PREFACE. 
ISEASES of the pigrhave not been hitherto adequately 
represented in veterinary literature as they should have 
been, especially in this country where the growing of pigs is 
one of the principal industries, represented by hundreds of 
thousands of dollars. I have been surprised that some of my 
professional brethren have not taken up this work, but I sup- 
pose that lack of time .and opportunity prevented them from 
so doing. Some ten years ago I was urged by some of my 
friends to undertake such work, but having so little literature 
on the subject to cull from, I hesitated to do so, but since com- 
ing to Illinois I have had ample opportunity of investigating 
all the diseases of swine. e 
The subjects dealt with are based on science and confirmed 
by experience, so that the reader will not lose time in reading 
theories which are not confirmed by facts. There are a few 
diseases of swine, such as thumps, partial paralysis of the hind 
quarters and canker of the mouth, which will in the majority 
of cases prove fatal. These diseases have been thoroughly in- 
vestigated and the proper remedies discovered, and if adminis- 
tered as set forth in this treatise the majority of the affected 
pigs willrecover. I have, with the assistance of Doctor Burrill, 
Professor of Bacteriology in the University of Illinois, investi- 
gated extensively ‘‘hog cholera,” and have made considerable 
headway in treating the disease successfully. These results 
and treatment will be found in this volume. It also contains 
as an introduction an article on the health of the pig which 
will be of great service to the swine breeder. The book con- 
tains a number of illustrations which will be helpful to the 
reader. My hope is that this manual will fill a long felt want 
to the veterinary surgeon and swine grower.
