Bleeding PEAR Trees
There are many diseases of trees and
shrubs of which those who cultivate them
take but little account. and consequently
know but little. We are not obseryant
enough. The man who cultivates trees, and
the success of whose business depends upon
the health and productveness of those trees,
should make their study matter Of every
day life. He should be daily on the lookout
for any popularity noticeable in their ap-
pearance, and should BE- as familiar with all
their ailings as should a physician with the
constitution and SYMPTOMS of his patients.
Practical cultigators are apt TO refer ali such
matters to scientists, when they should them.
selves become the scientists. Science with
reference to any particular branch OF nature
is after all but On accumulation of facts and
differences obtained by observation and rea-
soning from these facts. The practical man
in any branch of culture, as agriculture, hor-
ticulture or vitioul;gre. should above all
Others be the closest and most con
slant observer and best reasoner, and
consequently the best scientist. The
difficulty with our general farmers, or
chardists and vine-growers is that they are
frightened at the thought of science They
imagine that the man Of science has sort
of charmed life; that he has some super
natural mode of obtaining knowledge ; that
he travels road hedsed about TO keep away
the common people. Now, the plain truth
is that there is 10 such charmed life, no such
hedged road, and that men who become noted
as great naturalists and scientists are those
who begin life by seeing and Studying what
nature spreads out before al alike. Above
all others. the farmer has to deal with nature
most and is the most dependent on nature
for his business success. Should he not,
therefore, he the best and closest observer Of
nature and the best naturalist, SO fsr as re-
latss TO his particular branch Of agriculture
We have made these general remarks As in.
troductory TO our main obj ct, which is to
call attention Of horticultur:st to me bleed
ing pear trees that have been noticed IN an
orchird in this vicinity. There are three
trees in the orchard Of John Cox, President
OF the County Board of Horticulture Of Sac
ramento county, located near Sutterville,
that are afflicted with some disease that

The disease made it, appearance first about a
year ago on tree from which the branches
had been cub for grating the year previous.
Tie cioDs then put int the tree started and
made an ordinary growth the first summer,

Cox noticed that lst below the limbs the sap
was exudine, the tree bleeding. The sap

and ran down to the ground. scaijing and
killing tie bark in stresks over which it ran.
This process continued during the season, the
tree giving s. mptdu Of gradually losing its
vigor and life. This spring che tree failed to
show signs Of life, ana has been dug up and
burned, aud now the two adj Dining pear trees,
one on each side of the dead tree,
are affected in q similar manner

sap. is coming ont through the bark of the
present sick trees near tie ground, but IN;
the same appearance of effervescirg as in the
original tree. Wherever the sap runs down
on the outside It seems to poison the bark al

noticed that there is no deposit of new WOOD
or albumin, and both wood aud bark were
dead and dark colored. We would be glad il
any of our horticultural readers have had
similar experience that they would let III
hear from them, and also if they can give.
