seen, done and said previous to the rise of their group, and the
laboratory Problem Box. In view of what this group has
accomplished since 1910, with their "problem boxes," their "mazes"
and their millions of "trials by error," expressed in solid pages
of figures, the world of animal lovers is entitled to smile
tolerantly upon the cheerful assumptions of ten years ago.

But let it not at any time be assumed that we are destitute of
problem boxes; for the author has two of his own! One is called
the Great Outdoors, and the other is named the New York Zoological
Park. The first has been in use sixty years, the latter twenty-two
years. Both are today in good working order, but the former is not
quite as good as new.

A Preachment to the Student. In studying the wild-animal mind,
the boundary line between Reality and Dreamland is mighty easy to
cross. He who easily yields to seductive reasoning, and the call
of the wild imagination, soon will become a dreamer of dreams and
a seer of visions of things that never occurred. The temptation to
place upon the simple acts of animals the most complex and far-
fetched interpretations is a trap ever ready for the feet of the
unwary. It is better to see nothing than to see a lot of things
that are not true.

In the study of animals, we have long insisted that _to the open
eye and the thinking brain, truth is stranger than fiction._
But Truth does not always wear her heart upon her sleeve for
zanies to peck at. Unfortunately there are millions of men who go
through the world looking at animals, but not seeing them.
