PRESERVING MILK.
,DrFz1NG IT FOR SHIPMENT. OR RE-
DUCING IT TO POWDER.


-u.o new ideas in regard to milk have recently
-, advanced. One relates TO the possibility
= h-i,eiDg supplies to the metropolis from very
- greater distances than are now common.
. p,ookIyn retailer of dairy products said the
.h., dav: IF prices go much higher We may

--.to,as That's a long way but if the stuff

ne have refrlgtrator cars for beef. Why not
for milk"
.-otber excellent authority who was con-
.,,ad on the subject declined to express any
Union as 10 the practicability of the scheme.
-. he was confident that New-York City can
80, all the milk il Will need for the next
.sonsand years without going further than fifty.
= avav. He believed that Long Island
.,o,e has room for all the dairy farms required
for this purpose
the opinion Of DR.. H. ". Wiley, chief chemist
:, +be Department Of Agriculture in Washing
~ was sought on another phase of the sub
,ec, Being asked whether the food value of
tbe milk would be impaired in any way. he re-
Piled as follows:
,I,, observation is that freezing has no effect
mon milk provided. after thawing slowly, the
n.ss is again thoroughly mixed. There is a
tsndency. Of course. in the freezing to separate,
tbe water which is turned into ice, concen-
,-stes to a greater degree the solution of milk
SUGAR which is left behind. As the ice forms
@bisev AT the top on tina wing the aqueous layer
sr the top viii be less rich in milk sugar than
,bs other portions on shaking. however the
bomoceneity Of the mixture is restored.
WHY milk should he Intentionally frozen be-
fore shipment l cannot understand, unless il he
t.n, frozen during shipment. OF course, milk
could he preserved for almost an indefinite time
in frozen condition. and this might make il
1xr,sr 1fcF.,
frigerate il. even To the freezing point for
transportation.
Should business Of this kind be established.
1. would be feasible To place imported supplies
+, 2 cold storage warehouse and keep them
there Indefinitely And if the traffic assumed
large proportions. it would perhaps be desirable
10 have special means for thawing the milk i'm
uediately before delivery to retail dealers This
operaon would rot be particularly expensive
The chief items OF cost. apparently. would be
refrigeration before shipment, and freight. The
latter would probably be high. since refrigerator
cars would be necessary Labor it may be
suned would he no cheaper in the West than in
the East. Winter feed could probably be had
at lower prices in Minnesota than New-York
but If is doubtful whether enough could be
saved in this direction 10 offset the cost OF
freezing transportation and thawing. IT, after
careful figuring. anybody wants to undertake
shipments Of this kind. the Brooklyn man will
ask no reward. But he is careful not to guaran-
tee the financial success OF the project.
The other novelty above referred TO is a Swed-
ish r1cshod cf preserving milk either for local
usc or shipment The United States Consul
at Gothen1.rg Robert s. s. Bergh describes IT
in 4 report To the State Department. DR.. NJ.
Thenherc. of that city claims to have invented
mill ba Of
POWDER like -four. The inventor declares that
TIE Product is easily soluble in water, and re-
tai-s al the qualities originally possessed, ex-
oept moisture.
/ Is asserted that so long as it is kept dry
tho powdered milk is not affected by weather
changes. and neither ferments nor grows sour
IN 'his respect it differs from some of the con-
ia ii milk now manufactured When can

tsrio-ates. and is apt 10 be wasted. The powder

CURED and every particle which is left is still

Precise nature Of which IS not described-is

The inventor exhibited samples and they
frcsed favorable comment. He suggests that
