three o'clock
`` How is that , Count ? '' `` It will be your duty to call upon every gentleman to whom I have introduced you ; that is to say , to leave a card at the door , and every one of them will leave a card at my house for you . I will make out a list for you in the morning of the names and addresses . You will find a sledge at the door at three o'clock ; it will be at your disposal while you remain with me . It is a small and light one , like this , with a pair of horses . It is seldom that three horses are used unless ladies are of the party . There is much for you to see , and it will be more pleasant for you to be your own master and go about as you please . ''
