XIV METHOD OF TEACHING. 



sodden vegetable debris, which when dried and prepared, forms 

 a valuable fuel. Nearly all the products of the soil can be utilized 

 for our requirements, and it is therefore important to know them 

 in order to be able to use them, and to draw from them all possible 

 advantages. 



It is ignorance of these elements of science which leads to 

 those gross errors and absurd prejudices which are really relics of 

 barbarism, and whicli must be unceasingly opposed by demon- 

 strating the simple truth, and disseminating this indispensable 

 knowledge. 



This elementary course of Natural History may be divided 

 into about 30 lessons ; and we shall rapidly point out what each 

 of them may include ; but it is obvious that they may be extended, 

 shortened or modified, according to the time which can be given 

 to them, and the special interest which such and such a portion

Three diagrams, one of each kingdom, must be necessarily 

 consulted to furnish examples. 



The importance of the study of man has given him a separate

 have kept it quite distinct.
