QUARANTINE AND TRANSPORTATION. 223 



ing 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 boats, or are 

 rebilled or reconsigned to a point other than the original 

 destination the cars or boats into which said sheep are trans- 

 ferred and the new waybills, conductors' manifests, memo- 

 randa, and bills of lading covering such shipments by cars 

 or boats shall be marked as herein specified for cars or boats 

 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 boat or are destroyed 

 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 or 

 boats from the time of shipment until they arrive at destination, 

 and the disposition of the cars or boats is indicated by an 

 inspector of the Bureau of Animal Industry. 



PERMITTED DIPS. 



SECTION 5. Paragraph 1. The dip at present permitted by 

 the department for the treatment under official supervision 

 of sheep affected with or exposed to scabies is the lime-sul- 

 phur dip made in the proportion of 8 pounds of unslaked lime 

 (or 11 pounds of commercial hydrated lime not air-slaked 

 lime) and 24 pounds of flowers of sulphur to 100 gallons of 

 water. The dipping bath should be used at a temperature 

 of 100 to 105 F., and must at all times be maintained at a 

 strength of not less than iy 2 per cent of "sulphid sulphur," 

 as indicated by the Bureau of Animal Industry field test for 

 lime-sulphur baths. 



Paragraph 2. A proprietary brand of lime-sulphur solution 

 may be used in official dipping only after specific permission 

 therefor has been issued by the Bureau of Animal Industry. 

 No dip other than the lime-sulphur dip will hereafter be given 

 department permission for use in the official dipping of sheep 

 for scabies unless it has been shown to the satisfaction of 

 the Bureau of Animal Industry (1) that the strength of the 

 bath prepared therefrom may be satisfactorily determined in 

 the field by a practical portable testing outfit; (2) that, under 

 actual field conditions, the dipping of sheep in a bath of def- 

 inite strength will effectually eradicate scabies infection with- 

 out injury to the animals dipped. 



LOSSES FROM DIPPING. 



SECTION 6. The dipping shall be done carefully and the 

 sheep handled as humanely as possible. The department dis- 

 claims responsibility for any loss or damage resulting from 

 dipping, and those who wish to avoid any risks that may be 

 incident to dipping at the stockyards, as well as to avoid 

 liability to prosecution, should see that their sheep are free 

 from disease before shipping them to market.
