ACORNS AND OAKS. 



Of what size and weight are the acorns that 

 are to be produced a hundred years hence in that 

 little oak which is not yet a finger's length, and 

 wears the first leaves of its childhood ? 



A. 



B. 



A. Acorn germinating. The shell ruptured at 

 the top ; an umbilical vessel from each lobe of the 

 nut ; the germ at their union, but hardly visible. 



B. The young plant. The root extended ; the 

 plumule, or future stem, barely developed. Du- 

 rable trees make roots first.
