Among the smaller forces which operate upon the mind and tend toward strengthening and exalting the best ideals, are little books like this. They are especially valuable when so much of the author’s own experience forms a thread upon which are suspended jewels of thought and illustration serviceable to those who would see and know the best things. I have found these characteristics in this small volume, and gladly recommend it to all those who would become more familiar with what our author calls the key to that cabinet of character in which nature conceals not only the motive power of every-day life, but those latent talents and energies that, through a knowledge of self, we can bring to bear upon our lives.
