london Dec. 23.--It is claimed for
the School Of Agricultural Science at
Cambridge that it has accomplished
greater marvels in recent years than
the famous achievements OF Burbank
in California "A report soon Will pc
issued which is expected to make a
greater sensation In the world OF
science than any other recent discov-
cry.
The line of investigation has been
the study of what is known as Men
delrs law of heredity and its applica-
ton to be demonstrated not only IN
vegetable life but with regard to AMI
mails as well. The principle is best
shown in a simple Illustration. 1t is
found that if dwarf peas and tall peas
are crossed the resulting crop next
year will be all tall peas. The sec
ond wears crop, however, will be the
exact proportion Of one-quarter dwarf
peas and three quarters tall peas.
OF these tall peas just one-quarter
will be pure tall and never again VIII
snow signs OF dwarfness. The re-
naming two-quarters will be impure
INT again when crossed with their like
will give pure tall and pure dwarf
mongrels in due proportion.
1t is affirmed that all quahtles
stransmissible by heredity in vegetable
and animal life are governed by TINS
law. In regard to animals, the SIM
splest and best known case In common
experience is, perhaps, that OF the Dlue
Andalusian fowl II the pure black
and speckled White varieties be mated
together all chickens will be blue An
dalusians and it always happens that
the chickens are of three sorts-some
black. some speckled white, and some
of a composite color known as blue
Andalusian. The most inexplicable tact
in this family picture of inherited
qualities is both blacks and whites,
and also half the descendants are
blues. The next generation may pc
called pure bred-that is, in certain
definite respects, no trace OF a cross
will again appear in their progeny.
This issue proves the existence OF a
deep rooted law that will revolutionlze
the science OF developing varities.
Tho the physical secret is obscure
the course of this strange behavior IN
fowls and peas may be considered Tor
practical purposes. After vast num-
bers of experiments, chiefly with
plants, but also with poultry, mice,
and, other animals, a number OF char-
acteristics, such as the shape OF the
comb in fowls, certain colors IN peas,
beardiness in wheat, and perhaps the
eve color in man, have been marked
down an answering fixed laws which
we can control.
The Mendell law is, of course, by no
means free from complications, and
experiments still are in their infancy.
Still Cambridge biologists have turned
out wheat which combines the strength
of the Manitoba hard grain with the
Weld Of softer English wheats. 1t is
maintained that the value of the Eng
lish wheat crop will be increased oy
this means to the extent of fully $3.50
an acre. This is only one Of the prac-
tical features of the investigation
which shortly will be announced.
The problem of the application of
the Mendell law in breeding animals
and human beings is much more COM
plicated, but it is believed important
discoveries in breeding sheep, cattle,
and perhaps horses already are avail
f able
