Rag-and-bone man, with horse and cart, once a common sight on British streets. He would call out Rag n' Bone Rag n' Bone and collect just those things and lived off the proceeds he could sell on. They still exist but now use vans and lorries
The most typical reason for clipping is to enable the horse to work comfortably and without undue sweating during the winter months when their coats grow naturally thicker. The clipped horse will be denied his natural protection from winter weather, and will need to be provided with additional protection in the form of both stable and waterproof outdoor rugs, ideally with suitable shelter facilities in his paddock.
