STOCK-POISONING PLANTS OP THE EANGE. 35 
In conclusion, it should be stated that, generally speaking, very 
little must be expected from medicinal remedies to reduce the losses 
from poisonous plants. It is true that such remedies will help in the 
case of locoed animals and will save life in the case of larkspur poison- 
ing of cattle. Generally speaking, however, the reliance should be 
placed, not in remedies but upon prevention. Animals must be so well 
cared for that they will not be tempted to eat poisonous plants. Some- 
thing may be done in the way of eradication, as was indicated under 
the discussion of larkspur. Larkspur can doubtless be eradicated 
within a limited area. The locoes in pastures can be eradicated with 
very little difficulty, but upon the open range dependence must be 
placed upon avoidance rather than eradication. Death camas, too, 
does its harm upon the open range, and there it occurs in such large 
masses that eradication is impossible. In the matter of Cicuta, farm- 
ers, without doubt, may accomplish much by digging it up along 
their irrigation ditches, and this practice is usual in a great many 
localities. But in the main the losses from poisonous plants must be 
prevented by careful handling of the herds, remembering always 
that animals are not likely to eat poisonous plants by preference, but 
that under starvation conditions they may be driven to the use of 
such material for forage with most disastrous results.
