My methods of studying my subjects vary considerably, and the most successful of my caricatures have been without exception those which were made without the knowledge of the persons portrayed. After all, this is nothing more than natural, for by watching a man unawares one more successfully catches his little tricks of manner, and to some extent his movements, all of which are carefully concealed when he comes in the guise of a complacent sitter to the studio. And so, for the purpose of frank caricature, one prefers to rely upon memory. I have spent such a considerable time in public places of interest that I fear I am quite well known to the police. Not infrequently I have been detected in the act of obtaining my victims (by the pen), for I discovered the following account in a newspaper: "An amusing incident occurred one evening in the House of Commons Lobby in connection with the caricaturist and a victim. I had seen 'Spy' silently and patiently stalking a new member (Mr. Keir Hardie) with a striking and tempting personality. The new member, however, was nervous, having apparently an instinctive idea that he was being pursued, for he moved restlessly about, casting suspicious glances all round him. An evening or two after I was surprised to see 'Spy' and his victim engaged in a friendly conversation, the artist taking advantage of the opportunity to examine every detail of face and figure. It seems that the new member thought he recognized a friend in his pursuer, and not knowing what he was after, he went up to him feeling that he had found refuge, and that here at least was one man who did not want to sketch him. I need hardly say that 'Spy' took full advantage of the chase, and not long after this the victim appeared in _Vanity Fair_." That reminds me of the time when Lord Henry Lennox came up to me in the Lobby. "My dear," he said in his usual characteristic manner, "you see that little man over there--I detest him--he caricatured me and made me appalling." He took a violent dislike to Pellegrini, who had seized upon his obvious stoop with a wonderful touch, and converted it into one of his finest caricatures.
