be dipped twice as above indicated, ten days apart, and shall be sub- 

 mitted to inspection before shipment. 



Sheep that are not diseased with scabies, but which have been 

 exposed to the contagion of the disease, may be moved interstate for 

 feeding or stocking purposes after one dipping, or they may be 

 shipped interstate by rail or boat to a recognized slaughtering center 

 for immediate slaughter without dipping. 



Regulation 32. When diseased sheep have been dipped once 

 and are shipped interstate for slaughter in accordance with Regula- 

 tion 31, or when exposed sheep are shipped interstate without dip- 

 ping for immediate slaughter in accordance with Regulation 31, the 

 proper officers of the transportation company shall affix to both sides 

 of each car a durable placard not less than S 1 /^ by 8 inches in size, 

 on which shall be printed with permanent black ink in bold-face 

 letters not less than l 1 /^ inches in height the words dipped scabby 

 sheep, or exposed sheep for slaughter, as the case may be. These 

 placards shall also show the name of the place from which the ship- 

 ment was made, the date of the shipment (which must correspond 

 with the date of the waybills and other papers), the name of the 

 transportation company, and the name of the place of destination. 

 Each of the waybills, conductors' manifests, memoranda, and bills 

 of lading pertaining to such shipments by cars or boats shall have 

 the words dipped scabby sheep or exposed sheep for slaughter, as 

 the case may be, written or stamped upon its face. Whenever such 

 shipments are transferred to another transportation company or into 

 other cars or into other boats, or are rebilled or reconsigned to a point 

 other than the original destination the cars into which said sheep are 

 transferred and the new waybills, conductors' manifests, memoranda, 

 and bills of lading covering such shipments by cars or boats shall be 

 marked as herein specified for cars first carrying said sheep and for 

 the billing, etc., covering the same. If for any reason the placards 

 required by this regulation are removed from the car or are de- 

 stroyed or rendered illegible, they shall be immediately replaced by 

 the transportation company or its agents, the intention being that 

 legible placards shall be maintained on the cars from the time of 

 shipment until they arrive at destination and the disposition of the 

 cars is indicated by an inspector of the Bureau of Animal Industry.
