buildings, and care should be taken that all corners and 

 crevices are reached and cleaned. 



Records of Cars Cleaned. — All employees supervis- 

 ing the work of cleaning and disinfecting cars should be 

 instructed to take the numbers and initials of the cars 

 cleaned and disinfected from the cars and not from the 

 railroad records, and to make a careful check of the same 

 before reporting. When the car reported cleaned and dis- 

 infected is not a live-stock car, the class of car to which it 

 belongs should be clearly indicated, as "box," "gondola." 

 etc. 



FARM-TO-FARM INSPECTION. 



Area to Cover. — Farm-to-farm inspection should cover 

 areas from 3 to 5 miles in radius from infected farms. 

 This order, however, need not be followed literally in such 

 instances where there are natural barriers or boundaries 

 such as rivers, mountains, or forests. On the other hand, 

 when infection has occurred on several places along a fre- 

 quently used public highway, it would be advisable to 

 proceed along this highway and inspect premises for a 

 distance of probably 5 miles. As a general proposition 

 farm-tc-farm inspection should extend to all premises sit- 

 uated in any community where there is reason to believe 

 infection may exist. 



Number of Inspections. — At least two, and frequently 

 four or five systematic inspections should be made of all 

 live stock in the neighborhood of infected premises. The 

 first inspection should commence as soon as the affected 

 herd is discovered, and it should extend for 2 or 3 miles in 

 every direction from the infected premises. Not more 

 than 15 days should intervene between the first and second 

 inspections, and the second inspection should be extended 

 to include all susceptible animals within a radius of 5 

 miles of the infected premises.
