Chambon Chambon A chambon is a piece of horse tack. It is a strap that runs forward from the bottom of the girth or surcingle, and forks. The forks continue to a ring on either side of the bridle or halter, at the base of the crownpiece. Running through those rings, the forks follow the cheekpieces to the bit. They may attach to the bit or pass through the bit rings and attach to themselves below the horse's neck. A chambon prevents the horse from raising its head beyond a fixed point. Raising the head causes the length of the chambon
Tree girth measurement Measuring midpoint on the slope is the recommended option. Trees with very large girths, such as some of the sequoias growing the western United States, can also pose girth measurement problems. If they are growing on even a gentle slope, if girth is measured at 4.5 feet about where the pith of the tree emerges from the ground, the upside of the tape could easily be below ground level. In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in
