northern hemisphere. Maps are being
prepared. for use by forecasters OF the
government. which will include Irkutsk,
Tomsk and E~katerlnDurg, in Siberia.
In addition, the 'Icelandic low" which
mean the area Of low winter barom-
etec Of the North Atlantic. soon will
begin making reports by cable. The
opening Of cable service to Iceland, just
announced. will make this possible.
Already the weather bureau receives
reports from western Europe. including
London. Paris. Hamburg and half a
dozen points in Great Britain. Every

Broadly speaking. the northern hem
ispiere will report daily on its weather
conditions to the bureau in Washing

reports from steamships crossing the
Pacific by the great circle route.
Nome, Alaska. for the time being, will
be the extreme report from American
territory to the far Northwest. AS soon

The greatest land area on earth is
the immense continental plain from St.
Petersburg east to the Pacife-7.Oo0
miles in extent. This area has more to
dc with making weather than any 9th
err such area Oh earth. because land is
subject to greater extremes Of heat
and cold than water. Hence, to fore
cast weather, tits desirable to know
conditions prevailing over this land
area. It is this that the weather bu-
rear has arranged to do.
The arrangements just closed with
the Central Physical Observatory at
st. Petersburg will secure reports from
the points named in this great area
Of land expanse. With them the whole
realm Of possibilities Of weather fore
casting will be vastly enlarged. Wash
ington for The first time will be able
to reckon intelligently with world con-
ditions, and as the experts become ia
miliar with these conditions in detail,
they will make accurate forecasts for
a far longer time than ever before.
