no
alternative but to wait that length of time.

A happy circumstance helped us out of our difficulty. We had chanced in
our discussion to mention the experience of Dr. Miessner, a member of
the commission, who on the day before had gone to witness an exhibition
of the mare "Clever Rosa", and who believed that he had succeeded in
discovering the tricks involved. There was a sudden change in Mr. von
Osten's attitude. He expressed his willingness to undergo the most
stringent examination and agreed to anything in the way of conditions of
control, challenging even the proven ability of Dr. Miessner. "I have
neither whip nor rod, as had the man in the exhibition, and agree to any
precautionary measures you may care to take."

After he had gone, the commission decided to ask him to have the horse
perform one of the more common, simple, feats. They were going to watch
him very closely. Different members were assigned the task of attending
to different parts of his body (head, eyes, right hand, left hand, etc.)
while Mr. Busch, since he was the most proficient in the detection of
tricks, was to regard the total behavior of the man.

The exhibitions included the indication of the day of the week by means
of taps, the day just past, the day ahead, its date, arithmetical
problems, and the counting of rings strung upon a rod. Messrs. Grabow
and Hahn interpolated a few tests themselves, in which they did the
questioning. All tests were successful.

Mr. von Osten withdrew, and in comparison of notes which followed, Mr.
Busch, as well as all the others, declared that they had discovered
nothing of the nature of a visible sign. Mr. Busch said that he had also
kept an eye on the spectators and had noticed nothing there.
Nevertheless, he desired to see Mr. von Osten go through one series with
no one else but himself (Busch) present.

This was done, and on this occasion a number of tests were made in the
recognition of colored cloths. The horse was required to indicate, by
tapping, the place in the series which the cloth occupied and was then
asked to bring the green or the red, as the case might be, in his mouth.
Furthermore, he was asked to approach that one of the five gentlemen
standing at a distance, whose photograph had been shown him. Then he was
requested to spell the words "Rat" and "Busch" according to the method
which he had been taught. Nearly all of these tests were likewise
successful.
