while the Keith cow was attacked later. The herds of Prebinow 
and O’Toole, and that in Osborne County, were attacked inde¬ 
pendently of any ascertained communication with herds previous¬ 
ly affected. 
In the search for infection, it was discovered that some Here¬ 
ford cattle in Allen County had been imported through Portland, 
Me., and the recent disease in the quarantine there was at once 
invoked as a sourse of infection. But the disease began in 
Keith’s herd on December 23, 1883, while the infected cattle 
were only landed at Portland on February 2, 1884, and were still 
in quarantine there April 15, when I was in Kansas investigating 
this outbreak. The cattle in Allen County were imported early 
last year. 
From these facts it follows that there is no evidence of the 
introduction of any infection into Kansas; that there is no cer¬ 
tainty that infection has been transmitted from herd to herd ; 
that in the one case in which there was a suspicion that a newly- 
purchased cow had introduced the disease, the cow in question 
was attacked later than the other members of the herd ; that in 
some herds a few cattle only suffered; and that on all farms the 
hogs, without exception, escaped. Such an expeiience is utterly 
incompatible with the idea of foot and mouth disease, the conta¬ 
gion of which rarely spares a single member of a herd of cattle 
mingling in the same yard, and is as virulent to pigs as to the 
bovine race. 
ASSUMED INFECTION FROM ANIMAL TO ANIMAL. 
At first the number of animals in one herd which contracted 
the disease in rapid succession naturally aroused suspicion of con¬ 
tagion, and later certain facts were held to demonstrate the same. 
Six cattle placed March 27 in a small yard built in Keith’s corral, 
in company with six cattle with gangrenous limbs, and with access 
to hav like that formerly consumed by the latter, were attacked 
with sore (vesiculated) mouths on the eighth day, and one went 
lame, but Mr. Hamilton says the lameness disappeared when he 
removed some hardened mud from between the hoofs. The tem¬ 
perature of some of these animals rose to 104° Fall. On my ar-
