Today, look at the contrast! We are both helpful and hopeful.

Knowing the cause of the disease, knowing how it is distributed, better able to recognize the early symptoms, better able to cure a very considerable portion of all early cases, we have gradually organized an enthusiastic campaign which is certain to lead to victory.

The figures I have quoted indicate how progressively the mortality is falling.

Only, do not let us be disappointed if this comparatively rapid fall is not steadily maintained in the country at large.

It is a long fight against a strong enemy, and at the lowest estimate it will take several generations before tuberculosis is placed at last, with leprosy and typhus, among the vanquished diseases.
