An area of 866 square degrees was covered at an 8' grid spacing with a 2.7' beam, and 48750 positions were observed. Significant ^13^CO emission (>=1.8K.km/s=3{sigma}) is detected at 1015 positions. On the basis of the ^13^CO data, 188 distinct ^13^CO clouds are identified whose total mass is 1.0x10^5^M_{sun}_. Physical properties of the ^13^CO clouds such as molecular column densities, sizes, and masses are derived for each cloud. Astronomical objects associated with the ^13^CO clouds were searched for in the literature: 10 H II regions, eight reflection nebulae, 23 T Tauri type stars, 28 molecular outflows, and 125 IRAS point sources selected as candidates for protostars are likely to be associated with the ^13^CO clouds.
