craving for
knowledge is satisfied. Somewhere he had come upon some question
touching a campanile or, possibly, _the_ Campanile, as it seemed to
him. Nor would he rest content until I had extracted what the books
have to say on the subject. He had in mind the Campanile at Venice,
not knowing that the one beside the Duomo at Florence is higher than
the one at Venice, and that the Leaning Tower at Pisa is a campanile,
or bell-tower, also. When I told him that one of my friends saw the
Campanile at Venice crumble to a heap of ruins on that Sunday morning
back in 1907, and that another friend had been of the last party to
go to the top of it the evening before, he became quite excited, and
then I knew that I had succeeded in investing the subject with human
interest, and I felt quite the schoolmaster. Nothing of this did I
mention to Brown, for there is no need to exploit the mental
machinery if only you get results.

Many people who travel abroad buy postcards by the score, and seem to
feel that they are the original discoverers of the places which these
cards portray, and yet these very places were the background of much
of their history and geography in the schools. Can it be that their
teachers failed to invest these places with human interest, that they
were but words in a book and not real to them at all? Must I travel
all the way to Yellowstone Park to know a geyser? Alas! in that
case, many of us poor school-teachers must go through life
geyserless. Wondrous tales and oft heard I in my school-days of
glacier, iceberg, canyon, snow-covered mountain, grotto, causeway,
and volcano, but not till I came to Grindelwald did I really know
what a glacier is. There's many a Doubting Thomas in the schools.

CHAPTER IV

PSYCHOLOGICAL

The psychologist is so insistent in proclaiming his doctrine of
negative self-feeling and positive self-feeling that one is impelled
to listen out of curiosity, if nothing else. Then, just as you are
beginning to get a little glimmering as to his meaning, another one
begins to assail your ears with a deal of sesquipedalian English
about the emotion of subjection and the emotion of elation. Just as
I began to think I was getting a grip of the thing a college chap
came in and proceeded to enlighten me by saying that these two
emotions may be generated only by personal relations, and not by
relations of persons and things. I was thinking of my emotion of
subjection in the pr
