 this bone begins to flatten and grow sharper on the edge, 

 until you find it in a very old horse as sharp as the back 

 of a knife blade. Now a careful and experienced hand 

 in this matter can tell the age of any horse by feeling, 

 with his eyes closed, certainly within two or three years, 

 and some will not vary over one year in going over a 

 dozen horses.
