158 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 



is not over 3 miles distant from his office, it can be done for $15 on the basis 

 of 25 cows in the herd, and for $20 for 50 to 75 cows in a herd, and for $25 for 

 100 cows in a herd, including the cost of tuberculin, which is about 5 cents 

 per dose. 



If the work was done by a State veterinarian it would then cost whatever 

 his salary per diem was, including what the necessary traveling and hotel 

 expense would amount to. (Borden's Condensed Milk Co., New York, N. Y.) 



As one competent man is required to test a single cow, but can in the same 

 time test 100 cows, it is quite impossible to fix an approximate figure for the 

 expense. (Walker- Gordon Laboratory, Washington, D. C.) 



It depends on number of cattle to be tested and whether test is made by 

 practicing veterinarian or by Government or State officer (25 cents to $5 a 

 head). (Health officer Los Angeles, Cal.) 



The cost of testing is slight; the loss of cattle to the owner may be heavy. 

 (J. M. Houston, White Cross Milk Co., Washington, D. C.) 



Very little (about 50 cents), but besides two days' labor. (Health officer San 

 Francisco, Cal.) 



I do not know. (Health officer Wheeling, W. Va.) 



An experienced man can test as many as 100 head in one night. He should 

 receive approximately $40 for such a night's work. A few animals may be 

 tested for less money, but probably not less than $15 for one animal. The 

 Pennsylvania Live Stock Sanitary Board allows $5 per day and expenses. 

 (Dr. C. J. Marshall, University of Pennsylvania, Philadelphia, Pa.) 



Depends upon conditions whether single animal or herd. (Health officer 

 Scranton, Pa.) 



QUESTION 6. What length of time is required in applying the test? 



ANSWERS. 



The time required for making the tuberculin test is on the average about 24 

 hours, covering parts of two days. (Chief Bureau of Animal Industry.) 



I believe it requires two or three days to test a herd. ( Surgeon General U. S. 

 Army. ) 



Between two and three days. ( Surgeon General U. S. Navy. ) 



Forty-eight hours. (Dr. V. C. Vaughan, Ann Arbor, Mich.) 



Two days for a herd of moderate size (50 to 100). (Dr. William H. Park, 

 New York, N. Y.) 



Twenty-two hours. (Dr. Henry L. Coit, Newark, N. J.) 



Twenty-four hours. Nonreacting animals do not require quite so long. (Dr. 

 M. P. Ravenel, Madison, Wis.) 



Thirty hours. (Dr. T. A. Geddes, Kensington, Md.) 



Test can be completed within 32 hours after the commencement of the work. 

 The temperatures should be taken until at least 20 hours after the injection 

 of the tuberculin. (Health officer, Birmingham, Ala.) 



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



Two days to each herd. (Health officer Cleveland, Ohio.) 



At least 27 hours. (Health officer Cleveland, Ohio.) 



Twenty-four to 36 hours. (Health officer Detroit, Mich.) 



Twenty-four to 48 hours. (State Board of Health, Florida.) 



About 48 hours. (Health officer Jacksonville, Fla.) 



Forty-eight hours. (Health officer Kansas City, Mo.) 



See any authority on the subject. Inject at 6 to 8 p. m., and take tempera- 

 tures until about 2 p. m. on following day. (Health officer Montclair, N. J.) 



Not less than 36 hours. (Health officer Portland, Oreg.) 



Inject tuberculin in evening, and about daylight next day take tempera- 

 tures every 2 hours for 12 to 15 hours. (Health officer Providence, R. I.) 



One to two days. (Health officer Rochester, N. Y.) 



Twenty-four hours. ( Sharon Dairy, District, of Columbia. ) 



One half of each of two days. (Health officer Topeka, Kans.) 



Twenty-four hours. (Sharon Dairy, D. C.) 



Ordinarily the tuberculin test requires about 44 hours after the veterinary 

 has arrived at the farm, but, as above stated, must be repeated after an 

 interval of six months to be complete. (Borden's Condensed Milk Co.. New 

 York, N. Y.)
