gently and successfully in our complicated and difficult 
environment. 
In this little book we give the pupils a set of terms which 
will enable them to express their thoughts on sex matters 
without the use of the vulgar words which they properly 
shun in talking with parent or teacher. We approach the 
subject from the standpoint of plants and lower animals, in 
which the structures and processes are less complicated and 
therefore more easily understood than in human beings. 
Then we pass with comparative ease and freedom of ex¬ 
pression to the discussion of human reproduction. 
Our individual happiness and success in life depend largely 
on our avoiding the sex pitfalls which waylay our path. Not 
only disease of body but also pollution of mind, which debar 
men and women from their highest attainments in life, 
result from the unwise use of the sex function. Therefore, 
the second and third chapters discuss the dangers of wrong 
sex conduct, and aim to bring the pupils to adopt for them¬ 
selves the course which leads, in sex matters, to a sound body 
and a wholesome mind. 
How much the pupil profits by these lessons depends on 
himself. These pages lead to an understanding of the mat¬ 
ter, but the pupil must learn to apply the teaching in his 
own life. He must adopt for himself the standard of sex 
conduct which will prepare him for the most wholesome 
conjugal life and bring him such children as will be a joy and 
blessing to his later years; and having adopted such a 
standard he must adhere to it, through trial and temptation, 
to the end of his days.
