Abstract: In an effort to minimize injuries to farm animals, and the explicit and implicit costs associated with those injuries, a novel fence identification device which can be easily secured to a fence wire to securely position a flag on the wire is provided. The device comprises a spring wire clamp having a loop at one end and a hook at the other end. The loop end defines a substantially U-shaped brace portion of predetermined length and width. The hook end defines a predetermined acute angle which is sized to pass within the brace portion in tensioned relationship. The flag includes an oversized eyelet aperture and is suspended from the spring wire by the eyelet. The hook end is then passed within the loop end to compress the spring wire and define a gap in which a fence wire is placed. Once released, the tension of the spring wire secures the fence wire between the vortex of the hook end and the U-shaped brace portion.

Abstract: A method of mounting a shed snake skin. The shed snake skin is saturated in water to render it limber and free of folds with at least some foreign particles being removed. The skin is subjected to flowing water to remove the remaining foreign particles. A pool of water is placed on a plastic substrate. The saturated skin is placed on the pool of water, cut longitudinally, flattened on the pool of water and caused to dry to form a unitary structure, with the shed skin adhered to the substrate.
