I heard of one case where, day after day,
the lecturer's audience consisted of three students - and always
the same three. But one day two of them remained away.
The lecturer began as usual -
"Gentlemen," - then, without a smile, he corrected himself,
saying -
"Sir," - and went on with his discourse.
It is said that the vast majority of the Heidelberg students
are hard workers, and make the most of their opportunities;
that they have no surplus means to spend in dissipation,
and no time to spare for frolicking. One lecture follows
right on the heels of another, with very little time
for the student to get out of one hall and into the next;
but the industrious ones manage it by going on a trot.
The professors assist them in the saving of their time
by being promptly in their little boxed-up pulpits when the
hours strike, and as promptly out again when the hour finishes.
I entered an empty lecture-room one day just before the
clock struck. The place had simple, unpainted pine desks
and benches for about two hundred persons.
