Emission from the J=1..-->..0 transition of carbon monoxide has been mapped over an area of 40' x 55' in cloud L134, and visual extinctions over the entire cloud have been obtained by means of star counts. Line intensities of > or =2 K are observable down to an extinction level of about one magnitude. From observations of the J=1..-->..0 transition of the /sup 13/CO isotopic species at 18 locations in the cloud, we have found a linear correlation between the local thermodynamic equilibrium (LTE) column densities of /sup 13/CO and magnitudes of visual extinction.
