Practice has shown that . Journal
made o. the same metal a. the Journal
box does not wear well. Under such
conditions the bearing soon ear out.
It II customary to make journal boxes
with . lining Of . softer, tougher metal
than that Of the Journal. Usually Bah
bett metal 10 used for such purposes,
but brass and bronze are commonly
used. Bearings made in this way give
less friction and, as . consequence,
last longer.
Q.-How much nitrogen DOES affalfa
put In the soil In q year?
Ans.-E. r.. Ladd, dean chemistry
department.. 5Sas.
It 10 not possible to say the exact
amount Of nitrogen that would be add
cd to the soil through the growth Of.
alfalfa for the period Of year. Il
Is generally stated, from experiments
that have been made. that the amount
Of organic matter included In the roots
and stubble is just about equal to tho
amount removed in the crop of alfalfa
or clover, and that the nitrogen con.
tent ID about the same for the two por
lions.
A recent analysis of q sample Of al
falfa grown In this state showed the
nitrogen content to be 2.S5 per cent.
II q crop in q season amounted to
three tons, 5000 pounds, and that POI.
tion, including stubble and roots be-
meath the surface, we're equal to that
removed, then the amount Of nitrogen
remaining in the roots and stubble
would be equal to about I'll pounds.
In other words, there has been gath
cred from the atmosphere and from
the various strata Of the soil II
pounds of nitrogen per ere and
brought into the form Of organic nitro
gen that win become easily available
for plant growth; but more than that.
the distribution Of this product
throughout the surface soil and the
large amount OF organic matter, have
made other changes which are vastly
important.
Q.-What h the difference betweon

dynamo has electro field magnets,
while the magnetic has permanent
field magnets. That 10. the dynamo

ings for the purpose Of exciting the
neld magnets. which are made Of soft
iron. The field magnets of the mag.
neto are made Of tempered steel and
are permanent magnets requiring no
windings.
Q.-What is the best way to handle
q burn?
Ans.-Alice G. Haggart. professor Of
home nursing.
Burns r Of first. second or third
degree, according to severity.
First degree (simple redness Of
skin)-Wash with bichloride solution,
10000 strength, to remove any infec.
ton Of the surrounding areas and ap-
ply lint saturated with carron oil
(equa& parts linseed oil and lime wa.
teri and cover with waxed paper and
light bandage. Later apply boric acid
ointment. ts
Note-one bichldride. tablet dis.
solved in one quart Of water II the
proper proportion. Thsss tablsts keep
for several months.
Second degree (formation Of Bills.
ters)-Puncture the blisters (vesci.
cles) with sterilized needle to let out
the Treat same . nrst de-
gree. X
Third degree ~(destruction Of skin OF
of deeper tissues)-Apply carbolated
vaseline or other ~antissptie. Dress
wound at least twice : day; oftener II
discharging.
Acid burns-Apply dry baking soda,
powdered chalk or lime for . few mo.
ments. These preparations nsutralize
acids.
sealds-Treat same q burns.
