by saturating the soil with corrosive sublimate that we have finally 
succeeded in getting rid of the disease. After such a treatment 
we have had no second outbreak. But it takes time to find these 
different places where the disease lurks, and it also takes time to 
get at all the old chronic cases, and that is why the disease still 
continues to reappear. We have had but very few cases in Brook¬ 
lyn, so that it hardly seems we could have exported the disease. 
That is about the status of the matter as it is at present. Eng¬ 
land wants our cattle for several reasons, because of its economy 
among others. This is an important matter to our people, and if 
they can be made to understand the good work which the veteri¬ 
nary surgeon has done for the shippers in this country, the time 
may come when they will fully appreciate it. 
Dr. Weber: I would like to know what is the probability of 
our importing the disease from England to this country ? 
Dr. Salmon : That is putting the shoe on the other foot. Eng¬ 
land, of course, wants to avoid any importation of the disease. 
We hope, of course, that by showing a clean bill of health on this 
side, there is no danger from pleuro-pneumonia by shipping our 
cattle over there. England has a good deal of pleuro-pneumonia 
in Ireland and in Scotland. They have been working on it over 
there for quite a number of years without making much progress. 
At the last session of Parliament they secured a new law which 
transferred authority in cases of pleuro-pneumonia, from the local 
authorities to the general authority in London. Now they hope 
to go ahead and get the disease eradicated. 
We have our quarantines against the cattle from England, and 
will of course maintain them until they show a clean bill of health. 
I do not think there is much probability of importing the disease 
in cattle that come through our quarantine stations, yet, there is a 
bare possibility that the cattle may contain the infection, although 
if our officials are alert it would be almost impossible for the dis¬ 
ease to escape detection. 
I find those who know most about pleuro-pneumonia are the 
most conservative concerning our ability to absolutely wipe out the 
disease. It was said to me by one of the highest officers of the 
British Government that if they succeeded in ridding the country
