## . 3. A determined effort is under way to check up on Sammons' veracity (and sanity!) I have neither seen nor talked to Sammons, but another member of the Institute of Meteoritics party (Dr. D. M. Gragg, an Instructor in the Department of Mathematics) who did so believes Sammons (who is a well-to-d0 farmer) to be sincere and very badly scared. Of course nearness to a big meteorite fall would scare one as badly as an atom bomb; but how could it produce such testimony as Sammons". ## . The "meteoritic" incidents from the great fall of 1945, November 29 (from which no meteorites have been recovered either!) through the sequence of similar falls culminating in the Four Corners and Norcatur incidents, coupled with such things as the Ussuri incident, convince me that either the earth is under a most unusual cosmic bombardment or many of the fireballs are not meteorites at all. While I still cling to the meteoritic hypothesis, it is clear that which ever alternative is the right one, the situation cries aloud for thorough investigation.
