PRACTICAL EDUCATION. 7l7 



dividual — and. possibly, for a particular class of individual — 

 but largely by the s])irit of higher social self-preservation. 



But even now the total outlay for education is but an in- 

 significant jiart of the total social expenditure, yet that outlay 

 is ])robal)ly one of the most effective for the social good ever 

 devised. It would be interesting to compare the social expendi- 

 ture upon advertising — which, though necessary, can scarcely be 

 described as so socially productive as education. The State has 

 fostered in the past public professional schools and colleges, 

 normal training colleges for teachers, schools for military instruc- 

 tion, and those for higher agricultural work and the engineering 

 professions, and it has made vocational education a part of its 

 contribution to dependent and delinquent children; it is now en- 

 gaged U})on the question of general vocational instruction through 

 the National Advisory Board for Technical Education, and it 

 behoves every parent and every person with the social good at 

 heart to demand, and to bear a share in meeting the cost of, 

 efficient vocational education by daylight based ujx^n the best 

 of all forms of comjndsion — the will of the people.
