putting these bulls with a restricted number of cows, each in a 
small pasture where they would not have had the trying con¬ 
ditions of worrying with other bulls. “ Three others that 
showed signs of relapse were taken away from the cows for ten 
days or more and nursed up, then turned back to service. They 
have been well ever since.” These relapses show that it prob¬ 
ably requires a full season at the south before northern bulls 
acquire that degree of immunity possessed by Southern raised 
animals. Care should therefore be taken during the first season 
to avoid all conditions that tend to lessen the vitality of the 
animal. With proper care but few bulls that have reacted 
from the inoculation will die, and they will usually give good 
service. 
Effects on Reproduction .—No evil effects of inoculation on 
the powers of reproduction have been observed in these experi¬ 
ments. 
Bullock.—“ The bulls have done good service.” 
Rhea.— u All the heifers,” first inoculated, “ produced good 
healthy calves the following spring and another lot appear to 
be pregnant five months after inoculation.” 
Tod.— u The bulls have done good service. I estimate that 
they have sired 200 calves.”
