/ c. @. Schultz. state superintendent
OF education. has received good
many inquiries from teachers and su.
perintendents relative to the future
status of graduate teachers who are
not advanced normal graduates. The
/ new rule OF the high school board
passed recently and became effective
with the beginning OF the next school
year. This requires that new APP
pointees in the grades must be adj
vanced normal graduates, but does
not effect the status or rights of the
grade teachers properly qualified I'M
der the present rules who are holding
grade positions. such teachers, says.
Mr.. Schultz. may continue In their
present positions or in similar posi-
lions elsewhere. The same general
provision would obtain in the case OF
home economies teachers qualified
under the present rules and holding
teaching positions in public schools.
superintendents Are Notified.
Mr.. Schulz's report. which has heen
sent 10 the superintendents OF the
state, further states that teacher
holding first grade certificate or ele-
mentary normal diploma. without ex-
perience In the grades OF graded
school or of n high school, will not
be eligible for such n position. The
rule which has been adopted by the
board and which becomes effective in
September, 1915. states that grade
teachers must be graduates of the
advanced course of a state normal
school. and primary teachers must
in addition have qualified by pursuing
course which has includei special
training in primary work.
No teacher now in the service shall
be qualified on account of not being
graduate OF n state normal school
when the rule becomes effective.
Holders OF second grade certificates.
limited certificates first grade certif-
Gates issued by normal schools ana
graduates o. trimming departments of
high schools are not qualified to serve
as teachers Of any grade" Is the exact
wording of the new ruling.
Tests made at the Minnesota Expert
mont station under the direction OF
\. {. Army. OF the division OF agron.
envy and farm Infringement. show that
the quality OF alfalfa Is improved by
incubation and by tho use of lime
wherc line Is somewhat lacking In
tho soil. This Is true. not only. on
land Of moderate lrOdUctiveness. but
on land OF high productive quality.
Moreover the quantity OF the yield f.
increased.
Thi; Is contrary 10 the belief held
high product!yeness. incubation is
unnecessary. The general acceptanvc
of the conclusions. therefore. will
mean, not only larger alfalfa crops IN
Minnesota, but alfalfa richer in pro-
TEN, and so worth many more dollars
TO the acre.
The results OF the experiments con.
Quoted by Mru, Army have just been
tabulated, determinations as to nitro
gen content having been made under
the supervision OF Il. w. Thatcher. OF
the Division of Agricultural Chemis.
try
There were two separate sets OF
experiments. The first had to do with
highly productive lands. On these.
with no incubation or added lime,
AS tons OF feld-cured hay we're oh.
tanned from three cuttings. On SINH
lar land. with incubation but without
lime, 4.SJ tens OF alfalfa were cut, and
wien lime was added the tonnage was
increased to 507 With alfalfa at SIP
a ton. therefore. the value of the crop
was increased $i92 by inoculating and
sos by inoculating and using lime.
But analyses of the quality of the
crop showed that whereas the average
protein content was 1913 per cent
with no incubation. ii was 1858 per
cent with incubation alone. and 1855
per cent with inocnlation and lime.
Reducing these figures to dollars and
cents the gain in the quality OF the
crop was $3.50 by incubation and
Si3.36 by incubation and the use OF
lime.
II one is going to use highly produc.
tive land for alfalfa. therefore, these
experiments indicate that he should
inoculate with soil from other alfalfa
fields. and that. IL there is lack OF
lime in the soil, lime should be added.
On land of moderate productiveness
with no incubation, SO of a ton of
alfalfa were grown. With incubation
and lime the tonnage was increased
TO 1.51, gain of IS OF ton. worth
$10.56. The increase in the protein
content of the alfalfa was even more
remarkable. This jumped from 1918
pounds of protein TO the acre. to 47S.7
pounds. This increase at four ana one
half cents pound meant an added
return of STAG.
The inoculation in all of these ex-
periments' was made with soil from an
alfalfa field.
