The social prevention for carrying on known degeneracy cannot be too strongly stressed, and hence the first duty of normal parents is to consider the social danger of leaving a feeble-minded child, especially a feeble-minded girl, to any chance of parenthood.

This leads to the question of removal from home of feeble-minded children to permanent custodial care in institutions provided especially for their segregation, possible teaching and thrifty use of small work-power.

Alexander Johnson, who has done so much in the United States to make all philanthropy wise and effective and particularly has helped to form public opinion concerning right methods of care and training of the feeble-minded, tells us that "one-half of the mentally defective can become one-third of a normal person," can be made happy and useful to the extent of considerable aid toward self-support if under constant supervision and given the trained care of special teachers.
There are few private homes in which any feeble-minded boy or girl can attain such a condition.

The children who are "different," if having the sole devotion of father and mother, may be protected and made happy in the measure of their power for happiness.

But if there are other children in the family neither they nor the afflicted one are comfortable.
