apricot tree soon dies from its effects.
No orchard is therefore safe II this
disease Is allowed to run It's course
unchecked In the apple the disease
does not spread so rapidly, being gem
orally confined to the small twigs and
fruit spurs, and Is often spoken OF as
twig blight.
on account Of the germs being deep
in the bark and camblum, and not on
the leaves or exposed parts, spraying
with p0isons OF other mixtures is prac-
tically useless. The only cure 50 far
discovered seems TO be TO cut off ana
burn the diseased parts and so stop the
spread of the germs. The branches
removed should never be allowed to
remain IN the orchard but should al
ways be burned, In cutting off the
blighted limbs, the cut should be made
Il foot below the lowest signs OF the
disease As there is great danger
I'm cutting off diseased limbs OF IN
oculatng the cut on the healthy parts,
and thus spreading the contagion, the
saw or knife should be disinrected
after every cut For this uurpose II Is
commended that the pruner carry

diseased twigs Left contain enough
germs TO KIN n whole orchard. For
| this reason the blight should be cut out

can be controlled, The germ Ia not
affected by the freezing Of winter, but
passes over to the next spring In IN"

Il. S. department Of agriculture, In
his late bulletin on tree pruning
I'm addition 10 modifying the form
Of tree by pruning, another and
equally as important factor can be
controlled by this means. As is well
known the pear ordinarily suffers Sc
Vcrely from the pear blight, but the
work Of Mr.. NJ b. Waite OF the United
states department of agriculture, upon
this disease has fully demonstrated the
possibility OF controlling II by judiclous
methods OF pruning The pear blight
gains entrance 20 the tree IN a majority
OF cases through the flowers, and as
the flowers are borne upon spurs, and
Hs these spurs are developed from
wood which is one or more years old,
frultlng spurs frequently appear upon
| the pear on large branches. II therefore
| becomes evident that II these fruitlng
| spurs are allowed TO remain upon the
| large structural branches Of the tree
| and the blossoms OF such spur become
! affected by the pear blight, the blight

\ 10 the framework branch upon which
| the spur Is situated. In consequence,

! IL the fruting spurs which bear these
! blossoms are kept off the large branches
! Of the tree there is less liability Of in

engaged I'm pear culture should, there

removal of all frulting spurs from the
main structural branches of the pear
tree, This win force the development
OF spurs upon the smaller branches, and
as these can be allowed TO develop at
