about ten o'clock
`` Do n't I know this country ? Take it from me . '' I thanked him , and , turning , with a light heart I faced the black mountain and my journey . It was about ten o'clock when Hal jogged into a broad trail on the outskirts of Holston . A gray flat lay before me , on the other side of which began the slow rise of the slope . I could hardly contain myself . I wanted to run the mustang , but did not for the sake of the burdened pony .
