about four o'clock
When they had finished this rural but eminently satisfying repast , they hurried over to the one big general store to buy a few supplies that they would need that night . It was necessary to lay in only a limited amount , as Grace 's aunt Mary had thoughtfully left her cottage well stocked and had informed them that eggs , chickens and vegetables of all kinds could be had fresh from the farmers round about . Then they were off again , eyes upon that ribbon of road in front , intent upon reaching their destination before nightfall . It was not till about four o'clock that they met with their first setback . Betty had just rounded a turn in the road , horn honking for all it was worth , when she found herself almost on top of a huge farm wagon . She yelled to the driver and put on her brakes hard , hoping desperately that Mollie would not run into her from behind . Grace shrieked and covered her face with her hands .
