XIII Noxious Weeds.


of North Dakota, who has made ex-
tensive experiments with different
preparations supposed to eradicate
mustard, dandelions and other nox-
ious weeds, expresses the belief that
iron sulphate, properly applied, with
the right kind of sprayer, will
keep down the objectional vegetation
without hurting the grass. Regard
ing its application he says:
'For ordinary lawn purposes the
ideal apparatus is the compressed air
type of hand spraying machine. 1t
is necessary that sufficient pressure
be maintained by the pump to make
forceful spray of fine form. If the
liquid is thrown in large drops, the
grass will be more or less injured
as the very young grass roots be-
meath the soil have slight power of
resisting the action of the chemical.
The capacity of the tank sould be
approximately three or four gallons
and it should be of such neat con-
struction that one can readily carry
it about without soiling the clothes.
Necessarily, if it is properly air tight
/ it will be free from leaks and chances
to spill liquids.
'The machine should be fitted
with about three feet of compression
hose and a three foot extension rod,
allowing one to readily swing the
nozzle over the lawn. The nozzle
should be of such nature as to
throw a rather flaring funnel shaped
spray. For city parks, roadsides,
and the larger lawns some one of
the traction carts will be found de-
sirable. Cities and towns will find
!. an economical way of grassing the
roadsides and causing the destruc-
ton of unsightly weeds. Every city
and town should possess one of more
' good spray carts and several hand
, sprayers, the latter to allow spray
$ ing to be done in waste places, diff.
! cult to reach with the traction spray.
