grain of strychnin. By this treatment cattle can be cured and put in
condition for market.

WHITE SNAKEROOT (EUPATORIUM URTICAEFOLIUM).

White snakeroot, frequently known as "rich weed," is a plant growing in
great abundance in some of the eastern and central regions of the United
States. It is particularly abundant in parts of Ohio, Indiana, and
Illinois, and in western North Carolina. It is responsible for most, if not
all, of the cases of a disease which is commonly known as "milk sickness."

_Symptoms._--The animals are constipated, sometimes have bloody feces,
become weak, and exhibit muscular trembling. This trembling is very
characteristic, so that the disease is sometimes known as "the trembles."

_Remedy._--There are no remedies which will work very efficiently. It is
desirable to give the animals purgatives like Epsom salt and, of course, to
remove them from fields where this plant is abundant.

RAYLESS GOLDENROD (ISOCOMA WRIGHTII).

The rayless goldenrod is a plant growing in especial abundance in parts of
the Pecos Valley in New Mexico and Arizona, and there produces a disease so
much like that produced in the East by white snakeroot that it is sometimes
called milk sickness. More generally this disease goes under the name of
"alkali disease." The plant has produced heavy losses in the regions where
it grows abundantly.

_Symptoms._--The symptoms are much like those produced by the white
snakeroot. The animals are constipated, sometimes have bloody feces, become
weak, and exhibit muscular trembling. There is good reason to think, too,
that the milk of cows eating this plant is more or less injurious.

_Treatment._--A purgative like Epsom salt will aid an animal in recovering,
but most important is to remove the cattle from pastures where the plant is
abundant and give them an abundance of good forage. Under such conditions
they are almost certain to recover.

MILKWEEDS.

Many of the milkweeds have long been known to have more or less poisonous
properties. Within the last few years it has been discovered that certain
of the milkweeds going under the popular name of whorled milkweeds are
especially toxic. There are at least four species of whorled milkweeds, but
two of them are particularly important from the standpoint of people
handling livestock. One, known scientifically as _Asclepias galioides_, is
harmful in Colorado, Utah, Arizona, and New Mexico, while another, known as
_Asclepias mexi
