`` I 'm a chump , on guard duty , and I admit it , '' Darrin went on , looking sheepish . `` Dick , when you found me asleep why did n't you call me ? '' `` Because , '' Prescott answered , `` when you went to sleep I judged that you did so because you needed the rest . '' `` I must have been sound asleep from at least one o'clock in the morning , '' Dave went on ruefully . `` Oh , I am a fellow to be trusted , I am ! '' `` If you 've been sleeping , with your back against that tree , from one in the morning , you must be as stiff and lame as you could possibly be , '' Reade suggested . `` I am pretty lame , '' Darrin confessed .
