`` I 'll stay awake a few hours , and then call Ira , '' said he , `` and then Ira can call Dave . '' And so it was arranged . Dave was tired by the hard journey , and it was not long before he was sound asleep . He did not awaken until four in the morning , when Sanderson aroused him . `` Why did n't you call me before ? '' he cried , leaping up . `` I want to do my full share of duty while I am out with you . ''
