diseussed with Dr. Peeples of this station the problems sncountered in
obtaining reliable information when observing unidentified objects.

tre QM sent to Dr. Peoples an information copy of his observations
near Arrey, Naw Mexiso on Avril 24, 1249. It is fait that aithough the
theodolite and stonp-wateh were of great assistance in making ostimates,
the principal factor responsible for the unusually specifics information
contained in this report, is that Mr. @a> wes meade aware in advance of
what faoters should be observed in case such an objact were sih .
thererore, it is urged that your office issue istailed adyance observae

Mre — — to Dr. Peoples an information copy of his observa
near Arrey, New Mexice on April 24, 1949. It is felt that although the
theodolite and stcop=watch wers of reat assistance in making estimates,

tha principal factor responsible for the unusually specific information
containad in this report, is that Mr. WUNR was meade aware in advance of
what factors should ba observed in case such an object were sighted.
Therafore, it is urged that vour office issus detailed advance observa-
tion instructions to people who might ba in a position to meke observations
and turn in reoortse
