I have described the causes which, by general admission, have led to the almost complete failure of the Sarda Act and of previous efforts to control child marriage. But the root cause of all these specific reasons for failure is plainly this: that there have not been people in sufficient numbers caring sufficiently to insist that "this thing must stop," and to back their resolution by the kind of prolonged, well-thought-out, extensive and intensive effort which, as every experienced reformer knows, alone suffices to bring about the destruction of any evil which is deeply rooted in the customs of great masses of people.
