mum expense. ‘This method is the well known method of 
Prof. Bang, developed in Copenhagen, and now extending 
itself over Europe. It is universally spoken of in high terms 
by bacteriologists and veterinarians who know anything 
about its results. They recommend it as the only feasible 
method yet devised for meeting the problem. The object of 
the method is to enable the owner of a herd of cattle infected 
with tuberculosis to obtain a healthy herd without subjecting 
himself to much of any expense, and with a minimum of in- 
convenience. ‘The general method is well known, but a de- 
scription of its application may not be out of place here. The 
method of Prof. Bang is as follows: 
I. ‘lhe farmer consents to follow out accurately directions 
given him by the veterinarian. ‘This is a primal necessity, be- 
cause if the directions are not followed out with strict accuracy 
the whole plan is absolutely useless. 
2. After the farmer has consented to the proper ‘condi- 
tions, the whole herd is tested with tuberculin and then the 
animals separated into three sections. 
3. The first section contains those that neither show clin- 
ical signs of tuberculosis nor react to tuberculin. These are 
presumably healthy and are put into a barn by themselves. 
This barn must, if previously occupied, be disinfected before 
the healthy animals are put into it. 
4. The second section contains those that show clinical 
symptoms of the disease such as to indicate an advanced case 
of tuberculosis or such as show tuberculosis in the udders. 
These animals are slaughtered at once, submitted to proper 
inspection and the flesh used or destroyed in accordance with 
the verdict of the inspectors. 
5. The third lot contains the animals that are apparently 
healthy, with no external signs of tuberculosis, but that have 
reacted to the tuberculin test. These are presumably animals 
with incipient tuberculosis. They are put in a separate barn 
and kept absolutely isolated from the healthy herd. 
The isolation of these two lots of animals from each other 
must be absolute, though it is not necessary that they should 
be in separate buildings. In the barn where the first experi- 
ments were made there was a long cattle barn with some two 
hundred animals in it. After the inoculation a partition was 
built in the barn separating it into two divisions, in one of 
which were kept the healthy, and in the other the reacting, ani- 
mals, This partition absolutely separated the two herds from
