STOCK-POISONING PLANTS OF THE RANGE. Ley, 
WHITE LAUREL. 
White laurel (Azalea occidentalis) is illustrated in Plate XXI. It 
is found in the Coast Ranges and the Sierras, growing at a slightly 
lower level than the black laurels, and causes considerable losses of 
sheep. 
RHODODENDRON ALBIFLORUM. 
Rhododendron albiflorum, illustrated in Plate XXII, is common in 
the mountains of the Northwest and has undoubtedly caused some 
losses, although it is not very generally recognized as a poisonous 
plant. Preliminary experiments apparently show that it is more 
poisonous than Menziesia, but less so than the black laurels. 
SYMPTOMS OF LAUREL POISONING. 
The symptoms are practically the same in all cases of laurel poi- 
soning. There is salivation resulting in frothing at the mouth, 
nausea ordinarily accompanied by vomiting, depression, weakness 
shown by a staggering gait or inability to stand, and irregular respi- 
ration. Grinding of the teeth is frequently noticed in sick animals. 
TREATMENT OF LAUREL POISONING. 
Little can be done in the way of remedial treatment. Anything 
that will aid in elimination will be of some benefit, and to this end 
purgatives may be given, such as Epsom salt in doses of 4 ounces. 
The main reliance, however, must be placed on prevention. Herders 
should learn to recognize and avoid the plants. 
FERN. 
_ The common bracken fern, Pteris aquilina, which is illustrated in 
Plate XXIII, should be mentioned here as one of the poisonous 
plants, although the losses from it are probably not large. It has 
long been known abroad that the fern is poisonous to cattle and 
horses. There have been comparatively few reports in this country 
of such losses, and those are largely confined to the Northwest. 
There is no doubt that ferns will poison both cattle and horses, and 
probably sheep, and care should be taken that hungry animals shall 
not have an opportunity to consume any large quantity. 
WILD CHERRY. 
For years there have been persistent reports of poisoning, especially 
of sheep, from eating wild-cherry leaves. There has been great 
difficulty in proving the truth of these stories, for it has frequently 
happened that of several bands going through a mass of wild cherry, 
possibly only one would suffer, while the others would go through in 
an entirely safe manner. A large number of experiments have been
