half past seven
Now then , Theo , we must have somebody to take charge of this room . Can you do it ? '' `` Yes , indeed . '' `` You know that means that you must be here every evening in the week , from half past seven to ten o'clock . You 'll want to be away sometimes , Theodore . '' `` Yes , I s ` pose I will , but I 'm ready to stay here all the same until night school begins again . '' `` Very well , then we 'll let it be so , and we 'll try to have the room ready for our opening in a week or two -- as soon as we have enough books and papers to begin with . ''
