Abstract
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.
