The farm and the village have a considerable amount of routine work which can be done by these sub-normal people and they therefore have opportunity to maintain themselves and to multiply to better advantage than in the city where the competition of life is keener. Although they are best off in a rural environment, when unrestricted and unsegregated they are a constant menace to the community and often involve it in considerable expense. As soon as farmers become aware of what the feeble-minded are costing the community, how they endanger its moral and physical health, and that when unrestricted they continue to reproduce incapables and thus perpetuate the burden, they will demand that some practicable and reasonable measures be taken for their control. The difficulty is that at present in most states there is no method whereby the feeble-minded can be committed to state institutions or be otherwise segregated unless they are paupers or unless they go voluntarily, nor is there any means of preventing their marriage and reproduction. Dairy farmers have learned that it pays to weed out the "boarder" cows from their herds and that if they breed from a scrub sire they will have scrub stock; but if the boarder cow was also inclined to become vicious and to corrupt the habits of the rest of the herd and the farmer knew this trait to be hereditary, he would invariably send such a cow to the butcher. I believe that as soon as farmers appreciate the biological significance of feeble-mindedness they will insist upon reasonable legislation for its control. _Delinquency._--The third class of abnormal citizens are the delinquents, both adult and juvenile. Almost every rural community has a certain number of adults and children who, although not definitely criminal, are constantly committing various misdemeanors, are vicious, or incorrigible, and there are occasional rural communities and neighborhoods which are as true slums as are found in the cities.[72] Drunkenness was formerly the greatest cause of delinquency, and the tavern and saloon were responsible for the prohibition movement whose staunchest supporters were rural people. The bootlegger and the illicit still continue the illegal traffic in liquor, but where prohibition has been in force for some time liquor has ceased to be an important factor in delinquency.
