of Commerce to formulate an appropriate national policy on weather mod-ification. While the whole domain is vast, the thinking of the general public and of many scholars focuses on the so-called cloud seeding as a means to enhance precipitation, rain or snow. In a recent article [I] I showed that, because of lack of randomization or because of defects in its implementation, the claims of success on the part of cloud seeding industry are not trustworthy. Also, the same article documents that the many reports from apparently authoritative sources are slanted and unreliable. On the positive side, the same article noted the phenomenon of unexpectedly large apparent effects of local cloud seeiing observed at unexpectedly distant areas. This phenomenon, observed in two seven-year long experiments conducted with marked effort at strict random-ization, appears as a most promising object of future studies. The above general picture of precipitation augmentation technology is confirmed by the recently published document [2] dated June 30, 1978. Thi
