second factor is just as important as the first, for racial progress; that 
one leg is just as important as the other, to a pedestrian. Its only con- 
flict with euthenics appertains to such euthenic measures as impair the 
adaptability of the race to the better environment they are trying to 
make. 
Some supposedly euthenic measures opposed by eugenics are not 
truly euthenic, as for instance the limitation of a superior family in 
order that all may get a college education. For these spurious 
euthenic measures, something truly euthenic should be substituted. 
Measures which show a real conflict may be typified by the infant 
mortality movement. There can be no doubt but that sanitation and 
hygiene, prenatal care and intelligent treatment of mothers and babies, 
are truly euthenic and desirable. At the same time, as has been 
shown, these euthenic measures result in the survival of inferior 
children, who directly or through their posterity will be a drag on the 
race. Euthenic measures of this type should be accompanied by 
counterbalancing measures of a more eugenic character. 
Barring these two types, euthenics forms a necessary concomitant 
of the eugenic program; and, as we have tried to emphasize, eugenics 
is likewise necessary to the complete success of every euthenic program. 
How foolish, then, is antagonism between the two forces! Both are 
working toward the same end of human betterment, and neither can 
succeed without the other. When either attempts to eliminate the 
other from its work, it ceases to advance toward its goal. In which 
camp one works is largely a matter of taste. If ona road there is a 
gradient to be leveled, it will be brought down most quickly by two 
parties of workmen, one cutting away at the top, and the other filling 
in the bottom. For the two parties to indulge in mutual scorn and 
recrimination would be no more absurd than for eugenics and euthenics 
to be put in opposition to each other. The only reason they have been 
in opposition is because some of the workers did not clearly understand 
the nature of their work. With the dissemination of a knowledge of 
biology, this ground of antagonism will disappear.
