so strangely troubled．

This portrait-gallery of old Etonians is very select: preeminent distinction of birth or merit may win you a place there，or again official connection with the school，which rightly lives to keep up an unbroken panorama of its teachers，and to vivify its annals with the faces and figures of the personalities who carried on its traditions．But how came Dolben there?It because he was a poet，that I knew; and yet his poems were not known; they were jealously guarded by his family and a few friends: indeed such of his poems as could have come to the eyes of the authorities who sanctioned this memorial would not justify it．There was another reason; and the portrait bears its own credentials; for though you might not perhaps divine the poet in it，you can see the saint，the soul rapt in contemplation，the habit of stainless life，of devotion，of enthusiasm for high ideals．Such a being must have stood out conspicuously among his fellows; the facts of his life would have been the ground of the faith in his genius; and when his early death endeared and sanctified his memory，loving grief would generously grant him the laurels which he had never worn．
