EDWARD. 



ARE you ready now, mamma, to read a descrip- 

 tion of the Houseleek ? 



MOTHER. 



Yes, my dear. But I wish I could have pro- 

 cured a flower that would show the character of 

 the class Dodecandria more distinctly : since the 

 number of stamens varies, under different circum- 

 stances, even in the same species, of the genera 

 which are native. The Houseleek, however, is 

 certainly placed in this class by botanists. Can 

 you tell me the order it is in ?
