eminent younger men,—those born between 1880 and 1889, New England, with 7.5% of the country's population, could claim only 12% of the genius. Cambridge, Mass., has produced more eminent younger men of the present time than any other city, he discovered, but the cities which come next in order are Nashville, Tenn., Columbus, Ohio, Lynn, Mass., Washington, D. C., Portland, Ore., Hartford, Conn., Boston, Mass., New Haven, Conn., Kansas City, Mo., and Chicago, Ill.
There is reason to believe that some of the old New England stock, which emigrated to the West, retains a higher fecundity than does that part of the stock which remains on the Atlantic seaboard. This fact, while a gratifying one, of course does not compensate for the low fertility of the families which still live in New England.
Within this section of the population, the decline is undoubtedly taking place faster in some parts than in others. Statistical evidence is not available, to tell a great deal about this, but the birth-rate for the graduates of some of the leading women's colleges is known, and their student bodies are made up largely of girls of superior stork. At Wellesley, the graph in Fig. 36 shows at a glance just what is happening. Briefly, the graduates of that 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
