USEFUL REcIPEs.-A simple meth
cd Of determining the quantity Of
cream in any sample Of milk consists
in agitating the milk in graduated
glass tube with It's bulk of either for
four or FIVE minutes. Add alehohol
in volume equal to that Of the milk,
and shake for FIVE minutes. Place
the tube vertically and allow it to
rest for a brief period, when the oily
matter will rise to the surface so that
its amount may be read off on the
scale and the per centage easily COM
puted.
A good transfer paper for copying
monumental inscriptions and metal
lie patterns may be made by rubbing
q mixture of black lead and soap ov-
er the surface of common silver pa
per.
An OK viii consume two per cent.
of his weight of hay per day to
maintain his condition. If put to
moderate labor, an increase Of this
quantity to three per cent. will ena-
bic him to perform his work and yet
maintain his flesh. If he is to be
fatted, he requires about four and
half per cent. of his weight daily in
nutritious food.
The strongest side Of a piece of
timber is that which in Its natural
position faced the north.
A good zinc wash for rooms is made
of oxide of zinc mixed with common
size, and applied like whitewash.-
After it Is dry, put on q wash of
chloride of zinc, which will produce
a glossy surface.
Too great care of the health at this
period of the year cannot be exerci-
sed. Because Il few Gays are open,
bright, and warm, all the windows
in the house should not be thrown
open, the fires put out or fan3eiS
thrown aside. 1t is better to err on
the safe side, and endure the tri1ing
discomfort, than by free exposure, to
invite pncumania and other diseases
common during the wet weather Of 4
late spring.
WATERING Milk TO GETTHE CREAM
1t is well known thatmilk set in the
usual way, although it throws up
goodly per centage of cream, does not
yield up all the fat in the milk, be-
cause the SKINNED milk, on being
subjected to analysis, is found to con-
tain a small per centage OF butter,
Notwithstanding it had on being set
thrown up the cream very perfectly.
Experiments that have been made in
adding water to milk to facilitate the
rising of the cream have shown that
more cream is obtained. Thus spe-
cimen of milk was divided into two
portions. One portion was set for
cream, and in seven hours yielded I
per cent. of cream. The other port
ion was mixed with an equal volume
of water and the diluted milk set for
cream. The diluted milk in seven
hours gave 81 per cent. of cream, or
D per cent. more cream than it should
have yielded if watering made no
difference. 1t may not be advisable,
however, to use the water in this
way on all occasions for getting up
the cream, since water added to milk
hastcns the acidity of the liquid,
which in warm weather should be
guarded against.
CARE OF HORSES N SPRNG.-A
subscriber writeS:-I was always
taught to keep horses up, in the
spring, on dry feed, until the spring
work was done, for fear they would
not eat their food if turned out, and
would therefore fall off in flesh. But
for the last fouryears, when We began
work in the spring, l have given my
horses a run Of an hour ormorc eve
ry day, even when the grass was
well started, and have found that
they feel better, and keep in better
flesh, than under the old rule The
grass keeps the bowels open, and the
rolling is the natural method of cur
rying. keep two horses only-com-
binca weight, 2,l50 pounds-yet they
do all the work on farm of $50 ac-
res.
