this State? “Is it one and the same disease from which the hogs are 
dying in the different parts of it? If but one, what are its symptoms, 
post-mortem appearances, nature, and cause? And what are the means 
by which such losses may be diminished or entirely prevented? These 
are the questions which it seemtd most important to answer; they are 
those to which my time has been entirely devoted. 
It was found very difficult to obtain information of localities in which 
the disease existed ; for although requests were made through our news- 
papers for such information, and although, as I have since learned, swine 
were dying largely in every section of the State, I received during the 
whole time but three letters naming such localities. If to this we add 
that a large part of this State is without railroads; that the farms are 
large, and, consequently, the country is thinly settled ; that usually but 
few hogs are kept on each place, it is seen that a great part of the time 
must have been spent in unproductive work in searching out infected 
localities, and, when these were found, in traveling from farm to farm to 
find herds suitable for experiment, or dead animals for examination. 
These facts must explain the small number of experiments which I was 
able to carry out. 
To give a connected view of the subject, and one convenient for refer 
ence, the report is presented under the following headings:

they more equally distributed among all those to which these animals 
are subject ? =a ;

EXTENT OF DISEASE, NUMBER AND PERCENTAGE OF DEATHS. 
North Carolina is a State with a great diversity of soil and climate. 
Jn the western or mountainous part the summers are not excessively 
het nor the winters extremely cold, and, with the exception of river bot- 
toms which are of comparatively small extent, the soil is rolling and 
naturally well drained; the water is good; there is no malaria, and the 
country is rightfully considered a very healthy one. Extending from 
the mountains for two hundred miles eastward is a strip of country much 
of which is not sufficiently rolling for good drainage through the com- 
pact subsoil, and in a large part of which jntermittent fever prevails to
