It hasJI^ Ejitely proved that the cause of this illness is the
Psk. This hasBn shown experimentally in Utah and Texas, and
, doubtless woj4 Je equally true for other localities.
44 tUal[xt^4sual time for the cases to occur is in the spring when
.ik t RIBWr.friven to the summer range. They frequently pass into
1hW'oak', bne so early that the grass has not started, so that there is
little for them to eat except the oak. Many of the animals have come
from dry feed, are greedy for green material, and naturally eat
largely of the young oak leaves. Similar conditions obtain in Texas.
At the time when the shinnery oak begins to put out leaves there is
practically nothing else on the range for the cattle to eat, and by
necessity they devote themselves to it. It has been shown by observa-
tion that they do not eat shinnery by preference, but will take grass
more readily if any is to be found.

OAK NOT NECESSARILY INJURIOUS.

While it has been shown that illness may result from eating oak
brush, it does not follow in all cases. The number of cases of sick-
ness is comparatively small, although in some localities in the early
spring oak leaves are about all that the animal can get to eat. In
the shinnery country the annual loss is estimated at 3 per cent, which
indicates that comparatively few of the cattle suffer from their oak
diet. If the animals feed exclusively or nearly exclusively on oak,
some of them may be affected, but many will go through the season
with no serious harm. It has been found experimentally that if a
small quantity of hay is added to the daily ration, no harm results
from the oak feeding. With a certain quantity of other material
oak may be considered as good forage. As a matter of fact, cattle in
Utah frequently come off the oak ranges in the fall in fine condition.

SYMPTOMS.

Perhaps the most noticeable symptom is the extreme constipation.
The feces are passed infrequently, are dark and hard, consisting at
times largely of mucus, and sometimes are bloody. This condition
of constipation may be followed by diarrhea.
The animal becomes gaunt, its coat rough, its nose dry and cracked.
The attitude is peculiar, the head being extended forward. Appetite
