at college contribute less than
one child apiece to the race. The classes do not even reproduce their
own numbers. Instead of the 3.7 children which, according to Sprague's
calculation, they ought to bear, they are bearing .86 of a child.

The foregoing study is one of the few to carefully distinguish between
families which were complete at the time of study and those families
where additional children may yet be born. In the studies to follow this
distinction may in some cases be made by the reader in interpreting the
data while in other cases families having some years of possible
productiveness ahead are included with others and the relative
proportion of the types is not indicated. The error in these cases is
therefore important and the reader is warned to accept them only with a
mental allowance for this factor.

The best students make an even worse showing in this respect. The
Wellesley alumnae who are members of Phi Beta Kappa,--that is, the
superior scholars--have not .86 of a child each, but only .65 of a
child; while the holders of the Durant and Wellesley scholarships,
awarded for intellectual superiority,[122] make the following pathetic
showing in comparison with the whole class.

It must not be thought that Wellesley's record is an exception, for most
of the large women's colleges furnish deplorable figures. Mount
Holyoke's record is:

Nor can graduation from Bryn Mawr College be said to favor motherhood.
By the 376 alumnae graduated there between 1888 and 1900, only 138
children had been produced up to Jan. 1, 1913. This makes .84 of a child
per married alumna, or .37 o
