Let me indicate two or three conditions essential to success. DO not be afraid that I am going to moralize, or inflict a homily upon you. I speak upon the subject only from the view Of a man Of the world. Desirous of aiding you to become successful business men. You all know that there is no genuine, praise worthy success in life if you are not honest, truthful, fair-dealing. I assume you are and will remain all these, and also that you are determined to live pure, respectable lives, free from pernicious or equivocal associations with one sex or the other. There is no creditable future for you else. Otherwise your learn ing and your advantages not only go for naught, but serve to accentuate your failure and your disgrace. I hope you will not take it amiss if I warn you against three Of the gravest dangers which will beset you in your upward path.
