They are not to be used on a horse that is standing in a stall (though this is a very common type of misuse), nor are they used while riding. However, the surcingle and side reins are used as safety tools in the sport
Tree girth measurement if a tree branches below breast height, that the girth of the largest branch should be measured at breast height ignoring the other branches. However, if a good portion of the trunk volume or cross-sectional area has been split from the total by measuring above a significant branching, then this is not giving a full and fair measure of the trunk's girth. If the pith of the branch does not intersect the pith of the main trunk above ground level, it is not a branch but a separate trunk and this tree should be considered a multi-trunk tree. If the
