Seven o'clock
It was twenty minutes past three when Dick stepped over and nudged Dave gently , next whispering : `` It 's about time for you , now . You call Tom at a little after five , and then tell him to call us all at seven o'clock . '' Dave hurriedly dressed and took the air rifle from Dick , the latter then getting back into his bunk and soon dropping off in sleep . `` Seven o'clock ! All out ! Step lively ! Change cars for breakfast ! ''
