is 10 kill infested cattle as soon as they are
found to be diseased. 1t is possible to de-
tect tuberculosis before the animal be-
comes dangerous. Then the speaker de-
scribed eggs. The egg of the cow is essen
tiallv like the egg of hen. An egg of any
animal is simply cell. Every animal is
made of a great aggregation of cells. In
lower animals cell can be taken out anC
ii will produce new cell; but in the
higher and more complex animal if cell
is taken out 1t Will die. The cell has an
outer skin which is filled with fluid which
is known as prOtoplasm. The nucleus of
the cell contains the architects plan for
the whole animal From this plan the
whole animal might be built up.
lD the nucleus lies the determining quail
ity. This has been demonstrated by ex-
pertinent with the eggs of the sea urchn.
Theoretically, if the nucleus of a cows
egg could be taken out and substituted for
the nucleus OF a hens egg. within hens
egg, there would be no difficulty, il proper
means of development could be provided,
to produce cows from hens eggs. 81 do
not think that this will lead at once TO a
revolution of the industry" said Mr.. JoT-
dan, while the sembled farmers smiled
''but there is no theoretical difficulty in
the way and fully as wonderful things
have been done"
Mr.. Jordan did not believe that tuber-
culOsis is hereditary, nor is any other dis
ease. More has been found out about
heredity in ten years than was ever known
before. The study of the cells will lead TO
valuable discoveries. The laws of heredity
extend all along the line. What is true of
higher animals is true also of man, and the
same laws extend To fishes and worms.
The next paper read was written by
ID. w. Nelson of the National Dairy
Union Of ElgiD. Ill. The paper was read
by J. 3. Burdell. The author spoke of
the scientific improvement brought about
in the handling Of dairy products by the
organization of dairymen. He also dealt
severely with the competition given by
oieomargarine to the pure product of the
cow. He found that S1,0OO,OO 600 is in
vested in the dairy industry in the United
States. and that the value of the output of
dairies IN this country is $500, 900, 900 an
nually. The frauds through which butter
has been supplanted unjuslly, TO some ex-
tent, by Oleomargarine were described,
and some history OF the origin of oeo-
margarine was given. Butterine sue
ceeded oleomargarine, and it has been put
on the market in large quantities under
the gnise of pure butter. Oleomargaripe
has found protection by decision in the
Federal courts under the wording of the
interstate commerce law. A national or
ganiZa;iOn was formed 10 protect butter
from fraudulent competition, and the
author believes that good will be the out
come. The work of the national organ
iZatl0n is in part to secure the necessary
laws and to secure the enforcement of
existing laws.
John p. Irish amused the delegates for
few minutes with a story about cow
which he milks over in Oakland. In the
estimation of the colonel his animal is the
greatest one OF her kind on earth. Taking
the price of milk In OAKLAND as standard
she must give about 500 worth per year
The afternoon session was resumed at
ID NJ and Q6lnnrnP6 a
of the meeting OF the street-cleaning COM
mittee in the same rooms.
The first paper was read by Professor
Nathaniel Z. Wilson, chemist of the
Nevada experimental station. at Reno.
The subject was ''The Babcock Test and
Its Relation to the Dairy Interests" This
paper was somewhat historical, beginning
with the story of the oil test and following
up coDsecutively the story of the various
tests preceding The Babcock test. DIR. S
M. Babcock in 1889 inven ted the test which
bears his name. he was connected with
the Wisconsin experimental station at the
| time. The speaker related the resnIt of
| various tests under the Babcock method IN

| for butter-making. 1t has bsen common
opinion that the milk is richest which pro-
! duces most cream. Chemical analvsis
demonstrates that other milk NAV ne
richer in the capacity for producing butter
lat. which IS the essential for butter-mak-
ing. The speaker described the processes
used in making tests under the Babcock
| SYSTEM using apparatus to illustrate his
meaning.
! Professor Wlrkson of Berkeley gave a
talk on New forage plants for dry lands"
Mr.. Wlckson brought with him a number
| OF specimens of plants which the university
authorities had been experimenting with.
! They had been collected from ali paris of
| the world.
! The first sample which he exhibited was
the California prairie grass. This plant
has an interesting history. When the
university was in search of grasses adapted
| to dry climates it discovered that in
