There is a field Of wheat near Eve
sham which is like no other field Of
wheat in England, says the London
Graphic.
Up north. at Eamakewan, how
ever. there is a field Of oats which
looks very much ike II. On both these
fields there are rows of rough tele-
graph poles, about seventy yards apart
and some hundred yards between the
rows
On the top of each pole is an in
sulator ten times the size Of those seen
on ordinary telegraph poles The in
sulators carry the usual telegraph
wire. and extended between the rows
there are strands of thin wire, fasten-
ed to the telegraph wire. about ten
yards apart.
Very soon there will be a difference
perfectly visible 10 the passerby, be-
tween the part of the crop which is
below the wires and the part which Is
not The difference is due to dis
charges Of electricity from the curious
network. 1t is connected to wire
which runs to a little shed and from
that shed to a dynamo at the farm.
But it is what happens in the little
shed that matters The current from
the dynamo is transformed to high
tension and rectified by Sir oliver
Lodges well known valves, They look
rather like glass fire extinguishers. and
they glow in various tints.
There are about twenty one miles of
wire on the induction coil. Although
it is easy TO produce in the shed the
lightings and cracklings associated
with wireless telegraphy. nothing or
dinarily happens but slight sizzling
and much greater generation of
ozone than is pleasant.
The field wires are kept running at
the high tension OF 100000 volts.
Walking below the network barehead-
ed one feels a sensation as If brush

Any one who has a dynamo or ac-
cess to an electric cable could begin
experiments in electrification on be
tween five and ten acres at an expendi-
ture of about $500 To deal with sixty
acres the expenditure would be about
$1,000. Apparently what electrified
ton does is to give the plants kind
of electrical massage That was Sir
Oliver Lodges phrase. The discharges
are not needed on fine. sunny days
but in dull weather they take the place
Of sunshine.
OF course the whole problem OF the
nutrition Of plants is obscure. 1t is
perfectly clear that this discharge or
high tension electricity has done some.
thing to the crops treated. but what
exactly is In some doubt.
So far there Is no evidence of shock
ed Dlants suffering from premature
exhaustion due to overwork. Indeed,
there is some reason for believing that
the effect Of electriication is to give
the plant tone and go.
An American worker has shown that
electrical discharges help the micro
organisms Of the soil. so electrification
may be doing something In that direc-
ton too.
