689. BLACK-FACED, on HEATH-BRED SHEEP.--This is the most hardy of all

our native breeds, and originally came from Ettrick Forest. The face and legs are black, or sometimes mottled, the horns spiral, and on the top of the forehead it has a small round tuft of lighter-coloured wool than on the face; has the muzzle and lips of the same light hue, and what shepherds call a mealy mouth; the eye is full of vivacity and fire, and well open; the body long, round, and firm, and the limbs robust. The wool is thin, coarse, and light. Weight of the quarter, from 10 to 16 lbs.
