STERILITY OF THE CAPABLES. 153 



of things, will be the first to limit their fertility, no 

 doubt to their individual advantage, but to the det- 

 riment of the race at large. The work on population 

 by Malthus reads like a modern book. His contri- 

 butions to social, and his stimulus to biological science 

 can never be underestimated, but his advocacy of 

 those measures which insure relative sterility, such 

 as late marriages, etc., will lead to the final exter- 

 mination of those who follow his advice. The world 

 will fall to the share of those who produce most off- 

 spring. Let us be sure that in our own nation it shall 

 not be to the offspring of the deteriorated, but that 

 the generations that succeed us shall possess those 

 qualities of mind and body which we admire most 

 among our fellowmen, and which will only be pre- 

 served to the race if those possessing them carry out 

 fully their duties of motherhood and fatherhood.
