SUGGESTIONS TO THE TEACHER 
We must insist again upon having specimens alive or dead 
in the school room when giving the lesson in Nature Study. 
Remember always, that no account, however well rendered, will 
have much value unless the scholar can observe directly with his 
eyes the facts to be learned. Our papers are made purposely 
brief and descriptions very meager, to leave many points to be 
determined by a study of the objects. 
The potato beetle is easily obtained in rural communities, 
and the teacher should store away a quantity of them in bottles 
for the winter’s use.
