Government Exhibit of Weeds.
The exhibit Of weeds and weed seeds
by the United States Department of
Agriculture is well worthy of mention.
To know them is the first step toward
keeping weeds in check. In the past
some of the most dangerous and
troublesome ones have spread over
whole townships before they were rec
ognized. The ignorance regarding the
identity of weeds is surprising. Science
has to a large extent discovered the
easiest way Of keeping each kind of
weed in check. The knowledge thus
gained is disseminated by the agricul-
tural press and by the station bulletins.
But what good does it do for a man
to know how to treat a weed If ae does
not know the weed when he sees it?
Exhibits of weeds are therefore neces-
sary and are sure to be appreciated by
the men that want to learn.
The weeds exhibited at Buffalo are
growing in pots and comprise only the
most common kinds, among which the
writer noticed the following: Curled
dock, sorrel, rough pig weed, smart
weed, ragweed (ambrosia artemisoe-
folia), wild carrot Caucus car
ota), lambsquarter, also called pig
weed (~chenopodium album, ~plantain,
crabgrass, buckhorn (ripple), witch
grass, yellow foxtail, chess Cheat,
and mayweed.
Seeds of weeds and of our common
grasses were shown in open glass
bowls, closed glass tubes, and also un-
der microscopes. A strong instrument
of this kind was placed before every
kind of seed with a sample under it
ready for inspection. This was done
for the purpose of familiarizing the
visitors with the characteristics of
each kind of seed. The samples were
of those most likely to be found in the
cultivated fodder plants and grasses.
There were seeds of the weeds men
toned above and in addition seeds of
COW cookie, corn cookie, field dodder,
oXeye daisy, yellow f~oxtail, green fox
tail (pigeon grass), pepper grass and
trefoil. Among the seeds of cultivated
grasses were those of alsike clover,
alfalfa, red clover, red top, beardless
bronze grass, Kentucky blue grass and
orchard grass.
1t is advisable for the farmer to
know all the seeds mentioned, as the
seeds of the grasses mentioned are
quite commonly rendered impure by
containing large amounts of the seeds
of the weeds mentioned. A dollar lens
in the hands of a farmer familiar with
these seeds will make it possible TO de-
tect the presence among commercial
seeds of obnoxious weed seeds. A gen
eral knowledge of this kind would soon
render impossible the sale of seed i'm
pure or adulterated. Yellow trefoil
seed is used extensively as an adul-
terant of clover seed, and it so close
ly resembles the seed of red clover
that the ordinary buyer of clover seed
is unable to distinguish it from clover
seed. But the microscope reveals some
distinguishing features. The clover
seed of whatever color has a triangular
formation, with broadly rounded cor
ners. This triangular formation is not
likely to be noticed by the amateur I'M
less his attention be called to it. The
seed of ~trefoil, on the other land, has
none of this formation. but is quite
fiat and bean-shaped. Its color, too, is
more of the yellow order, and it does
not have the purplish cast as do many
of the seeds Of red clover. Moreover
it lacks the gloss. The man that finds
the seeds of yellow trefoil in his clover
seed should know that it has been in
~tentionally adulterated, as the yellow
trefoil has habits of growth that make
it unlikely that its seed would get
mixed naturally with the seeds Of red
clover. When the seed of yellow ire
foil is thus found, the quantity is like
ly to be large, as some of the mixers
claim that as high as 30 per cent can
be mixed with red clover seed with
GU detection by the purchaser.
A Theory That Wants a Base.
