This will inaugurate one of the
most severe storm periods of the

1t Will be entering the North Atlantic

So far this season the severe storms
have come near dates predicted but
little later than expected Next bull
letin will give general forecasts of
June crop weather which is expected
to have important effects on crops.
Coming.
The weather bureau has put out it's
first long range forecast and announc-
cd that they will be published week
ly. giving forecasts for the week fol.
lowing. Professor Garriott is the long
range forecaster. He Is the chief Of
all the short range forecasters of the
weather bureau and his long range
system has the same basis as their
short range system. Professor Gar
riot believes that similar weather fol-
lows similar conditions both in short
and in long range. He takes the
weather map Of today, showing what
the conditions are on all parts Of the
continent; then selects similar maps
OF former years and concludes that the
weather of the week to come will be
an average Of the weather that fol-
lowed similar maps of past years.
This idea mas some merit but It
surely is not scientific. With that
basis Professor Garriott should be
able to make some good guesses, but
am Of the opinion he will make a
worse failure than did Professor Bige-
low when he tried to make long range
forecasts for the weather bureau.
Professor Bigelow's system is scienti-
fic but he gave up too quickly. If he
had got up and gone on as I have.
when he got knocked down he might
have found his error.
I am exceedingly we'll pleased that
Professor Garriott, backed by the
weather bureau, has come before the
public and IT challenge him and the
weather bureau to mortal combat" at
forecasting. am ready for the con-
test and more than willing that the
general public snail be the arbiter.
| OF course the contest will be I'M
equal because my forecasts are from
two to ten times as far in advance as
those Of Professor Garriott. My read
ers are requested to make notes Of
the results of both forecasts and in
form me as to their opinions of the
same.
