    taken tuberculosis may enter a herd. All the reasons for this may not have been disclosed. A tuberculous cow, or one that has been exposed to the disease and is sLill in the incubative period, may, for instance, fail to respond to the test, and may be the means of infect- ing the herd if there be not a rotesting within reasonable time. All the animals in a herd must be retested at intervals of not more than a year. To maintain a large dairy herd free from tuberculosis is a very expensive procedure, and, therefore, one rarely undertaken. It is not merely the cost of the tuberculin, for this is a small item. The great expense is in discarding cows apparently in good health, often produc- ing a large flow of milk, to which most people would take no excep- tion. But as long as there is a possibility that the milk of such cows may be injurious, it is felt to be necessary that guaranteed milk should be above the slightest suspicion, so that people who buy such milk shall obtain milk which is beyond question pure and safe. The herd maintained by the Walker-Gordon Company, at Plains- boro, New Jersey, was collected after the tuberculin test was estab- lished. This test has been employed at every step in the enlargement and development of the herd. Notwithstanding that all other sani- tary conditions are maintained, every animal in the herd and every new-comer has been tested and retested in the manner indicated ; and no milk of a suspected animal is used. The following are Dr. Mar- shall's regulations: 1. All cows added to the herd must be free from tuberculosis or other disease as shown by physical examination and tuberculin test. A test to be valid must be applied within the month before the time the cow is brought to the farm. The test may be applied by any veterinarian in good professional standing. It is to be made as follows: The normal temperature shall be established by at least two prelimi- nary measurements made not less than two hours apart, and one shall be made before tuberculin is administered. No cow shall be tested that has a temperature above 103° F. The tuberculin shall be adminis- tered in the evening. At least three temperature measurements shall be made after tuberculin is injected, covering the period from the ninth to the sixteenth hour after injection. It is required that a full report on the inspection and test shall be sent to the superintendent of the farm. This report shall include a full and accurate description of each cow so that she may be identified and correlated with the report on her test. 2. All cattle shall be tagged when brought to the farm so that they may be identified, and a careful record shall be kept showing the facts
