The old plea that we must have an army of celibate women because in civilized countries there is a preponderance of females does not hold at present in the United States. The census of 1910 shows an excess of 2,691,678 males in this country. Nor is this entirely due to immigration. More boys than girls are always born in civilized lands; and of native white people born of native parents in the United States there were, in 1910, 25,229,294 males and 24,259,147 females, a difference obviously due to natural causes. New England alone in America has a preponderance of females; and the excess there, as also in England and Germany, is needed all along the frontiers of civilization. With the industrial and social freeing of women now going on, we may reasonably hope that the communities of old maids left behind, through the emigration of young men, will be broken up. Of course, it will be pointed out that many men and women who do marry fail to realize the ideal presented in these pages. Every form of living is dangerous and not every one can hope to be a successful husband and father or wife and mother. Even devotion to religion furnishes many inmates for insane asylums; athletic contests leave a line of cripples behind them; and railroad disasters fill thousands of graves annually. The institution of marriage has had no such intelligence applied to its improvement during the past years as has been given to perfecting railroads; and since founding a family is a more difficult undertaking than making a journey, one need not be astonished at the number of fatalities. Even if the institution of marriage were as intelligently and carefully brought up to date as railroad systems are, it would still remain dangerous to live either in or out of marriage. And yet the danger could be greatly reduced by proper education of youth. At present we are educating 10,000,000 girls in the state schools of America, and as many boys. They are spending eight to twelve years, under the direction of celibate women teachers, sharpening their intelligence. Their most important work in life is to be the making of homes, but they are supposed to master this art through imitating the homes in which they grow up. Many of these are unworthy of imitation, and they are all in process of transition.
