As I look at it, the one great secret of a teach er's success is absolute command of his passion, or temper, as we prefer to call it. On no occasion and under no exasperation, or transaction however vexatious, must this even gentleness be relaxed. Unless one is so constituted as to be able to possess himself in absolute patience, he is almost sure to make a miserable failure at teaching, and to make a cur of the dog. More than with any other breed of dogs, kindness, gentleness, and encouraging words and looks are necessary, understood and responded to by the Collie.
