detailed account of the seeding flight.
On the other two sheets there is a carbon
copy of their report of their operations
for the 6th of July, 1959. I think it is
well to say that we have the best coopera-
tion from the Weather Modification Company
because they too are highly interested in
knowing just exactly what effects their
operations are having on the northeastern
Colorado area.

So much for the type of data that we
are collecting. The type of analyses to
be perfomed I think can be summarized as
two major points. First of all, we think
we can delimit the anomalies, that is, the
departures from nomal, that exist in north-
eastern Colorado this season and we hope we
can come up with some answers as to whether
or not we have one inch more or two inches
more or perhaps one inch less or two less of
precipitation over the area. That's item
No.1.

The second item is, has there been a
change in the relation between rain fall
amounts and hail occurrence in the area as
a result of this seeding treatment? For
~nstance, this hypothetical question is
frequently posed: 'If it is possible to
suppress hail by a given fraction, say ten
percent, does it follow, naturally, that .
there will be a reduction in precipitation
amounts by ten percent or can we perhaps
eat our cake and have it too, suppress hail
and increase precipitation?'. This is the
question that we think we can answer or we
can get some answers on from this particu-
lar study.

As far as anticipated results are con-
cerned, I think it is easiest to simply show
you a series of charts here that would give
you the type of results that we think could
be obtained from this study. The first is
simply a delimitation of the anomalies in
precipitation that would be received over
the area. This is a very rough outline of
the northeastern corner of Colorado in the
area from Julesburg to Sterling on down to
Fort Morgan. This is a hypothetical case
of what we think we might find at the end
of the season; departures from nomal plus
