A spectroscopic survey of high-latitude carbon stars shows that many of these stars are CH stars with characteristically high space velocities. Some newly determined CH stars and others compiled from the literature are employed to determine the local space density and kinematics of these stars. For the local space density, the surprisingly high value of rho = 5.6 x 10 to the -9th/cu pc is obtained for M(V) ranging from -0.25 to -2.2. The main result of the present study is that the velocity dispersion perpendicular to the galactic plane sigma(W) is always greater than approximately 114 km/s, irrespective of how the sample of known CH stars and CH star candidates is subdivided.
