are many who, from self-interest or
interest in the cause, work regularly from ten to sixteen hours.

Would it help to punish employees for working in unhealthy places? The
highest service that can be rendered industrial hygiene is to educate
the industrial classes to recognize hygienic evils and to cooeperate
with other citizens in securing the enforcement of health rights.

CHAPTER XXIV

THE LAST DAYS OF TUBERCULOSIS

If the historian Lecky was right in saying that the greatest triumphs of
the nineteenth century were its sanitary achievements, the Lecky of the
twenty-first century will probably honor our generation not for its
electricity, its trusts, and its scientific research, but for its
crusade against the white plague and for its recognition of health
rights. Thanks to committees for the prevention of tuberculosis,--local,
state, national, international,--we are fast approaching the time when
every parent, teacher, employer, landlord, worker, will see in
tuberculosis a personal enemy,--a menace to his fireside, his income,
and his freedom. Just as this nation could not exist half slave, half
free, we of one mind now affirm that equal opportunity cannot exist
where one death in ten is from a single preventable disease.[13]

Of no obstacle to efficient living is it more true than of
tuberculosis, that the remedy depends upon enforcing rather than upon
making law, upon practice rather than upon precept, upon health habits
rather than upon medical remedies, upon cooeperation of lay citizens
rather than upon medical science or isolated individual effort. Without
learning another fact about tuberculosis, we can stamp it out if we
will but apply, and see that officers of health apply, lessons of
cleanliness and natural living already known to us.

Perhaps the most striking results yet obtained in combating
tuberculosis are those of the Massachusetts General Hospital in Boston.
To visit its tuberculosis classes reminds one more of the sociable than
the clinic. In fact, one wonders whether the milk diet and the rest
cure or the effervescing optimism and good cheer of the physicians and
nurses should be credited with the marvelous cures. The first part of
the hour is given to writing on the blackboard the number of hours that
the class members spent out of doors the preceding week. So great
