Presented at the annual meeting of the American Institute of Biological Sciences, Corvallis, Oregon, August 30, 1962 / The study of tree-ring series, called dendrochronology, was originally conceived by A. E. Douglass as a tool for studying sun-spot cycles. He developed a system of cross- dating which provided for the accurate age determination of rings and this made possible the precise dating of archaeological sites. More recently Edmund Schulman used the width measurements of dated tree-rings as estimates of past climatic and stream -flow patterns.Such applications appeared to have greater precision when the tree -ring samples came from so called "sensitive sites" (i.e., drained ridges or slopes). The present study is the first of a series designed to further assess the effect of site and to provide an estimate of the relative magnitude of each of the sources of variation. The study is supported by the National Geographic Society, Wetherill Mesa Project at Mesa Verde National Park.

Dendrochronologists in their scientific inquiries use quantitative data, of which tree-ring widths form a major part. In order to gather the necessary quantitative tree-ring data, someone must be trained to measure the widths of the tree rings. The purpose of this paper is to explain to the person who will actually measure the tree-ring widths how the measuring process should be performed at the Laboratory of Tree-Ring Research. The following three sections describe the three phases of the measuring process. The first section deals with the preparations that must be performed before the ring widths can be measured. The second section describes the procedures for measuring the ring widths. The final section describes the checking procedure used to test the reliability of the measurements.

Ongoing research designed to expand a grid of tree-ring chronologies in the western U.S. that can be used to examine tree growth response to increasing atmospheric CO2 is summarized in this interim report. Current and projected sampling is designed to cover most of the Great Basin and the Southwestern U.S., focusing on long -lived species growing under stressful climatic conditions. Older trees growing in these circumstances provide the best potential for analytical discrimination of climatic and CO2 signals. A descriptive statistical summary of all current data sets is provided and potential directions of the project are discussed.
