land to lowland or from the north to the south. The move¬ 
ments may take place in any direction and the results be the 
same. 
In this disease two classes of cattle must be constantly borne 
in mind ; those that have become unsusceptible and those that 
are susceptible. The death record in infected localities indicates 
the presence of infection and of susceptible cattle, and when 
they are raised nearby that the soil and climate which is the 
same for all has no more immediate relation to the disease in 
Florida, than it would have on neighboring farms in New York. 
When spread the disease will break out in either; when con¬ 
fined there will be no outbreak, although the means of spreading 
be close at hand in either. 
Counties and farms in this State and others have been in¬ 
fected and reinfected and are to-day as free from disease as any 
in Maine, though south of, or north of, or east of, or west of 
others, or higher in altitude than others, or lower than others 
and containing more or less bottom lands than others, and grow¬ 
ing more or less pine or oaks than others, and watered by stand¬ 
ing water, running water, etc., etc. 
Further, when outbreaks are closely scrutinized the pestifer¬ 
ous tick is always found. In the murrain counties, Buckingham, 
Patrick, Pittsylvania, Gloucester, Lunenburg or others, cattle- 
ticks abound. When Prince Edward County before the war 
lost her cattle by murrain, the ticks, I am informed, were there. 
Since then they have disappeared and cattle are no longer killed 
by them, excepting as farms are reinfected, as may occur any¬ 
where. 
If, gentlemen, you will ride with me east, west, north or 
south through this State and inspect farm after farm and make 
inquiries you will come to no other conclusion than that this 
disease of many aliases is coincident in distribution with the 
tick, irrespective of altitude, topography, drainage, soil, food, 
verdure or climate. Some or all of these factors may influence 
the spread of the tick, but not the coincidence of the tick and 
the disease.
