In now antiquated number of London
Punch there is drawing which satirlzes
the villainous decoction which used to be
served to the London dairymen's customers
as milk, and in which the "cream" was
manufactured, and defed the ordinary laws
of the blending of liquids in most unmis-
taxable way. A servant girl receiving the
morning can from the hands of the milk
man, takes off the lid, and seeing the sus-
piciously blue tint of the contents, says:
But where is the cream?"
Cream" replies the unblushing milk
man, "why, the creams at the bottom, OF
course"
Recent investigations have shown that the
cream may be at the bottom" much more
frequently than we are in the habit OF
imagining. A leading dairy paper recently
expressed the opinion, editorially, that ped
ding milk in large city, either by dipping
the amount for each customer from the top
OF a carrying can, or drawing it from the
bottom through faucet, should both be pro-
hlbited by law-with pains and penalties
just as stringent as those that now legally
apply to deliverer of milk to a factory
that has in it less than 8 per cent fat. The
reason given for this opinion was that cream
mounts to the surface OF body of milk
with far more alacrity than many suppose,
and is dipped off to the first few customers
served they get more than their share OF
cream. and the last served get skinned
milk, no matter how goodly may be the IN
tentions, or how vigorous the efforts OF the
distributor. The article in question con-
finn rraAg nj r foof n
business, we tried it for one milk deliverer,
and found there was just about half
as much fat in the last drawn quart as in
the first dipped off,"
This matter was deemed of such import
ance as to be taken up by the agricultural
experiment station of Cornell University.
To determine ust how much variation there
is in the fat of milk served to the different
patrons of route by dipping, member OF
the station staff accompanied a milkman on
his rounds, and as the milk was about to be
served to various patrons took samples for
analysis. The milk was the mixed milk of
herd of native and grade cows. The
dipper, such as is ordinarily used by milk
men, was provided with long handle, SO
that it rested on the bottom of the can when
not in use. The milk was not stirred ex-
cept by the motion of the wagon and the
raising of the dipper. Twelve sam
Piles were taken. and it was found that the
samples in three of the cans were practically
identical in quality, and thar while there
was much variation in the samples taken
from fourth can, much the richest one of
all was taken from the bottom of the can.
A second trial served simply to confirm the
results of the first, and the satisfactory con-
clusion arrived at was that where milk is
peddled by dipping from the can with an
ordinary dipper and where no stirring is
done except by the motion of the wagon and
the raising Of the dipper, substantial justice
is done all the patrons so far as the amount
OF fat apportioned 70 each is concerned.
