Sixty Day is similar variety, fro1
the same country, but ripens a little
sooner than the Kherson. For irri-
gated lands the long season sorts do
better. OF these the Swedish Select,
or White Swedish, is the very best

ley or other high attitudes.
Colorado No. 81, a variety discov-
cred and propogated here on the COL
lege grounds by Professor Olin. gives
the very highest yields. 1t resembles
closely the Swedish Select. We have
had no opportunity to test 1t over
the state as yet. Seed that has been
grown and cared for in the home
vicinity will be found, other things
being equal. to give the best results
kherson will do better than other
varieties in alkaline soils.
In wheats none compare with Tur-
key Red. On irrigated land 1t has
frequently averaged with seventy
bushels. On dry farms it averages
forty-five and fifty bushels. Sow it.

Soil Poisoning

; we will not have any fruit trees.
Samples of apple. pear and peach
> trees were shown, burned to death
in root and branch by arsenic. and
showing under chemical analyses as
. high as thirty parts arsenic to the
million.
Not all the trees that die in Coio-
RADIO are killed by poison, but the
percentage is very. very great. The
trouble is not difficult to distinguish.
: An examination of the root OF a Iois-
| oned tree will show all or part uf it
: BACKED and charred as If burned.
/, 1t is not necessary that the tree be
t sprayed to become poisoned. AL elm
I whose roots traversed the ground
, occupied by an orchard twenty-five
y feet away was found to be dying on
= one side. The root was dug up and

i chardist desiring to kill some cotton
d wood stumps placed on the newly
$ cut stump a teacup of arsenatc of
d soda. In two days his apple trees
thirty feet from the stumps had turn
/ ed black, and their roots charred as
d II by fire. An examination showed
IS that their roots went to the poisoned
e stump.
A. 1t is an open question as to tn
., amount of damage that has been
le done in the state as a whole, but il
m is very large. 1t has been proven
lr that one part per million of solubh
arsenic in the soil is deleterious to
t. plant growth. What then must hap
is pen. when. after repeated sprayings
e continued year after year the soil
e shows as much as sixty parts OF ar

in a season and that at the right
