Arthur Harris in the eastern and western United States, the Hawaiian islands, and Jamaica over a period of 18 years. Included more than 12,000 series of determinations of freezing-point depression, specific electrical conductivity, chloride and sulphate content in grams per liter of sap, and occasional determinations of hydrogen ion concentration. A separate index to the data is included for use by those wishing to make ecological studies of plants in particular communities.

This work provides a clear and comprehensive chronology of the Eastern Roman Empire from the foundation of Constantinople in 324 AD to the extinction of the last Byzantine principality in 1461 AD, ultimately shedding light on a once-obscure period of Eastern Mediterranean and Balkan history whose events still resonate in world politics.

Over the past fifty years, the history and culture of the Byzantine empire has ceased to be the preserve of a few scholars and is now taught and debated in universities all over the world.
