on its bearers, but their qualities are neither diminishing nor eee 
and more and more are fitted to shoulder the burden. 
A younger country in developing its industries can profit by the expe- 
rience of the older and secure from the start better hygiene and a more 
effective education, can watch over its most favourable racial elements, 
establish a public opinion favourable to the early segregation of degenerate 
types, and, as Canada is doing, can limit immigration to those fit to become 
citizens of the great Dominion. 
Periodical surveys are necessary to check the changes in the population. 
Failing more extensive measures these may be effected through the 
records of the medical inspection of school children, though in these 
anthropometric data are but scanty. Toronto has long been known for 
its standard survey, and it is to be hoped that similar data will be collected 
in all parts of the Dominion. The matter is of great importance, since 
it is only on the basis of careful physical and mental surveys that legislation 
directed towards social and racial hygiene could properly be introduced 
and rightly justified. The lack of such information has been a great 
handicap to the discussion of such measures in Britain, and has allowed 
a freer play to pessimistic views. 
None the less, despite all forebodings, it may confidently be stated 
that the Mother Nation has remained true to herself and deserves now, as 
of yore, the encomiums of the ‘ Polychronicon’“”’: ‘Engelond ful of pley, 
fremen well worthy to pley, fre men, fre tonges, hert fre, fre helth al the 
leden.’
