of
pernicious curiosity, may eat them with disastrous results. This has
frequently happened when freshly cut branches of cherry, yew, oleander, and
other plants have been thrown where dairy cattle could get at them.

OAKS.

The foliage of oaks is a valuable constituent of the forage on many ranges
and pastures. It has been shown, however, that when this is eaten without
some admixture of other food, cattle frequently sicken and die. Many cases
of the poisoning of cattle by acorns have been reported in England and
Germany, and there have been some complaints in the United States. Harmful
results from eating acorns do not seem likely to occur except as they are
eaten in considerable quantities.

_Symptoms._--The symptoms of oak poisoning are constipation, mucus and
blood in the feces, emaciation, and edema. The symptoms of acorn poisoning
are much the same.

_Treatment._--Change of pasture or an addition of other food material.

HORSE CHESTNUT--BUCKEYE.

All the species of _AEsculus,_ popularly known as horse chestnut or buckeye,
are considered poisonous. The bark, leaves, and fruit are injurious. It is
said that if the fruit is boiled or roasted and washed out it becomes
harmless and even is a desirable addition to the feed of cattle. The
Indians in time of scarcity of food have used the fruit after preparing it
in this way. The buckeyes are said to have a specific effect in producing
abortion in cattle and goats.

DEATH CAMAS (SPECIES OF ZYGADENUS).

The death-camas plants, which are commonly known in the Pacific States as
"lobelia," are especially destructive of sheep, but cattle sometimes eat
them and are poisoned. Cases of cattle poisoning are not likely to result
fatally.

_Symptoms._--The symptoms are salivation, nausea accompanied by vomiting,
great weakness, and lowered temperature.

_Treatment._--There is no effective treatment for death-camas poisoning.

FLY POISON (CHROSPERMA MUSCAETORIUM).

This plant, which is closely related to the death-camas plants, is
sometimes known as "stagger grass" and causes a considerable loss in the
Southern States. It grows earlier than the grasses, and on this account is
more likely to be eaten. Like death camas, it produces pronounced nausea,
resulting in vomiting and weakness, and in cases which recover the effects
may continue for several days. Apparently the injurious effects are more
common in the case of cattle than in other domestic animals. There is
