IV PREFACE. 



with a thorough exposition of the system of Linnaeus, and 

 the outlines of that of Jussieu are given ; care being taken 

 that the facts, as stones, should be well joined together by 

 the cement of theory, so that the whole should form a 

 well-proportioned and enduring structure. Engravings 

 were required to assist the learner, and for that object 

 there is a profuse number. The ten chief medicinal 

 plants of the United States are figured, and, together 

 with their botanical description, is added an account of 

 their properties. Aware that a work of this character 

 would be peculiarly acceptable to youth, we have endeav- 

 ored to render it still more inviting by the addition of the 

 Meadow Queen's songs, with the necessary alterations, 

 they being unequaled for fixing in the young mind the 

 Linnsean classes. And with the hope that it may be as 

 valuable to the chill as to the parent, to the pupil as the 

 teacher, it is submitted to the public.
