84 GENERAL SCIENCE 



All hope of the progress of mankind, and one of the chief reasons 

 for maintaining schools, is that each individual and each generation 

 in turn may early become acquainted with the gains in knowledge 

 made by the race. This renders it unnecessary for anyone to repeat 

 the mistakes that others before him have made. 



Many of the evils experienced in the lives of people are the direct 

 results of wrong habits formed before the full significance of these 

 habits and of their results could be understood.
