PICTURESQUE DUNEDIN.
Hill Reefs. The stone is of considerable thickness, up to 14 feet, and strikes S. 76 deg. E. It dips northward at an angle of 55 deg., and is enclosed in soft phyllite. Several of the reefs carry gold, and some attempts have been made to work, but so far no success has attended the efforts, and the place is now let to a party of miners who are working surface stone.
