In the season of 1757 Foote produced at Drury Lane his comedy of _The Author_, that principally turns on the distresses incident to a writer dependent on his pen for his daily bread, and on the caricature of a gentleman of family and fortune, whom he entitled Cadwalader, who appears ambitious to be thought a patron of the arts and sciences, of which he is profoundly ignorant. Cadwalader was a caricature of one of his most intimate friends, a Mr. Ap Rice, a man of fortune and education, and allied to many families of distinction. At his table, where Foote was hospitably received, in open and unguarded familiar discourse, Ap Rice had laid himself open to ridicule. The Welsh gentleman was stout, had a broad, unmeaning stare, a loud voice, and boisterous manner, and as he spoke his head was continually turning to his left shoulder. The farce was performed for several nights to crowded audiences before Mr. Ap Rice felt the keenness of the satire. At last the joke became so serious, that whenever he went abroad, in the park, the coffee-house, or the assembly, he heard himself spoken of as Cadwalader, and pointed at with suppressed laughter, or heard quotations from his part in the play: "This is Becky, my dear Becky." Mightily offended, and really hurt, he applied to Foote to have the piece suppressed. But this Foote would not hear of--it was drawing crowded houses. Then Ap Rice applied to the Lord Chamberlain and obtained an injunction to restrain the performance. Dr. Johnson was informed by a mutual friend that Foote was going to produce an impersonation of him on the stage. "What is the price of a cane?" asked the doctor. "Sixpence." "Then," said he, "here is a shilling; go and fetch me the stoutest you can purchase, and tell Mr. Foote that at his first performance I shall visit the theatre, go on the stage, and thrash him soundly." This was repeated to the mimic, and he deemed it advisable to desist from _this_ impersonation.
