138 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 



from the Federal Treasury and one-half from the revenues of the 

 District of Columbia. 



31. That, in the judgment of the committee, the scale of com- 

 pensation to owners for cattle condemned as a result of the tuber- 

 culin test, set forth in the order of the District Commissioners dated 

 November 26, 1909, " For the suppression and prevention of tuber- 

 culosis in cattle," which scheme of compensation coincides with the 

 views of the officials of the United States Department of Agricul- 

 ture, be approved as best adapted to insure justice to the herd owner. 



32. While the committee unqualifiedly favors the application of 

 the tuberculin test, it especially recommends that the test be applied 

 gradually, the herds supplying milk to the District being inspected 

 seriatim with such gradualness as may be intelligently calculated to 

 enable the replacement of infected animals with healthy ones, thus 

 avoiding a possible shortage in the District milk supply. For this 

 purpose it is proposed by the committee that a period of approxi- 

 mately two years, or say January 1, 1913, might appropriately and 

 advantageously be fixed for the introduction of the test compulsorily 

 among herds supplying milk for the Washington market. 



33. That milk, from the time of cooling immediately after derived 

 from the cow, until actual delivery at the residence of the consumer, 

 be required to be maintained at a temperature not exceeding 50 F. 

 (provided it be feasible to secure the necessary refrigerator-car serv- 

 ice for transportation from the farm to the city). This requirement, 

 in the judgment of the committee, should be gradually put into 

 force. The maintenance of a temperature not exceeding 50 F. 

 should be required, furthermore, in the handling of cream, and of 

 milk and cream used in the manufacture of butter, cheese, and ice 

 cream. 



34. That the establishment of ice houses on dairy farms for the 

 storage of a sufficient supply to maintain, during the warm season 

 from April 1 (or earlier) to November 1 (or later in exceptional 

 instances of mild weather), milk at a temperature not exceeding 

 50 F., and the installation of an adequate service of refrigerator 

 cars or effectually jacketed cans necessary to maintain a temperature 

 continuously below 50 F., be insisted upon, provided it be deter- 

 mined after detailed examination of items of expense that refriger- 

 ator-car service is a rational economic possibility. 



35. That to meet the restrictions proposed in recommendation num- 

 bered 33, milk be required to be kept refrigerated while on delivery 

 wagons. 



36. That the pasteurization of all milk, not " certified " or " in- 

 spected " in conformance with the requirements of the classification 

 recommended by the Washington milk conference of 1907, be insisted 

 upon, and that for this purpose it be required that an exposure of 

 the milk uniformly at a temperature of 140 F. (60 C.) continu- 

 ously for a period of 30 minutes (or 145 F. for a period of 20 

 minutes) be enforced, with the understanding that the periods of 

 30 or 20 minutes referred to shall not include the interval during 

 which the milk is attaining the specified temperature. That com- 

 pulsory pasteurization as proposed be arranged to take effect on 

 January 1, 1913. 



37. That what is known as " flash " or " continuous " pasteuriza- 

 tion be not permitted, since it is mechanically impossible to subject
