PROF. THORNbER
Horticultural Expert Makes Second
Visit and Lectures on
Peach Culture

The second of Prof. w. S. Thorn
ber's visits to Kennewick in the
series of lectures and discussions ar
ranged by the Highland Improve
ment Club and the Commercial
Club was made last Friday and
Saturday. The lecture on Peach
Culture" Friday evening at the
Commercial Club room and the dis
cussions at the Highland Club house
were largely attended. His recon-
mendations on the conditions OBJ
served during his visits so far were
intensely practical and if followed
should be werth thousands of
dollars to the fruit growers of Ken
newick.
Prof. Thornber's next visit will
be made on Friday and Saturday,
June q and %. The program will
be much the same as it was last
week-visitation Of orchards on
Friday, illustrated lecture on Pear
Culture" Friday evening at the
Commercial Club room, conference
with growers of the Commercial
Club room on Saturday afternoon
and a meeting and discussion at the
Highland Club house on Saturday
evening.
All who own orchards are urged
to avail themselves of the personal
advice which Prof. Thornber will
give for the asking on any question
of culture, pests, proper handling
of fruit, etc., which may arise in
their work. Phone or write to
Kemp X. Dawson or to A. G. Hart
tif you wish the professor to visit
your place.
We publish below a synopsis of
the more important orchard troubles
which Prof. Thornber found during
his last visit, together with his reco-
mendations for their cure:
SUGGESTIONS from the Orchard Inspec-
ton Work
Pear Blight-A peculiar form of
common pear blight was found in
the Winter Bartlett pears. The
trees were very vigorous, thrifty and
had not q heavy crop of fruit, but
the fruit was gradually and rapidly
dropping off at this time. On close
examination it was found that each
pear that dropped was affected with
pear blight; the blight showing up
| in the form of a small black mottling
on a blackened portion OF the fruit.
Upon examination of one of the
trees, hold over patches of blight
we're found on the trunk and the
crotches of the tree. While this
difficulty might remain for years
and not present serious trouble, it
| is apt to develop into malignant
form at almost any time.
/ Treatment-The hold over patch
es should be carefully cut out, re-
moving all diseased or broken parts.
the wound carefully sterilized with
Bichloride Of Mercury Corrosive
sublimate) wash and then after the
wound is dry, it should be carefully
coated with lead paint. All prun-
ings and portions of the bark re-
moved inthe treatment should be
, burned.
:. Crown gall on plum trees-A
nine or ten year-old plum tree was
found in very weakened, dying
condition and upon careful examin-
alton was found that the tree was
badly affected with aphis, which,
, while they might probably weaken
it, would not cause the death oi
a the tree. Upon digging around the
{ tree, We found the trunk almost
completely girdled with crown gall
| This is a disease that effects al
kinds Of perennial plants and while
+ it is not usually considered serious,
it is injurious and is usually very
: difficult condition to treat.
Il Treatment-The best treatment
