Meadows infested with Ergot should not be cut for hay 
or pastured after sclerotia have formed. By cutting 
early, while the grass is in flower, the spread 
of the disease can be checked. Wholesome 
hay will also be obtained by this procedure.

FORAGE POISONING. 
There have been very severe losses from forage pois- 
oning in various parts of this continent, but although 
much painstaking work has been done to 
determine the cause of the disease, the 
results have been conflicting and unsatis- 
factory. Horses and mules are the animals chiefly at- 
tacked, the disease following the feeding of mouldy silage, 
spoiled hay, or immature mouldy corn. Cattle, sheep, 
pigs and poultry are apparently very resistant if not 
immune. 
Many have considered that the disease is due to poisons 
secreted by moulds on the feed. Several species of mould 
grow commonly on corn and hay and a great deal 
of work has been done with a view to determin- 
ing the particular one responsible. Efforts toward this 
end have not been successful. From experience with 
numerous cases of poisoning, evidence against a certain 
mould or group of moulds has been built up. Later,
