Fence specifications for muskrat farms as worked out 

 by the Crown Iron Works Company of Minneapolis, Minn. 

 The galvanized sheet-iron strip used at the top of the fence 

 is useful only in keeping muskrats from climbing out but 

 to keep minks and other predatory animals from climbing in. 

 This company has specialized in fence and pen building 

 material for fur farming purposes and issue helpful cir- 

 culars on the subject.
