This book highlights a problem that is still prevalent today in many parts of the world — that of landlord/tenant relationships. Hibernicus postulates that while Ireland is a very fertile place much suited to farming, it is not as productive as it could be. Sometimes the problem is that the land is owned and leased out by people who are interested only in the income they get and not in making an effort to maximise the income. Other times the landlord is anxious to improve productivity but is met with resistance from his tenant farmers.
