[29 April 1915: Testing the motor sledge on the ice again. During one of the breakdowns of the motor, Worsley and Shackleton danced a one-step, while one of the crew whistled ‘The Policeman’s Holiday.’]

“It was most amusing and not a little incongruous to see the great polar explorer thus gyrating on the Antarctic ice. That is Sir Ernest all over though. He is always able to keep his troubles under and show a bold front. His unfailing cheeriness means a lot to a band of disappointed explorers like ourselves. As most of our number are prone to regulate their demeanour by his, perhaps it is just as well that he is able to conceal his disappointment by his strong will so splendidly.”
