“ The halves of two snaffle bits (USNM 59.2078, 60.67, fig. 91c; ill. 87) correspond to an item for eight “Bridle Bitts.” (A “snafflebit” costing 1s. 8d. was among Mercer’s purchases for 1743.) A third bit, crudely made of twisted wire attached to odd-sized rings, is a makeshift device probably dating from the 19th century. Three ox chains listed in the inventory are not distinctly in evidence in the artifacts, although a heavy hook, broken at the shank, is of the type used to fasten an ox chain to the yoke (USNM 60.9, ill. 80) . ”
