Comments on “Hail in Southwestern France. Part II: Results of a 30-Year Hail Prevention Project with Silver Iodide Seeding from the Ground” Mezeix, J. F. In a recent article, Dessens uses economic data to evaluate a nonrandomized hail suppression project involving seeding from the ground. Given the far-reaching repercussions of such an evaluation within both the scientific and agricultural communities the control method used and the results must be irrefutable. These comments have received the agreement of the scientific committee of the French Hail Program attributed to G.N.E.F.A. by the Ministry of Agriculture, the insurance company, and the agricultural organizations.

Comments on “Lateral Dispersion from Tall Stacks” Briggs, Gary A. A few minor errors in a paper by Hanna are noted and several questions are raised about apparent inconsistencies. One question is why substantial enhancement of σy, by buoyancy was noted for the Bull Run data but was unmentioned for the Kincaid data; information given in the paper suggests similar ranges of X*/F* at both plants, but much smaller F* values at Kincaid, which may account for the lack of noticeable buoyancy effects there. The inconsistency between the recommended equation σy/x = 0.6 w*/u and the σy/x values recommended for various stability classes (based on u/w* ranges) can be removed by multiplying this σy expression by a factor which accounts for the effect of mechanical turbulence. Finally, it is noted that an identical equation was recently reported to give a good fit to σy from passive sources released above 0.3 h, albeit to much smaller distances than reported by Hanna.
