Also we often had trouble when we gave the ballet "Don Quixote". The large number of additional artists and supers made it very difficult to stage the ballet on a small scale. Another difficulty was that this ballet required a horse and a donkey. When we gave it for the first time in London the donkey brought to the theatre was a beautiful little animal, but the coffee coloured horse appeared far too smart and wellfed for the part. The matter was put right by an artist-decorator, who happened to be working in the theatre. What he did was very simple; he painted such prominent ribs and gave the horse such a wretched look, that on the day after the performance an inspector of the RSPCA came to the theatre. He showed us a letter received by the Society from some tender-hearted old lady, saying that she had been indignant to see at our performance in what a terrible condition we kept our horse. But when he saw the horse without the make-up, the inspector was completely satisfied. It was only very tiresome that this make-up had to be put on anew at every performance for the horse's owner refused to ride it home in that state.
