extent in the northeastern part of the state. The state experi¬ 
ment station is still carrying on experiments with this disease. 
“ Scabies in Cattle —This parasitic disease is generally being 
eradicated. Last fall the cattle were in fine condition and they 
have stood the severe weather without much loss. A few out-

breaks occurred in a non-quarantined. area. We have employed 
a man for the last two months especially for the purpose of look¬

different parts of the state. These cases are looked after as soon 
as reported and held under quarantine until the sheep are dipped. 
Ulcerative Ano-Vulvitis in Cattle —We have had only a 
few outbreaks of this disease during the past year. In one herd

“A New Disease in Horses —Last fall a great number of 
horse owners from several counties in the western part of the 
state reported to this office that they have a new disease affecting 
hundreds of horses in their community. The description of the 
disease in all of these reports is identical: Swelling of the breast 
with formation of large abscess which would rupture and dis¬ 
charge a considerable amount of thick creamy pus. These ab¬ 
scesses would sometimes form on other parts of the body. This 
affection was found quite prevalent in horses all over the western 
part of the state. Some invstigations were carried on by the de¬ 
partment of animal pathology of the station. As yet there is no 
report.”

localities mares.
