FLOCK HUSBANDRY IN WESTERN STATES 247 



out during the feeding season, is ruinous and will 

 entail great loss unless promptly suppressed. The 

 longer dipping is delayed the more costly it is be- 

 cause of the greater amount of material required, 

 because of the greater degree of exposure when the 

 weather is colder, and because the animal after 

 being on feed suffers a greater shock and has a 

 worse set-back than when dipped on its arrival at 

 the feedyard. 



Lambs that are sent out from the larger centers 

 of distribution, such as Chicago, Omaha and Kansas 

 City, are dipped under Federal supervision before 

 they leave the yards. This dipping should preclude 

 the necessity of further dipping at home unless in 

 the case of very well-advanced cases of scab. Such 

 instances of diseased sheep are much less numerous 

 than they once were, thanks to a rather determined 

 scab campaign by flock-owners on the ranges. The 

 dipping at the Chicago yards has for several years 

 been so thorough that the writer has ceased to again 

 dip the lambs received from that place. He feels, 

 however, that he is running considerable risk by this 

 neglect, since it is only a question of time when care- 

 nessness or "graft" will send out again strings of 

 imperfectly dipped lambs from these very yards. 

 This has, at least, been the history of the past. One 

 winter some years ago the writer trusting to the 

 clipping there received had the distressing experi- 

 ence of having to dip every sheep upon the farm in 

 midwinter. 



It is safer then not to rely upon the dipping at
