THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 157 



In most cases by the Government. Owners should be allowed to pay for the 

 test, if they will have it applied by competent persons. (Dr. C. J. Marshall, 

 University of Pennsylvania, Philadelphia, Pa.) 



Government. (Health officer Scranton, Pa.) 



QUESTION 5. What is the approximate expense of applying the tuberculin testt 



ANSWEBS. 



The expense of applying the tuberculin test would vary considerably with 

 the number of cows in each herd, the distances separating herds, etc. In case 

 the testing is not done by the Government without charge, as above suggested, 

 it could probably be done at an average cost of about $1 per cow. (Chief 

 Bureau of Animal Industry. ) 



I have no exact information on this subject but the process is a simple one 

 and should be inexpensive. ( Surgeon General U. S. Army. ) 



Must vary under a variety of conditions. (Surgeon General U. S. Navy.) 



Slight, if done in large numbers and by suitable persons. (Dr. S. C. Pres- 

 cott, Boston, Mass.) 



At private tests, when in numbers, about $1 per head. (Dr. William H. 

 Park, New York, N. Y.) 



The expense depends upon the size of the herd ; it costs as much to test two 

 cows as a dozen. The expense is chiefly in the time of the veterinarians. 

 (Dr. Henry L. Coit, Newark, N. J.) 



Varies with size of herd. (Dr. R. G. Freeman, New York, N. Y.) 



Depends on size of herd and thickness of population. Should not exceed 

 50 cents per head ordinarily. 



On our results of herds of about 50 cows the expense of the test would cost 

 approximately 44 cents per animal. Larger herds the expense would be largely 

 reduced, while there would be an increase on smaller herds. (Health officer 

 Birmingham, Ala.) 



Two dollars. (Health officer Bismarck, N. Dak.) 



Depends on local conditions and customs. (Health officer Cleveland, Ohio.) 



About $1 per capita. (Health officer Columbus, Ohio.) 



Depends on herd, location, etc. (Health officer Detroit, Mich.) 



Depends upon size of herd. Average herd of 30 cows, from 50 cents to 

 $1. (Health officer Kansas City, Mo.) 



When the herd reaches 30 or more the actual expense per cow is little. One 

 herd of 150 cows in Lynchburg had only one reaction, a fine Jersey. On kill- 

 ing, one lung was sadly affected. (Health officer Lynchburg, Va.) 



Depends on the size of the herd. It will take a veterinarian the best part 

 of a day to test a herd, whether of 10 or 50 cows. (Health officer Mont- 

 clair, N. J,) 



Governed by conditions; large herds can be tested at relatively less expense 

 than small ones; that is, it takes as much time to test 20 cows as it does 50. 

 (Health officer Portland, Oreg.) 



Depends upon the number of cows in herd and distance farms are apart. 

 (Health officer Providence, R. I.) 



Depends on what is meant by this question. If mere cost of injection and 

 passing or reaction, cost for large herds should be light per cow. If " apply- 

 ing test " includes doing away with reacting animals, cost is very great, and 

 for all cows supplying a city the cost is enormous to somebody. (Health 

 officer Richmond, Va.) 



Very small, depending on size of herds. (Health officer Rochester, N. Y.) 



It costs the department $5 per day for our veterinarian, $3 for a helper, and 

 9 cents a dose for tuberculin. If one cow only was tested, you could cut out, 

 of course, the helper. The cost for testing a herd would be nothing like this. 

 (Health officer Seattle, Wash.) 



Depending on size of herds. A large herd can be tested as easily as a small 

 one, and if the work be systematized one herd a day could be tested at expense 

 of, say, $5. (Health officer Topeka, Kans.) 



It depends much upon the size of the herd. A herd of 50 cows can be tuber- 

 culin tested as cheap as 1 cow. The only additional expense, the amount of 

 tuberculin used. (Sharon Dairy, District of Columbia.) 



It is practically impossible to make any suggestion as to the approximate 

 expense, unless the conditions under which it is to be applied are given. In 

 general, however, if the work is done by a veterinary practitioner and the herd
