The bulletins brought home by precept

an side to the question-that of danger
thru the infection of mlk-but the
proof of that is a matter of advanced
bacteriology. The bulletin, having no
room for subtleties, kept the loud pedal
down on the economic side of the ques-
ton.
The experiment station force follow
ed up their literature in person, making
an opening for instruction out of every
opportunity to address an institute, a

Their most fruitful field for conversions
was, however, among the students of
the agricultural college. which has a

to reach a fraction, and only possible
to convince fraction of a fraction,
thru the medium of literature alone.
Before a bulletin could get results, it
had to overcome not only a resistant
skepticism but a good deal of strong
delusion as to the nature of the dis
ease, that had come down from the
days when tuberculosis was vaguely
supposed to be the joint result OF
incredibly and cold draft. Even where
the printed page carried conviction, it
was hardly a gripping enough form
OF appeal TO rouse a man ITO enlist in an
active sanitary campaign. There was
need for new departure in the educa-

In 1906 DIR. Russell, in alliance with
DIR. Roberts of the state sanitary board
introduced a novelty into the campaign
They started a statewide series OF
