BOTANICAL CHARTS. 



Thoroughly Modified and Adapted 



for Use in the United States, 



by Eliza A. Youmans. 



A very interesting and valuable little 

 work, designed to supply an element- 

 ary knowledge of the principal facts of 

 plant-life, together with the means of 

 training beginners in the way to ob- 

 serve plants methodically and accu- 

 rately. 



The true objective method applied 

 to elementary flcienoe-teaching. Plants 

 themselves are the objects of study. 

 The pupil is told very little, and from 

 the beginning throughout lie is sent to 

 the plant to get his knowledge of the 

 plant. 



Introduces the pupil to the study of 

 Botany by the direct observation of 

 vegetable forms. 



This book takes the place of the au- 

 thor's '^Second Book of Botany,"" but 

 provides a complete course in itself no 

 other book being necessary. 



Designed to give an elementary ac« 

 count of Structural and Physiological 

 Botany, or of the inner and minute 

 mechanism and activities of plants. 



It treats of what the parts of a plant 

 are built up, and what functions they 

 perform in its history as a living being. 



Six Charts mounted on rollers, con- 

 taining nearly five hundred figures 

 colored to the life, which represent 

 twenty-four orders and more than forty 

 species of plants. An invaluable aid 

 in making the study of Botany intereat- 

 ing and attractive.
