condition had been met once before when Mr. Schillings appeared upon the
scene, a man whose fairness ought to be doubted by none. He came utterly
skeptical, and yet in the course of a week he learned to handle the
horse and received responses regularly. However, since the public had
begun to doubt Mr. Schillings also, another person had to attempt the

and he could never assist in any tests, until he had been cleared of the
suspicion of having descended to the use of tricks. If it should take
weeks to accustom the horse to a new questioner, there would be
