eating was difficult. A few of these hogs would live for months, 
only to be finally destroyed by the owner because they were stunted, 
emaciated and valueless. 
Many show symptoms which are not easily differentiated from 
cholera. They become dull, refuse food, have high fever, show 
diarrhoea and die rapidly. The difference is hardly to be appre¬ 
ciated by stockmen and even experts are sometimes confused. In 
a general way, however, hemorrhagic lymph glands, redness of skin 
and red spots on the kidneys will point to cholera, while large areas 
of necrosis, particularly if in the mouth, will point to necrotic 
stomatitis. 
Treatment. 
Treatment is most difficult because the ulcers are not confined 
to the mouth, but extend throughout the digestive tract. Probably 
there is no known medicinal remedy, the administration of which 
is of much value. The removal of well hogs to new quarters with 
thorough disinfection of the premises as described in the previous 
disease, is always to be tried. Young pigs should have their heads 
dippped into a 5 per cent solution of creolin once daily. The sows 
are to be driven through a shallow vat of the same solution in order 
that their teats may be disinfected. The hogs should be kept under 
strict quarantine and after the outbreak is over, a thorough clean¬ 
up of the pens is necessary. All litter should be burned as well as 
all dead hogs, the pens should be white-washed and disinfected. 
LIP AND LEG ULCERATION IN SHEEP. 
History. 
This disease first assumed formidable proportions in Wyom¬ 
ing in 1908 and 1909 and while it has never been a serious disease 
among Colorado sheep, yet it has in the past and is still causing our 
sister state on the north a considerable amount of trouble. For a 
time ah movement of sheep from our feed lots was restricted on ac¬ 
count of this disease, but these restrictions have now been removed. 
While Wyoming has suffered most, we have not entirely escaped. 
Ever since the feeding of sheep, on a large scale, was started 
in Northern Colorado, feeders have been cognizant of a scaly, 
scabby condition of the lips which comes on within a week after 
the animals are placed on feed and usually passes off a week or two 
later without causing any special harm. The following experi¬ 
ment has been reported: 
Sheep were divided into two lots, one of which was placed on 
third cutting alfalfa and beet pulp, and the other on first cutting al-
