The Bostonians of your day had the reputation of being great askers of questions, and I am going to show my descent by asking you one to begin with. What should you name as the most prominent feature of the labor troubles of your day?« »Why, the strikes, of course,« I replied. »Exactly; but what made the strikes so formidable?« »The great labor organizations.« »And what was the motive of these great organizations?« »The workmen claimed they had to organize to get their rights from the big corporations,« I replied. »That is just it,« said Dr. Leete; »the organization of labor and the strikes were an effect, merely, of the concentration of capital in greater masses than had ever been known before.

Self-defense drove him to union with his fellows. The records of the period show that the outcry against the concentration of capital
