to try other means of combatting this affection. Prof. Williams 
says: “When the disease breaks out in a herd, the affected ani¬ 
mals are to be isolated, or if in ‘condition,’ slaughtered for beef 
—experience having proved that such beef is good and whole¬ 
some if the animal is killed early in the disease.” 
Dr. Thayer says: “Stamping out is the most effectual and 
economical method of treating pleuro-pneumonia contagiosa.” 
Prof. Law says: “ We do need a short and speedy stamping 
out of the disease in every locality where it has gained a footing. 
All measures which hinder this, whether proposals for investiga¬ 
tion, or the impossible but delusive proposition to examine all our 
cattle while in transit, can but work evil, and only evil, to our 
live stock interests.” 
These views have been largely acted on in many countries. 
Massachusetts has adopted this plan of dealing with the dis¬ 
ease. New York State, and others, are following in her steps. 
Great Britain has attempted “stamping out” for years. Conti¬ 
nental governments did the same till recently, when, owing to the 
progress of science, they have, to a large extent, adopted inocu¬ 
lation. 
Disinfection .— Along with stamping out, thorough disinfec¬ 
tion (by burning sulphur, whitewashing with lime, carbolic acid, 
etc.,) of all sheds and stables must be carried out. 
This thorough stamping out, then, is one course open to us if 
pleuro-pneumonia should appear in Canada. 
But in the second course which was mentioned as a means of 
controlling this plague, viz., Inoculation, we have a policy of pro¬ 
tection which is more effective, more scientific, and which can be 
had at a tithe of the expense of “ stamping out.” 
The use of inoculation as a prophylactic is not new. First 
attempted by Dr. Willems, in Belgium, 1851, it has since come 
into great favor in many parts of the world. 
A Commission appointed by the French Government to test 
and examine the system, reported strongly in its favor. 
It has produced marvellously good results in Australia, South 
Africa and the Continent of Europe. So great are its benefits 
seen to be, that some of the continental governments have made
