We do not find any letter of Fox’s extant to tell us his opinion of the ‘tenth wonder.’ We can go with him to the play, nevertheless. ‘While young Betty was in all his glory,’ says Samuel Rogers, in his ‘Table Talk,’ ‘I went with Fox and Mrs. Fox, after dining with them in Arlington Street, to see him act Hamlet; and, during the play scene, Fox, to my infinite surprise, said, “This is finer than Garrick!”’ Fox would not have said so if he had not thought so. He did not say as much to Master Betty, but he best proved his sympathy by sitting with and reading to him passages from the great dramatists, mingled with excellent counsel. Windham, the famous statesman, who as much loved to see a pugilistic fight as Fox did to throw double sixes, and to whom a stroll in Leicester Fields was as agreeable as an hour with an Italian poet was to Fox--Windham hurried through the Fields to Covent Garden. His diary for the year 1804 is lost; but in that for 1805 we come upon his opinion of the attractive player, after visits in both years. On January 31, 1805, there is this entry in his diary;--‘Went, according to arrangement, with Elliot and Grenville to play; Master Betty in Frederick’ (‘Lovers’ Vows’). ‘Lord Spencer, who had been shooting at Osterley, came afterwards. Liked Master B. better than before, but still inclined to my former opinion; his action certainly very graceful, except now and then that he is a little tottering on his legs, and his recitation just, but his countenance not expressive; his voice neither powerful nor pleasing.’ The criticisms of actors were generally less favourable. Kemble was ‘riveted,’ we are told, by the acting of Master Betty; but he was contemptuously silent. Mrs. Siddons, according to Campbell, ‘never concealed her disgust at the popular infatuation.’ At the end of the play Lord Abercorn came into her box and told her that that boy, Betty, would eclipse everything which had been called acting, in England. ‘My Lord,’ she answered, ‘he is a very clever, pretty boy; but nothing more.’ Mrs. Siddons, however, was meanly jealous of all that stood between her and the public. When Mrs. Siddons was young, she was jealous of grand old Mrs. Crawford. When Mrs. Siddons was old, and had retired, she was jealous of young Miss O’Neill. She querulously said that the public were fond of setting up new idols in order to annoy their former favourites. George Frederick Cooke who had played Glenalvon to Master Betty’s Norval--played it finely too, at his very best--and could not crush the boy, after whom everybody was repeating the line he made so famous, The blood of Douglas can protect itself!
