The second section, Analysis of the Materials covers coring techniques, methods of measurement, and analysis. The third section surveys the sources of variations in ring width and wood density. The fourth section deals with the ways in which dendrochronology has been applied to solve problems in history, climatology, geomorphology, entomology, forestry and environmental sciences. The final chapter provides a review of the history of dendrochronology.
