about nine o'clock Monday morning
The man got up to go . `` Well , good-night , boys , '' he said . `` Rest as hard as you can tomorrow . You 'll strike into the Sand Hills at about nine o'clock Monday morning . Take three days ' feed , and every drop of water you can carry ; and it you waste any of it washing your hands you 're bigger fools than I think you are . '' `` Come , stir out of that and get the camels ready for the desert ! '' This was Jack 's cheery way of warning Ollie and me that it was time to get up on the morning of our start into the Sand Hills .
