Use "markhoor" in a sentence
"My brother has done a good deal of ibex, mountain sheep, and markhoor shooting in Cashmere and Thibet, and I suppose the sport to be had among the tremendous mountain masses of the Himalayas must stand above all other kinds of hill shooting; yet, after all, it is hard to believe that it can yield much more pleasure than that felt by the American hunter when he follows the lordly elk and the grizzly among the timbered slopes of the Rockies, or the big-horn and the white-fleeced, jet-horned antelope-goat over their towering and barren peaks."
