Our conclusion, therefore, is that social and economic opportunities afford the leisure as well as cultural advantages for the improvement of talent; that the local environment is of vital importance, offering as it does the cultural advantages of cities of certain kinds and of chateaux, and that of the local environment the educational facilities are of the supremest importance. Consequently, it appears that Mr. Ward's estimate of one person of talent to the 500 instead of Mr. Galton's estimate of one to the 4,000 does not seem strained. Produce in society generally the opportunities and advantages which Geneva, Paris and the chateaux possessed and which gave them their great fecundity in talent, and all regions and places will yield up their potential or latent genius to development and the ratio will be obtained. This position is likely to be criticized, unless it is remembered that we admit that there is a hereditary difference at birth, and that all we seek to establish is that, given these differences, what conditions are likely to mature and develop the men of born talent. Thus after the appearance of my "Vocational Education" I received a letter from Professor Eugene Davenport in which he makes this statement: 'Ward's arguments as here employed seem to show that environment is a powerful factor in bringing out talent even to the exclusion of heredity. I doubt if you would care to be understood to this limit, and yet where you enumerate on page 61 the reasons why certain cities are fecund in respective talents, you seem to have overlooked the fact that if these cities have been for many generations centers of talent to such an extent as to provide exceptional environmental influences, the same conditions would also provide exceptional parentage, so that the birthrate of talent would be much higher in such a region than the normal. In other words, the very same conditions which would provide exceptional opportunities for development also and at the same time provide an exceptional birth condition. This is the rock on which very many arguments tending to compare heredity and environment wreck themselves.'[5] [5] This is a criticism that needs to be met. Mr. George R. Davies of this institution has submitted facts in a paper which appeared in the March number of the Quarterly Journal of the University of North Dakota, which fills in the gap. He shows relative to American cities that there has been little or no segregation of talented parentage.
