 note = {A distribution of the neutral carbon atom (C i) in Heiles cloud 2 (HCL2) has been investigated with the Mount Fuji submillimeter-wave telescope. A region of 1.2 deg2 covering a whole region of HCL2 has been mapped with the 3P1?3P0 fine-structure line (492 GHz) of C i. The global extent of the C i emission is similar to that of 13CO, extending from southeast to northwest. However, the C i intensity is found to be rather weak in dense cores traced by the line of C18O. On the other hand, strong C i emission is observed in a south part of HCL2 in which the C18O intensity is fairly weak. The C i/CO abundance ratio is greater than 0.8 for the C i peak, whereas it is 0.1 for the dense cores such as the cyanopolyyne peak. The C i?rich cloud found in the south part may be in the early evolutionary stage of dense core formation where C i has not yet been converted completely into CO. This result implies that formation of dense cores is taking place from north to south in HCL2.},
