/ Farmer).
AS is well known, the North Dakota
experiment station has for a number
! of years worked upon the question Of
the use of chemical sprays in destroy
| ing weeds in cereal grain fields, Pro-
! fessor Bclley as an experiment station
man first undertook this work In Am
erica, and there seems to be no liter
AZURE to show that he was not the Or
| iginator of the work as conducted IN
| Europe. It is certainly true that tho
the experimental work was undertaken
at the North Dakota station in 1895 and
carried along very connectedly to the
present time by Bolley and his as
sistants, that there was no suitable
| ma hinery for such work to be found;
either in Europe or America, until the
| last three or four years.
| Professor Bolley has, during the
past three or four years, after becom-
ing convinced that the process was
One which would be of great value to
the northern farmers, especially ce-
Ireal growers, made every effort to get
spraying machinery manufacturers of
America to take an interest in the
l
such manner that the work could be
done by horse power, simply driving
over the fields. In his correspond
ence he found, to start with, firms
were not interested in the matter at
all. They had not been in the habit
= Of selling spraying machinery to
grain raisers. and did not believe the
| process feasible; hence. refused to
even establish agencies in the north
west territory. These firms. however,
have now recu gnized that a large
| field is open to them, and more than
a dozen spraying machine manufac-
turers are busily engaging in compet-
| ing for the farmer trade in these ma
| chimes.
He has been specially interested in
getting firms to strengthen their ma
! chimes, and at the same time simpli-
| fly them so that they can be handled
by any ordinary teamster. In the
last two or three years much i'm
provement has been made in many
Of these machines, and it is believed
that soon the field spraying machine
will be looked upon as part of the
/ farm equipment and the professor
predicts that it will eventually be as
serviceable in increasing crop values
| in the case of potatoes, cereal grains.
etc, as that of any one Of the farm
implements. Several of the spraying
| firms however, have so perfected
their machine that they are simple,
/ and quite complete for the general
/, field spraying.
The professor IS at present engaged
~ IN cp,.o opnona Mas
ideas of making special equipment in
connection with these sprayers. which
will allow the machines to be handled
, either as hand sprayers or general field
! sprayers That Is to say, he has asked
the companies to make It possible to
attach one or more lines of pressure
hose to the machine In such manner
that while the machine IS being driven
thru the field the spray can be thrown,
either from the general spray beam or
from nozzles directed by hand. The
object of being able to direct the noz-
zles by hand will be apparent to those
farmers who have lands infested by
Canada thistle and patches of weeds.
Furthermore, even mustard may be
scattered thru the field in small clu1nps,
such that it is not desirable to run the
spray beam all Of the time. A man, or
a couple of men, carrying the hose with
nozzles attached, walking behind the
machine, would be able in this manner,
to make a large saving Of the spraying
! solution, and catch all of the scatter
ing clumps. The method becomes al
most essential to those who wish to
fight the Canada thistle, because with
this weed it is desirable to use sodium
! arsenite or strong salt solution, both of
which, when made strong as they
should be- to be most effective, are apt
under certain conditions to be too
strong for general use over the grain
by means of the regular spray beam.
The only added expense will be the in
PRODUCTION of two or three water cock
by means of which the fluid can be
shut off from the regular spray beam,
and the pressure applied to the noz-
zles, and the purchase by the farmers
of the necessary strands of pressure
hose. which should probably be twenty
to thirty feet long, and not to exceed
three eighths of an inch in bore. The
nozzles are to be carried on poles as
In the case Of tree spraying. Several of
the companies have agreed to equip
their field sprayer for the coming sea-
son.
OF noise alone is born the inward
sense of silence, and from action
springs alone the inward knowledge Of
