Causes Of plant diseases are OF three
classes:
T. Animal parasites. chiefly insects.

CARE AND FEEDING OF HENS FOR
EGGS.
The results Of IL years work AT
the Massachusetts Experiment station
seem to warrant the following state
ments
THE usual home-.riod experiment
Affords doubtful results. ldentlca4
trials often yield different results.
c-Condition powders have little
value. Well kept hens do not need
them. They have no influence on egg
production.
3-Hens fed green cabbage laid
more but poorer eggs than did those
fed dry cut clover rowen; they were
strong favored and poor color
4-The presence Of a male hira did
mot Influence the number Of eggs but
reemed to increase their weight,
5-Vegetable protein proved Infer
Tor to animal protein. Meat meal
produced many more eggs than soy
bean meal.
s-When fresh cut green bone was
substituted for dry animal foods d.
eestive difficulties were more com
mon Egg production was unchanged
As between corn and wheat 36
trials showed 0.25 cent and o.33 cent
respectively per day: o.sS cent and
1,O5 cent respectively per egg; while
the daily egg production per 100 hens
slightly favored corn.
Authorization tends to favor the
omen air house rather than the glas:
front house. The hens prefer it ant
Law better when thus housed.

DISEASE RESISTANCE OF POTA-
TOES.
Disease Resistance. A term used t
designate certain qualities In a plan
which makes it less susceptible I
injury from fungous diseases.
Types of Resistance. Cd Vine. g
Tuber.
Characters which make for Rests
lance. q A stiff upright woody stem
90 small firm stellatc or hair
leaves; 90 physiological differences !
cell protoplasm or cell structure.
Station Investigations. Studies /
disease resistance were first under
taken in 1903. They include:
"a study of the relative diseas
resistant qualities Of European an
American varieties.
(2) The crossing OF promising va
rieties and the growing Of seedlings
go Selection OF tubers from RESTS
tant plants.
90 Tubcr resistance 10 rot
60 Tuber resistance to scab.
RESULTS OF INVESTIGATIONS.
Studies thus far have shown:
% That no varieties are absolute
immune to disease
(2) That some varieties possess
considerable degree Of resistance.
CD That most Of the disease rest
tant varieties are no. desirable +
commercial purposes.
% That vine resistance Is genera
~ associated with marked tuber r
sistance to rot, but not always So
co. That tuber resistance to rot
not always correlated with vine r
sistance.
q rule more resistant to tuber rot tn,
American.
