I have enforced the law against killing certain animals and many others, but the greatest progress of righteousness among men comes from the exhortation in favor of non-injury to life and abstention from killing living beings.
No use to shout at them to pay attention.
If the situations, the materials, the problems before the child do not interest him, his attention will slip off to what does interest him, and no amount of exhortation of threats will bring it back.
Extension work is not exhortation. Nor is it exploitation of the people, or advertising of an institution, or publicity work for securing students. It is a plain, earnest, and continuous effort to meet the needs of the people on their own farms and in the localities.
