6 PREFACH, 
thoughts of God, habits of mental activity, strength of judgment, and 
decision of character; and, moreover, to do all this by means of a study 
whose path, in a double sense, is strown with flowers, then is the study 
of Botany desirable; and that labor is not in vain which is bestowed 
upon the preparation of a work designed, like the present, for primary 
classes, from the ages of ten to fourteen. 
As the title implies, we have aimed to represent to the eye nearly every 
subject or form treated of, or described in these Lessons. But, notwith- 
standing the copiousness of these illustrations, neither the teacher nor the 
pupil will be satisfied to rely upon their aid alone, Nature alone can 
afford the proper illustrations in the study of Nature’s works, and it is 
only by comparison with the living specimen that eithsr the picture or 
the description becomes intelligible. Therefore let specimens in unlimited 
number accompany every botanical recitation. 
Most of the figures are original. Others have been derived from Maont, 
Payer, Richard, Balfour, Lindley, and a few, by permission, from Darl- 
ington’s “ Weeds and Useful Plants.” 
Finally, to the children and youth of our country, gathered in schools 
of every name, this humble volume is dedicated, with confident belief that 
it will prove to many of them a source of intellectual and moral culture 
as well as of pure and rational delight.
