Bishoping, an Old Trick.
John C. Knowlson,[1] an old farrier, writing in 1850, says: “Horse dealers have a trick of knocking out the nook teeth at three years and a half, to make a horse appear five years old when only four; but they cannot raise the tusks. At six years old the nook teeth are a little hollow, and at seven there is a black mark, like the end of a ripe bean. Afterwards you will observe the flesh shrink from the teeth, which grow long and yellow. Horse dealers have also a method which they call Bishoping a horse’s mouth; that is, filing the tusks shorter, rounding them at the ends, taking a little out of the nook teeth, so as to make them rather hollow, and then burning them with a hot iron. I was hired by Anthony Johnson, of Wincolmlee, Hull, as farrier to a number of horses that were going to the city of Moscow, in Russia, for sale, and we had a little gray horse, called Peatum, that was seventeen years old, the mouth of which I bishoped, and he passed for six years old, and was the first horse sold, and for £500 English money! I only mention this as a caution to horse buyers.”
